printf the value of %n in the same call - senseless? : <p>I can't find out the intention of the following part of <code>printf</code> specification at <a href="http://en.cppreference.com/w/cpp/io/c/fprintf" rel="noreferrer">cppreference.com</a>:</p>
<blockquote>
<p>There is a sequence point after the action of each conversion
specifier; this permits storing multiple %n results in the same
variable and <strong>printing the value stored by %n earlier within the same
call.</strong></p>
</blockquote>
<p>This reads as if the result of one (or even several) <code>%n</code> conversion specifier(s) could be printed out in the same <code>printf</code>-statement.
But I can't find out how this could ever be achieved, because all arguments passed to a call of <code>printf</code> are evaluated before <code>printf</code>'s body is entered (there is a sequence point after argument evaluation). Hence, the value of a variable to which a <code>%n</code> would write is evaluated before <code>printf</code> has the chance to overwrite this variable's value with the "number of characters written so far":</p>
<pre><code>#include <stdio.h>
int main( int argc, char* argv[] )
{
int n = 0;
printf("Hello, world!%n (%d first n); %n (%d second n)", &n ,n, &n, n);
// will print out "Hello, world! (0 first n); (0 second n)"
return 0;
}
</code></pre>
<p>My question: If there isn't any chance of "printing the value stored by %n earlier within the same call", isn't then the respective part of the <code>printf</code> specification senseless or misleading?</p>
<p>What is the actual sense of the <a href="http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf" rel="noreferrer">c99 standard</a> statement:</p>
<blockquote>
<p>7.19.6 Formatted input/output functions
(1) The formatted input/output functions shall behave as if there is a sequence point after the
actions associated with each specifier.</p>
</blockquote>
<p>Is it to reduce the "chances" of getting undefined behaviour?</p>
<p>The question is tagged with c++ and c, because I think that this topic applies the same way to both languages.</p>

javascript: difference in return value between operators -- and -= : <p>Given the following code:</p>
<pre><code>var x = 0;
function decrement(num) {
return num--;
}
var y = decrement(x);
console.log(y); // 0
</code></pre>
<p>Versus the following:</p>
<pre><code>var x = 0;
function decrement(num) {
return num -= 1; // this is the only difference between the functions
}
var y = decrement(x);
console.log(y); // 0
</code></pre>
<p>Why does <code>y--</code> return <code>0</code> from the function while <code>y -= 1</code> returns <code>-1</code>?</p>

How to call strings inside a list in Python : <p>So, I'm making a chat bot, and I want to enable it so if the user inputs a word/phrase thats in the dictionary (a pickled file), it will reply with a suitable message to what the user input. It might make more sense if you see the code:</p>
<pre><code>""" startup """
import pickle
'''opening the dictionary'''
inFile = open('words.txt', 'rb')
dictionary = pickle.load(inFile)
'''printing the dictionary'''
print("PRE TESTS...")
print("-")
print("Pickle protocol import:")
print(dictionary)
print("END OF PRE TESTS...")
print("-")
print(" ")
""" end of startup """
print("Hello! My name is Pinnochio. I'm currently very young, and my communication is extremely limited.")
print("-")
''' handling the replies '''
reply = input()
if reply != dictionary:
print("Sorry, I don't know that word.")
reply = input()
if reply == dictionary[0] | dictionary[1] | dictionary[2]:
print("Hey there")
reply = input()
if reply == dictionary[3]:
print("I'm feeling great!")
reply = input()
if reply == dictionary[4] | dictionary[5]:
print("It is, isn't it?")
reply = input()
</code></pre>
<p>The dictionary is a list inside another file, which I've pickled:</p>
<pre><code>import pickle
dictionary = ["hello", "hi", "hey", "how are you?", "good morning", "good afternoon"]
outFile = open('words.txt', 'wb')
pickle.dump(dictionary, outFile)
outFile.close()
</code></pre>
<p>Thanks in advance!</p>

How to make VSCode to replace the word when accepting autocomplete hint? : <p>JetBrains IDE platform have very useful feature, which I am using a lot and I find it a performance booster. When I have a word in editor, and I want to change or update that word, I do the following.</p>
<ul>
<li>Place cursor in front of the word (or in middle, ex. when I want to change only last part.)</li>
<li>Start typing until I got autocomplete I want to use.</li>
<li>Press TAB or ENTER.
<ul>
<li>On TAB - Old word is completely replaced by new word. This is especially useful when I update some names, in which beginning of word is the same, but ending is different. For example, change <code>getTimeInSeconds()</code> to <code>getTimeInMinutes()</code> - I put cursor after <code>getTimeIn</code>, get autocomplete, and press TAB. Nothing left to delete, everything is replaced.</li>
<li>On ENTER - New word is replaced from the start of old word, but right part from the cursor stays on screen.</li>
</ul></li>
</ul>
<p>By default VSCode supports only "ENTER" use case. Does it support "TAB" use case? If so, how to enable it?</p>

Is there a dict.update(sub_dict) function for list in Python? : Suppose a list in Python -> mylist:

Is there a function like update() for list too just like for dictionary? | 0debug |
C# Get computer name from IP : <p>I'm using Xamarin Studio to develop to iOS and I need a couple of functions to get the Computer Name from the IP and vice-versa</p>

try
{
IPHostEntry hostEntry = Dns.GetHostEntry(ipAdress);
machineName = hostEntry.HostName;
}
catch (Exception ex)

// Machine not found...
}
return machineName;

<p>But I keep getting the machine IP Address, so it's useless because I input the IP Address and get the IP Address.</p>
<p>I've tried something alike to get the IP Address from the HostName I always get the exception "Unable to resolve hostname <em>HITMAN-DESKTOP</em>" being the <em>HITMAN-DESKTOP</em> my remote machine that is accessible from any point in the network and online during the tests.</p>
<p>Any ideas?</p>

How do I specify the name of the file I want to read, as a variable? : I'm trying to write a program that can store the contents of a file into a variable chosen by the user.
For example, the user would choose a file located in the current directory and would then choose the variable he/she wanted to store it in.
This is a segment of my code so far.
```
print("What .antonio file do you want to load?")
loadfile = input("")
open(loadfile, "r")
print("Which variable do you want to load it for? - list_1, list_2, list_3")
whichvariable = input("")
if whichvariable == "list_1":
list_1 = loadfile.read()
elif whichvariable == "list_2":
list_2 = loadfile.read()
elif whichvariable == "list_3":
list_3 = loadfile.read()
else:
print("ERROR")
```
When I input that `loadfile = list1.antonio` (which is an existing file) and `whichvariable = list_1` it throws me this error:
```
Traceback (most recent call last):
File "D:\Antonio\Projetos\Python\hello.py", line 29, in <module>
list_1 = loadfile.read()
AttributeError: 'str' object has no attribute 'read'
```
I have tried all sorts of things and I haven't find a solution.
I'm from a non-english speaking country, so plz forgive me if my grammar is bad.

<p>Context:
At a garage sale one day, you stumble upon an old school video game. In this video game, your
character must take a journey along an n × n grid, collecting rewards along the way. Specifically,
there is an n × n matrix A with nonnegative entries, and your character collects a reward equal to
Aij if he visits the cell (i, j) of the grid. Your objective is to maximize the sum of rewards collected
by your character.
(a) [4 points]. The rules of level one of the game are as follows. Your character starts at the
top-left corner — i.e., cell (1, 1) — of the grid, and must travel to the the bottom-right corner —
i.e., cell (n, n) — in sequence of steps. At each step, your character is allowed to move either one
cell to the right or one cell down in the grid; stepping upwards, to the left, or diagonally is not
2
allowed. Show how to compute the optimal journey in O(n
2
) time.</p>

Why i need decision tree to predict my test data when i'm giving large training data to Train computer? : I'm a student of BSCS, I'm learning data mining. 1 question in mind has totally confused me. If I had made or written my coding for decision tree then why I need Large training data to predict answers of my test data? How training data is helping me when I am checking my each test data line through some lines of codes? Passing them through step by step, if at any step they are not matching my conditions I'm writing no in answer if they are passing all conditions successfully then I'm writing Yes in answer using my code. Now how training data is helping ? if it help computer to predict then why I need my decision tree or model to answer my data?? | 0debug |

Embedded Postgres for Spring Boot Tests : <p>I'm building a Spring Boot app, backed by Postgres, using Flyway for database migrations. I've been bumping up against issues where I cannot produce a migration that generates the desired outcome in both Postgres, and the embedded unit test database (even with Postgres compatibility mode enabled). So I am looking at using embedded Postgres for unit tests.</p>
<p>I came across <a href="https://github.com/opentable/otj-pg-embedded" rel="noreferrer">an embedded postgres</a> implementation that looks promising, but don't really see how to set it up to run within Spring Boot's unit test framework only (for testing Spring Data repositories). How would one set this up using the mentioned tool or an alternative embedded version of Postgres?</p>

VBA to Remove specfic reference created from file : I put together the following SQL to add a reference to a workbook.
Sub Add_Reference()
Dim vbProj As Object
Set vbProj = ActiveWorkbook.VBProject
vbProj.References.AddFromFile "C:\User\documents\Master_file.xlsm"
CleanUp:
Set vbProj = Nothing
End Sub
I thought I would be ale to do the same to `remove` by switching out the `AddFromfile` with `Remove` as follows:
Sub Remove_Reference()
Dim vbProj As Object
Set vbProj = ActiveWorkbook.VBProject
vbProj.References.Remove "C:\User\documents\Master_file.xlsm"
CleanUp:
Set vbProj = Nothing
End Sub
When I run `Remove_Reference` I get a `Type mismatch` error on the `vbProj.References.Remove "C:\User\documents\Master_file.xlsm"` line. Im guessing I need to call it something else but I am not sure what it should be.
Any ideas? | 0debug |

How to calculate duration & distance with setAvoid() : I receive the same duration & distance whether or not I am expecting to avoid highways or tolls
I suspect the issue is either in my order of operations, or the way I am calculating distance & duration
I have tried setting up setAvoid in two different ways (see code), as well as changed my if statements to accommodate what the HTML form (check box) might return.
I have also tried switching the if statement to "return formObject.avoid1"
this showed me that the if statement is functioning properly - so either the .setAvoid is not working the way I have written it, or the distance & duration calculations are not considering the setAvoid
if (formObject.avoid1 == "TRUE"){
mapObj.setAvoid(Maps.DirectionFinder.Avoid.HIGHWAYS);
}
if (formObject.avoid2 == "yes"){
mapObj.setAvoid("tolls");
}
var directions = mapObj.getDirections();
var bestRoute = directions["routes"][0];
var numLegs = bestRoute["legs"].length;
for (var c=0; c<numLegs; ++c){
var legNum = directions["routes"][0]["legs"][c];
var legDistance = legNum["distance"]["value"];
var legDuration = legNum["duration"]["value"];
totalDistance += legDistance;
totalDuration += legDuration;
}
If we are in fact avoiding highways, I expect the duration to increase, but I get the same duration whether or not we avoid highways | 0debug |

difference between npm run and nmp start? : <p>we have a lot of ts code which we can compile and run via "npm run dev". This allows us to hit the test js code via localhost. however, in the chrome debugger, 90% of the code is not visible (anonymous), and code which is not is too generic (such as find) to figure out how the thing which the debugger is showing as being slow or called a lot relates to our source code.</p>

Save content of Spark DataFrame as a single CSV file : <p>Say I have a Spark DataFrame which I want to save as CSV file. After <strong>Spark 2.0.0</strong> , <strong>DataFrameWriter</strong> class directly supports saving it as a CSV file.</p>
<p>The default behavior is to save the output in multiple <strong>part-*.csv</strong> files inside the path provided. </p>
<p>How would I save a DF with :</p>
<ol>
<li>Path mapping to the exact file name instead of folder</li>
<li>Header available in first line</li>
<li>Save as a single file instead of multiple files.</li>
</ol>
<p>One way to deal with it, is to coalesce the DF and then save the file. </p>
<pre><code>df.coalesce(1).write.option("header", "true").csv("sample_file.csv")
</code></pre>
<p>However this has disadvantage in collecting it on Master machine and needs to have a master with enough memory. </p>
<p>Is it possible to write a single CSV file without using <strong>coalesce</strong> ? If not, is there a efficient way than the above code ?</p>

JS Count words in a string WITHOUT using a regex : There are many posts on the topic of how to count the number of words in a string in JS already, just wanted to make it clear I looked at these.
http://stackoverflow.com/questions/18679576/counting-words-in-string
http://stackoverflow.com/questions/6543917/count-number-of-words-in-string-using-javascript
As a very new programmer I would like to perform this function without the use of any regular expressions. I don't know anything about regex and so I want to use regular code, even if it is not the most effective way in the real world, for the sake of learning.
I cannot find any answer to my question elsewhere, so I thought I would ask here before I default to just using a regex. | 0debug |

Python3: How to make a function that can set a max size in stack : My native language is not English so there is an error with my sentences.
I made a stack below.
Now I want to add a function or method that allows you to specify the maximum size of the stack.
How do I need to change or add?
```
class MyStack:
def __init__(self):
self.myList = []
self.top = -1
self.size = 0
```
def isEmpty(self):
if (self.size > 0):
return False
else:
return True
def push(self, item):
self.myList.append(item)
self.size = self.size + 1
self.top = self.top + 1
def pop(self):
if self.isEmpty():
return None
else:
self.ret = self.myList.pop(self.top)
self.size = self.top - 1
self.top = self.top - 1
return self.ret
def peek(self):
if self.isEmpty():
return None
else:
return self.myList[self.top]

componentDidMount and constructor : <pre><code> class ProductsIndex extends Component {

console.log(this) // #1. this logs ProductsIndex component
fetch('someUrl')

.then(res => console.log(this)) // #2. this logs ProductsIndex component
fetch('someUrl')
.then(res => res.json())
.then(console.log) // #3. this logs [{..},{..},{..},{..}]
}
componentDidMount(){
fetch('someUrl')
.then(res => res.json())
.then(console.log) // #4. this logs [{..},{..},{..},{..}]
}
</code></pre>
<p>As shown in the code above, both #1 and #2 point to same <strong><em>this</em></strong>. And also as shown, both #3 and #4 returns <strong>same</strong> array. However, why the code below doesn't work??</p>
<pre><code> class ProductsIndex extends Component {
constructor (props){
super(props);
fetch('someUrl')
.then(res => res.json())
.then(arr => {
this.state = {
array: arr
}
})
}
</code></pre>
<p>It throws an error saying that <strong>this.state</strong> is <strong>null</strong> and I really don't understand why.</p>
<p>Below code is the solution. could anyone please explain what exactly the difference is??</p>
<pre><code> class ProductsIndex extends Component {
constructor (props){
super(props);
this.state = {
array: []
}
}
componentDidMount(){
fetch('someUrl')
.then(res => res.json())
.then(arr => {

golang Read(p []byte) doesnot read full byte? : Recently I use golang Read(p []byte),intending to read full len(p) bytes. However I find that Read does not guarantee read len(p) bytes.That's,I need read 4 bytes but actually it gives me only 1.At last I use io.ReadFull instead.Now I am confused, what's the meaning of the function? What's the proper scene using Read?It may just read less bytes than you need. | 0debug |
