Splitting a string arrays into two different arrays : <p>It's required to split each string from networkList array into <code>addresses</code> and <code>ports</code> arrays.</p>
<pre><code>string[] networkList = { "127.0.0.1:8000", "127.0.0.1:8888", "8.8.8.8:80" };
string[] addresses, ports;
</code></pre>
<p>I'm really sorry of asking so dumby question, but I couldn't find a good function to do this. I know there are few that could help.</p>

Do I cast the result of new? : In the answers to the question https://stackoverflow.com/questions/605845/do-i-cast-the-result-of-malloc was covered that I do not need and should not cast the returned `void` pointer of `malloc()`.
But how is it about the `new` operator in C++?
_____________________________
Is there an explicit reason to do:
````
int *p_rt = new int;
````
instead of
````
int *p_rt = (*int) new int;
````
Or can I do the cast?

SwiftUI @State var initialization issue : <p>I would like to initialise the value of an <code>@State</code> var in SwiftUI trough the <code>init()</code> method of a <code>Struct</code>, so it can take the proper text from a prepared dictionary for manipulation purposes in a TextField.
The source code looks like this:</p>
<pre><code>struct StateFromOutside: View {
let list = [
"a": "Letter A",
"b": "Letter B",
// ...
]
@State var fullText: String = ""
init(letter: String) {
self.fullText = list[letter]!
}
var body: some View {
TextField($fullText)
}
}
</code></pre>
<p>Unfortunately the execution fails with the error <code>Thread 1: Fatal error: Accessing State<String> outside View.body</code></p>
<p>How can I resolve the situation? Thank you very much in advance!</p>

BrowserRouter vs Router with history.push() : <p>I am trying to understand the difference between <code>BrowserRouter</code> and <code>Router</code> of the <code>react-router-dom</code> (v5) package and what difference it makes for my example below.</p>
<p>The documentation says:</p>
<blockquote>
<p><strong>BrowserRouter</strong>
A that uses the HTML5 history API (pushState,
replaceState and the popstate event) to keep your UI in sync with the
URL.</p>
</blockquote>
<p>Source: <a href="https://reacttraining.com/react-router/web/api/BrowserRouter" rel="noreferrer">https://reacttraining.com/react-router/web/api/BrowserRouter</a></p>
<blockquote>
<p><strong>Router</strong>
The common low-level interface for all router components. Typically
apps will use one of the high-level routers instead: BrowserRouter, HashRouter, MemoryRouter, NativeRouter, StaticRouter</p>
</blockquote>
<p>Source: <a href="https://reacttraining.com/react-router/web/api/Router" rel="noreferrer">https://reacttraining.com/react-router/web/api/Router</a></p>
<p>From what I understand is that I should be using <strong>BrowserRouter</strong> for my HTML5 browser apps and I have been doing this so far.</p>
<p><strong>history.push(...) example:</strong></p>
<p>I am trying to perform a <code>history.push('/myNewRoute')</code> within a thunk:</p>
<pre class="lang-js prettyprint-override"><code>import history as './history';
...
export function someAsyncAction(input) {
return dispatch => {
fetch(`${API_URL}/someUrl`, {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify({ input }),
}).then(() => {
history.push('/myNewRoute');
}).catch((err) => {
dispatch(setError(err));
})
};
};
</code></pre>
<p><code>history</code> is defined as this module:</p>
<pre class="lang-js prettyprint-override"><code>import { createBrowserHistory } from 'history';
export default createBrowserHistory();
</code></pre>
<p>and the <code>history</code> is also passed to my router:</p>
<pre class="lang-js prettyprint-override"><code>import { BrowserRouter as Router } from 'react-router-dom';
import history as './history';
...
const App = () => (
<Router history={history}>
...
</Router>
);
</code></pre>
<p><strong>Problem:</strong> <code>history.push()</code> will update the URL in the browser bar but not render the component behind the route.</p>
<p>If I import <code>Router</code> instead of <code>BrowserRouter</code>, it works:</p>
<pre class="lang-js prettyprint-override"><code>// Does not work:
import { BrowserRouter as Router } from 'react-router-dom';
// Does work:
import { Router } from 'react-router-dom';
</code></pre>

iOS different constraints for different devices : <p>I have a ViewController designed for iPhone SE</p>
<p><a href="https://i.stack.imgur.com/smK62.png" rel="noreferrer"><img src="https://i.stack.imgur.com/smK62.png" alt="enter image description here"></a></p>
<p>As you can see I also have a constraint <code>Align Top to: Safe Area Equals 75</code></p>
<p>The question is, is it possible to change this value for iPhone 8 and iPhone 8 Plus? For example:</p>
<ul>
<li>SE = 75 </li>
<li>8 = 85 </li>
<li>8 Plus = 105</li>

how to check if today is between two dates in Twig? : <p>I'd like to check if today's date is between two dates from the database. Here's my code.</p>
<pre><code>{% if today < room.price_start_date and today > room.price_end_date %}
<a href="{{'/'|app}}/book/{{room.id}}"><button type="button" class="btn btn-default btn-xs">Book this room</button></a>
{% else %}
<a href="{{'/'|app}}/contact"><button type="button" class="btn btn-default btn-xs">Book this room</button></a>
{% endif %}
</code></pre>
<p>The <code>today</code> variable gets its value from this code:</p>
<pre><code>$todayDate = date('Y-m-d');
$this['today'] = date('Y-m-d', strtotime($todayDate));
</code></pre>
<p>The <code>price_start_date</code> and <code>price_end_date</code> I get them from database and their columns' type is <code>Date</code></p>
<p>Any idea how to check if <code>today</code> is between <code>room.price_start_date</code> and <code>room.price_end_date</code> in Twig?</p>

React-Native Offline Bundle - Images not showing : <p>I have a React-Native app I'm trying to deploy in Release mode to my phone. I can bundle the app to the phone. Database, Video and audio assets are all in there but no images are showing in the UI. </p>
<p>I have done the following to 'bundle' my app:</p>
<ol>
<li>in the project folder in Terminal run <code>react-native bundle --platfrom ios --dev false --entry-file index.ios.js --bundle-output main.jsbundle</code></li>
<li>Drag the reference to the <code>main.jsbundle</code> file into XCode under <code>myapp</code> folder</li>
<li>In XCode, open <code>AppDelegate.m</code> and uncomment <code>jsCodeLocation = [[NSBundle mainBundle]…</code></li>
<li>Open <code>Product > Scheme > Edit Scheme</code> then change <code>Build Configuration</code> to <code>Release</code></li>
<li>Select <code>myapp</code> under the project navigator and then:
under <code>TARGETS: myappTests</code> > <code>Build Phases</code> > <code>Link Binary With Libraries</code>
press <code>+</code>
select <code>Workspace</code> > <code>libReact.a</code> and <code>Add</code></li>
</ol>
<p>When I try and compile in XCode with the <code>../node_modules/react-native/packager/react-native-xcode.sh</code> setting in <code>myapp > targets > myapp > Bundle React Native code and images</code> it fails with <code>error code 1</code>. </p>
<p>I've seen LOADS of posts on this and I've tried:</p>
<ul>
<li>to check <code>Run script only when installing</code>- the app then installs but with no images</li>
<li>adding <code>source ~/.bash_profile</code> to react-native-xcode.sh - the app build fails</li>
</ul>
<p>Any help would be greatly appreciated! </p>

Angular 4, convert http response observable to object observable : <p>I'm new to the concepts of observables and need some help with a conversion.<br>
I have a service which returns an <code>Observable<Response></code> from a Http request, but I need to convert it do an <code>Observable<PriceTag></code> to use it on a <code>DataSource</code> inside the connect method.<br>
Is there anyway to do this?</p>
<p>This is the method from my service:</p>
<pre><code>getPriceTags(): Observable<Response> {
// Set the request headers
const headers = new Headers({ 'Content-Type': 'application/json' });
// Returns the request observable
return this.http.post(Constants.WEBSERVICE_ADDRESS + "/priceTag", null, {headers: headers});
}
</code></pre>
<p>And here is the DataSource class where I need to return it as an <code>Observable<PriceTag></code>:</p>
<pre><code>export class PriceTagDataSource extends DataSource<PriceTag> {
constructor (private priceTagService: PriceTagService) {
super();
}
connect(): Observable<PriceTag> {
// Here I retrieve the Observable<Response> from my service
const respObs = this.priceTagService.getPriceTags();
// Now I need to return a Observable<PriceTag>
}
disconnect() {}
}
</code></pre>
<p>Here's an example from the response from my request:</p>
<pre><code>{
// This object is used to check if the query on the server was sucessful
"query": {
"sucessful": true
},
// These are my PriceTags
"tags": [
{
"id": "1",
"name": "MAIN"
},
{
"id": "2",
"name": "CARD"
}
]
}

How to declare a 3-Dimensional Array with very big size in C? : <p>I'm trying to create a 3 Dimensional array <strong>S[ ][ ][ ]</strong>...</p>
<p>when the size is small for example:</p>
<pre><code> m=40;
int S[m][m][m];
memset(S, 0, sizeof(S[1][1][1])*m * m * m); //initialize all the array with 0//
for (i=1 ; i<=m ; i++ ) {
k=1;
for (j=1 ; j<=n ; j++ ) {
if(statement) { //if statment true i put in S array a value//
S[i][i][k]=j; k++;}
</code></pre>
<p>it works fine(for small size like S[ 40 ][ 40 ][ 40 ]... When the size is big, for example:</p>
<pre><code> m=1500;
int S[m][m][m];
memset(S, 0, sizeof(S[1][1][1])*m * m * m);
....

<p>My question is that...I would like to write a simple chat program that could communicate with a win7 client(Gf) and that sounds cool except linux is not windows :D. So I would like to know...What should i do? Change to Python or etc?Is it possible to make it in C#?I just need some "pointer" to select the best option of"route". :D</p>

Ruby thinks an integer I'm passing as an argument is a method : I am trying to write a simple function in ruby but keep getting this error: undefined method `b' for main:Object (NoMethodError).
Here is the code I have written can anyone tell me why I keep getting this.
def get_sum(a,b)
if a == b do
return a
end
else
total = 0
for num in a...b
total += num
end
return total
end
end
This is obviously something really simple but would like to know why it is happening. Thanks in advance. | 0debug |
Using retryWhen to update tokens based on http error code : <p>I found this example on <a href="http://sapandiwakar.in/refresh-oauth-tokens-using-moya-rxswift/" rel="noreferrer">How to refresh oauth token using moya and rxswift</a> which I had to alter slightly to get to compile. This code works 80% for my scenario. The problem with it is that it will run for all http errors, and not just 401 errors. What I want is to have all my other http errors passed on as errors, so that I can handle them else where and not swallow them here.</p>
<p>With this code, if I get a <code>HttpStatus 500</code>, it will run the authentication code 3 times which is obviously not what I want.</p>
<p>Ive tried to alter this code to handle only handle <code>401</code> errors, but it seem that no matter what I do I can't get the code to compile. It's always complaining about wrong return type, <code>"Cannot convert return expression of type Observable<Response> to return type Observable<Response>"</code> which makes no sense to me..</p>
<p>What I want: handle 401, but stop on all other errors</p>
<pre><code>import RxSwift
import KeychainAccess
import Moya
public extension ObservableType where E == Response {
/// Tries to refresh auth token on 401 errors and retry the request.
/// If the refresh fails, the signal errors.
public func retryWithAuthIfNeeded() -> Observable<E> {
return self.retryWhen {
(e: Observable<ErrorType>) in
return Observable.zip(e, Observable.range(start: 1, count: 3), resultSelector: { $1 })
.flatMap { i in
return AuthProvider.sharedInstance.request(
.LoginFacebookUser(
accessToken: AuthenticationManager.defaultInstance().getLoginTokenFromKeyChain(),
useFaceBookLogin: AuthenticationManager.defaultInstance().isFacebookLogin())
)
.filterSuccessfulStatusCodes()
.mapObject(Accesstoken.self)
.catchError {
error in
log.debug("ReAuth error: \(error)")
if case Error.StatusCode(let response) = error {
if response.statusCode == 401 {
// Force logout after failed attempt

What are the benefits of cfn-init over userdata? : <p>My CloudFormation template has gotten pretty long. One reason is because my <code>AWS::CloudFormation::Init</code> section has gotten pretty huge. This is a very small sample of what I have:</p>

<p>Wouldn't it be better to just put this into the userdata section as a bunch of commands?</p>

Disable default constructor in Rust? : <p>Say I define my own type in a Rust library, like so:</p>
<pre><code>struct Date {
year: u16,
month: u8,
day: u8
}
impl Date {
fn new(y: u16, m: u8, d: u8) -> Date {
// Do some validation here first
Date { year: y, month: m, day: d }
}
}
</code></pre>
<p>Is there a way to <strong>require</strong> users to use the <code>Date::new</code> constructor? In other words, can I somehow prohibit users from creating their own Date struct with the default constructor like so:</p>
<pre><code>let d = Date { 2017, 7, 10 };
</code></pre>
<p>I ask because it seems to be a detrimental flaw if you cannot force developers to run their arguments through a battery of validation before setting the members of a struct. (Although, maybe there is some other pattern that I should use in Rust, like validating data when they are used rather than when they are created; feel free to comment on that.)</p>

the Slider.php code is :

$this->load->model('My_data');
$data['manset']= $this->My_data->get_manset();
$this->load->view('slider_view' ,$data);

My_data.php code is;
public function get_manset() {
// $sorgu =
// mysql_query("select * from manset, haberler
// where manset.onay='1' and manset.link=haberler.id and haberler.onay='1'

$this->db->select('*');
$this->db->from('manset as man, haberler as hab');

$query = $this->db->get();
if ($query->num_rows() > 0) {
return $query->result();
} else {
return $query->result();
}
and the slider_view.php code is:
foreach($manset as $row){
$baslik =$row->baslik;
$icerik =$row->icerik;
$link =$row->link;
$img_path =$row->img_path;

}
now when ı called
http//example.com/index.php/Slider/manset_al
every think is ok, the slider is running. But
when ı get the slider in giris.php with this code;
$this->load->view('slider_view');
it's not run and say: undefined variable manset;
how can ı fix it?
Thank you.

compiler cannot compile inheritance c++ : <p>Suppose i have a header which contain these two classes </p>
<pre><code>class A:public class B{
// code
};
class B
{
protected:
A a_object;
};
</code></pre>
<p>when the compiler compiles this include file,when it comes to Class A ,it sees class A inherits from B but it doesn't reach to Class B definition.So it gives an error. and if i reverse the order of both classes,it gives error due to a_object as it doesn't see Class A definition. </p>
<p>So how to solve this problem? and assume that i restricted to this include file to have class A and B definitions.</p>
<p>Thanks</p>

Combining PHP-fpm with nginx in one dockerfile : <p>I have a need to combine the php-fpm with nginx in one dockerfile for production deployment. </p>
<p>So is it better to :</p>
<p>(1) Start the dockerfile using php:7.1.8-fpm and then install nginx image layer on top of it ? </p>
<p>(2) Or do you recommend using nginx image and then installing php-fpm using apt-get ?</p>
<p>PS: I do not have a docker-compose build option for production deployment. On my development environment, I already use docker-compose and build multi-container app easily from two images. Our organization devops do not support docker-compose based deployment for prod environment.</p>

How to model common information for Rails application : <p>I'm a bit new in rails development I'm modeling a website with few resources and so far so good. But here is my question:</p>
<p>I would like to allow the admin users to manage information show in most of the pages: Application name, telephone number, address, default email and this kind of things.</p>
<p>My current idea is make a model Property with name and value, but somehow I'm not convinced about this approach because I'll need to access the database to get this values for every request.</p>
<p>Thanks everyone for your time! :D</p>

Xcode 8.2 returning hundreds of errors when including SwiftyJSON.swift : I am learning swift at the moment and recently tried to use SwiftyJSON to parse JSON data. However, following a tutorial, when I dragged the SwiftyJSON.swift file into my project window, it immediately shows 100+ errors in the SwiftyJSON file. Because of this, I am unable to use SwiftyJSON in my projects and can't gather data from the web. I am using Xcode 8.2 and learning Swift 3.0.
Has anyone else had this problem, and have a solution to it?
Sorry if this is a really dumb question by the way. | 0debug |
Interface vs Implementation in C++. What does this mean? : <p>I am learning the concepts of inheritance, especially about access-specifiers, here I am confused about the <code>protected</code> access specifier. The members under protected can be accessible by the base class member functions and derived class member functions. There is a chance of messing up <code>implementation</code> of base class if we declare protected as access specifier. Its always better to declare data members under <code>private</code> rather than protected as only the <code>interface</code> is exposed and not the <code>implementation</code> section. We are declaring only the variables in the private section of a class and how it becomes <code>implementation</code>? Implementation will be done in the <code>member functions</code> right? The terms are confusing, can anyone clarify and explain me the terms?</p>

What's the different between those css selectors? : <pre><code>element element div p Selects all <p> elements inside <div> elements 1
element>element div > p Selects all <p> elements where the parent is a <div> element 2
element+element div + p Selects all <p> elements that are placed immediately after <div> elements 2
element1~element2 p ~ ul Selects every <ul> element that are preceded by a <p> element
</code></pre>
<p>When I see the course of w3schools, it explain those four selectors by that, but I am very confusing for the explain especially the first term and the second term, it looks like the same thing, anybody can give simple examples to explain what's different for those four selectors?</p>

CORS security with mobile apps : <p>We need to keep our API server security with CORS restriction : </p>
<pre><code>Access-Control-Allow-Origin : http://myonlinesite.com
</code></pre>
<p>But we also needs this API to be accessible for our mobile apps (Android+iOs).</p>
<p>All the solutions I found tell me to allow all origin : <code>*</code> , but this would be a big security failure for our API.</p>
<p>We are building our apps with Cordova, which WebView serves local files and therefore sends : <code>origin: null</code> , for all its http(s) requests. So we are thinking about adding <code>null</code> to the allowed origin. It's better, since it will block every other website attempting to fetch our API, but it will allow any mobile apps to fetch it...</p>
<p>Is there any more interesting solution for this ?</p>
<p>Thank you!</p>

readline doesn't stop line reading after rl.close() emit in nodejs : <p>I have the following file I want to read line by line and stop reading it once I have found "nameserver 8.8.8.8".</p>
<pre><code>nameserver 8.8.8.8
nameserver 45.65.85.3
nameserver 40.98.3.3
</code></pre>
<p>I am using nodejs and the readline module to do so</p>
<pre><code>const readline = require('readline');
const fs = require('fs');
function check_resolv_nameserver(){
// flag indicates whether namerserver_line was found or not
var nameserver_flag = false;
const rl = readline.createInterface({
input: fs.createReadStream('file_to_read.conf')
});
rl.on('line', (line) => {
console.log(`Line from file: ${line}`);
if (line === 'nameserver 8.8.8.8'){
console.log('Found the right file. Reading lines should stop here.');
nameserver_flag = true;
rl.close();
}
});
rl.on('close', function(){
if (nameserver_flag === true){
console.log('Found nameserver 8.8.8.8');
}
else {
console.log('Could not find nameserver 8.8.8.8');
}
});
}
check_resolv_nameserver();
</code></pre>
<p>Since I emit a close event with rl.close() as soon as I read the first match, I would expect my Code to read only the first line and then stop reading further. But instead my output looks like this</p>
<pre><code>Line from file: nameserver 8.8.8.8
Found the right file. Reading lines should stop here.
Found nameserver 8.8.8.8
Line from file: nameserver 45.65.85.3
Line from file: nameserver 40.98.3.3

How to set OkHttpClient for glide : <p>I am using Glide to load images, the issue I'm facing is that when i run app on slow internet connection I'm getting <code>SocketTimeOutException</code>. So to solve this issue i want to use a custom <code>OkHttpClient</code> so that I can change the timeout of HttpClient this is the code i have. </p>
<pre><code>public class MyGlideModule implements GlideModule {
@Override
public void applyOptions(Context context, GlideBuilder builder) {
}
@Override
public void registerComponents(Context context, Glide glide) {
OkHttpClient client = new OkHttpClient();
client.setConnectTimeout(15, TimeUnit.SECONDS);
client.setReadTimeout(15,TimeUnit.SECONDS);
OkHttpUrlLoader.Factory factory = new OkHttpUrlLoader.Factory(client);
glide.register(GlideUrl.class, InputStream.class, factory);
}
}

<p>but <code>OkHttpUrlLoader</code> is not there any more in Glide API. So i was wondering how can set the OkHttpClient for Glide </p>

How to select nth item inside select element in cypress : <p>say I have the HTML:</p>
<pre><code><select name="subject" data-testid="contact-us-subject-field">
<option value="What is this regarding?">What is this regarding?</option>
<option value="Partnerships">Partnerships</option>
<option value="Careers">Careers</option>
<option value="Press">Press</option>
<option value="Other">Other</option>
</select>
</code></pre>
<p>Selecting an option with a known value, such as 'Careers' is as easy as:</p>
<pre><code>cy.get('[data-testid="contact-us-subject-field"]').select('Careers');

ContentCachingResponseWrapper Produces Empty Response : <p>I'm trying to implement filter for logging requests and responses in <code>Spring MVC</code> application.
I use the following code:</p>
<pre><code>@Component
public class LoggingFilter extends OncePerRequestFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(LoggingFilter.class);
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
ContentCachingRequestWrapper requestWrapper = new ContentCachingRequestWrapper(request);
ContentCachingResponseWrapper responseWrapper = new ContentCachingResponseWrapper(response);
LOGGER.debug(REQUEST_MESSAGE_FORMAT, requestWrapper.getRequestURI(), requestWrapper.getMethod(), requestWrapper.getContentType(),
new ServletServerHttpRequest(requestWrapper).getHeaders(), IOUtils.toString(requestWrapper.getInputStream(), UTF_8));
filterChain.doFilter(requestWrapper, responseWrapper);
LOGGER.debug(RESPONSE_MESSAGE_FORMAT, responseWrapper.getStatus(), responseWrapper.getContentType(),
new ServletServerHttpResponse(responseWrapper).getHeaders(), IOUtils.toString(responseWrapper.getContentInputStream(), UTF_8));
}
}
</code></pre>
<p>So, I get my request and respone logged as expected. Here are the logs:</p>
<pre><code>2016-10-08 19:10:11.212 DEBUG 11072 --- [qtp108982313-19] by.kolodyuk.logging.LoggingFilter

<p>However, the empty response is returned. Here's the output from <code>curl</code>:</p>
<pre><code>$ curl http://localhost:9015/resources/1 --verbose

How to pass basic auth credentials in API call for a Flutter mobile application? : <p>I'm working on a simple Flutter mobile app that needs to call out to an API that uses Basic Auth.</p>
<p>I can hit the API in Postman using email & password credentials and it encodes the email & password in Base64 (I assume with a ":" separating) before performing the request.</p>
<p>I'm not sure how to do this in Flutter / Dart...</p>
<p>I've tinkered with the http package and tried to do the Base64 encoding... but I just get back errors from the server.</p>
<p>Can anyone provide some guidance or an example for a basic auth request?</p>

System.out.println(d);
if(d.equals("01")){

Python writing general script using open('file', 'r') : I am writing a script where I first read a file using
`with open('file', 'r') as file`,
do some operation, and then write it to a new file using
`with open(`newfile`, 'w') as newfile`.
My question is, what do I need to change in the script to make it general for a number of files, so that I can just call the script with the file name from the terminal like `python3 script.py file.ext`? Also, is there a way to write the output back into the original file using this method?
Any help is greatly appreciated! | 0debug |

Embedding react-boilerplate in Rails 5.1 : <p>Has anyone tried integrating <a href="https://github.com/react-boilerplate/react-boilerplate" rel="noreferrer">react-boilerplate</a> into a Ruby on Rails 5.1 app? It looks like the <a href="https://medium.com/@hpux/rails-5-1-loves-javascript-a1d84d5318b" rel="noreferrer">5.1 approach to embedding React components in views</a> is fairly simple. Rails 5.1 is using <a href="https://github.com/rails/webpacker" rel="noreferrer">webpacker</a> which has its approach to mixing Ruby configuration with Webpack. It doesn't seem very straightforward, but does anyone have any techniques for accomplishing this?</p>

C++ Programming, having trouble programming finding velocity and distance : <p>Hey I'm a beginner taking an intro to C++ class, and this is my first assignment. I posted this a couple of days ago but I still am somewhat lost. I have to use the formulas: d=v0*t + 1/2*g<em>t^2, and v= v0 + g</em>t. where v0 stays constant at 0 and g also stays constant at 9.807 m/s^2. I keep getting one error which is "expected unqualified-id before "{" token" on the first { and cannot seem to fix them, and im sure this code is incorrect, so can you help me figure this out?</p>
<pre><code>#include <cstdlib>
#include <iostream>
#include <math.h>
using namespace std;
const float GRAVITY = 9.807, INITIALVELOCITY = 0;
int seconds;
{
cout << "Please enter the time in seconds." << endl;
cin >> seconds;
} //end function Time
int main(int argc, char *argv[])
{
float distance, velocity, seconds;
void getSeconds (void);
cout.setf (ios::fixed,ios::floatfield);
cin >> seconds;
while (seconds > 0) {
distance = INITIALVELOCITY * seconds + (0.5 * GRAVITY * pow(seconds, 2));
velocity = INITIALVELOCITY + (GRAVITY * seconds);
cout.precision (0);
cout << endl << "WHEN THE TIME IS" << seconds << "SECONDS THE DISTANCE"
"TRAVELED IS" << distance << "METERS THE VELOCITY IS" << velocity <<
"METERS PER SECOND.";
cout. precision(1);
cout<< seconds << distance << velocity << endl << endl;
}
system ("PAUSE");
return EXIT_SUCCESS;
} //end main
</code></pre>

Weird issue in C : <p>thanks for your help.
<br>I'm trying to similate a simplified version of ARM, and I have a very weird error in c <a href="http://pastebin.com/3XRdngty" rel="nofollow noreferrer">http://pastebin.com/3XRdngty</a> .<br>
I don't understant why in the function executer_code(),
the for doesn't work ...<br>
I mean it should be looping untill the variable "i" is equal to the variable nombre_instruction, <br>but it turns out that the variable "nombre_instruction" is the right value the first time it goes in<br> the for, but the second time it doesn't go in the for because its value changed to 0,<br> I search on the internet if someone has the same kind of error, <br>and i didn't find anything.<br>I reread my code but still I cannot figure out why it does this, 3 hours has passed already.
And thank you again for you help :)</p>

Storing a string list in a new csv file : I am new to Python and somehow can't quite get this simple task to run.
I have generated a randomization of some images I would like to later present to each participant in my experiment. The randomization assigns each participant a particular order for a list of images to be presented. I end up, for example, with a list that looks like this (for one participant):
str_all = ['01_2.jpg', '06_2.jpg', '08_1.jpg', '04_2.jpg', '10_1.jpg',
'07_2.jpg', '02_1.jpg', '05_2.jpg', '09_1.jpg', '03_1.jpg']
For each participant this list is different. Before a new randomization is generated for a new participant to get a new "str_all" list, I would like to store the string elements in a way that I can use them to retrieve those images later. I created manually with Excel a new csv file called list_stim.csv. I would like to have each list in one row (each row = one participant) but don't know if this is the best way to place each. I tried doing this but it did not work:
with open('list_stim.csv', 'w') as fp:
wr = csv.writer(fp, delimiter=',')
wr.writerows([str_all[i]])
wr.writerow("\n")
Any advice? Thank you! | 0debug |
