Do raw strings in python disable meta characters such as \w or \d just as they do with \n? : <p>I am new to Python. Can someone tell me what is the difference between these two regex statements (re.findall(r"\d+","i am aged 35")) and (re.findall("\d+","i am aged 35")).</p>
<p>I had the understanding that the raw string in the first statement will make "\d+" inactive because that is the primarily role of a raw string - to make escape characters inactive. In other words "\d+" will not be a meta character for finding/searching/matching digits if a raw string is used. However, I now see that both statements return the same result. </p>

View function prototypes in C : <p>Often during programming contests I forget which library contains which function. Hence I require some C code which can print the available functions with a specific library. eg. usage:</p>
<p><code>showAvailFunctions("stdlib.h")</code></p>
<p>and it would print all the available functions with <code>stdlib.h</code> library</p>

program that determines if array is ascending, descending, or random(C language) : <p>i have to build a program that scans "size", then array in the size of "size".
returns 1 if ascending, -1 if descending, and 0 if neither.</p>
<p>so for I've came up with this, and its not working.</p>
<pre><code>int UpOrDown(int *arr,int size)
{
int i,j,flag;
if(arr[0]<arr[1])// ascending or random
{
flag=1;
{
for(i=1;i<size;i++)
if(arr[i]>arr[i+1])
flag=0;
}
if (flag=0) return 0;
else return 1;
}
else //descending or random
{
flag=-1;
if(arr[0]>arr[1])
{
for(i=1;i<size;i++)
if(arr[i]<arr[i+1])
flag=0;

im a big c++ noob and I need help starting out a block of code for my program : <p>so i am making a code that takes data from a txt file and gets its variance.
The formula that my teacher required us to use needs the program to square the decimals in the txt file and then gets its sum. unfortunately i do not have a sample of code because I do not know where to start. I was only able to store the data in the text file into a vector.</p>
<pre><code>ifstream dataInput("D:\\Users\\Rodolfo Obre\\Documents\\Ateneo De Manila\\Intersession 2019\\Engg 21\\Programs\\Text Files\\Data Set.txt");
double readNumber;
vector<double> dataSet;
if (!dataInput.is_open()) {
cerr << "The file can not be opened\n";
exit(1);//exits the program
}
while (dataInput >> readNumber){
dataSet.push_back(readNumber);
}
cout << "n is equal to " << dataSet.size() << endl;
double sum=0;
for (int i=0; i < dataSet.size(); i++){
sum += dataSet[i];
}
cout << "The sum of the data is " << sum << endl;
</code></pre>
<p>This block of code takes the data from the txt file, counts how many there are and then takes its sum.</p>
<p>I have no idea how I to do the part where i need to take each decimal in the text file, raise it to the power 2 and then get the sum of all of the values.</p>

Ask a question about swift, about array type conversion, thank you！ : class Model: NSObject {
var numbers : Array<Int> = []
}
internal func test() {
let model : Model = Model.init()
model.setValue([1,2,3], forKey: "numbers")
print(model.numbers)
}
test()//[1, 2, 3]
But if I change the above "var numbers : [Int] = []" to "var numbers :[Int64] = []", it will crash. Why is that? How can I solve it?

Learning how to use pointers in c++ running into Error 'variable not declared in scope' : <p>As the title says, I am learning how to use pointers in C++. I have been tasked with writing a program that gets data about countries from a text file, loads them into an array of class objects, then lets the user view the data, remove an entry or quit.</p>
<p>I'm running into a problem with class accessor functions. I am getting the error 'variable not declared in scope.' I get what this error is trying to tell me, but I can't figure out how to get the accessors to function properly. </p>
<p>The requirements for the assignment are to use char-pointers to store strings, so I think that's adding an extra level of complexity. I want the accessor function to just return a single variable, e.g. country name, capital and surface area.</p>
<p>I am using CodeBlocks and running on Ubunutu. I have the compiler set to c++11.</p>
<p>Anyways, here is the code:</p>
<pre><code>//This is the main.cpp file
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
#include "Country.h"
const int FILE_PATH_SZ = 512;

void getArrSize(ifstream& inFile, string pathName, string& countriesData);
void fillCountryArr(ifstream& inFile, string pathName, string& countryName, string& capitalName, string& tempSurfaceArea);
void printCountryData(Country** g_countryArray, int g_arrsz);
int main() {
char menuChoice, startingLetter;
string pathName, countriesData, countryName, capitalName, tempSurfaceArea;
ifstream inFile;
do {
cout << "Choose one of the following:" << endl << endl;
cout << "Menu options" << endl << endl;
cout << "a) Read a text file:" << endl;
cout << "b) Remove countries starting with given letter" << endl;
cout << "c) Print all data to console" << endl;
cout << "d) Quit" << endl;
cin >> menuChoice;
switch (menuChoice)

case 'a':

getline(inFile, tempSurfaceArea); //gets the surface area of the country in the form of a string
surfaceArea = stol(tempSurfaceArea); //converts the string version of surface area to an integer
g_countryArray[i] = new Country(countryName.c_str(), capitalName.c_str(), surfaceArea); //creates new Country class and stores address in the i'th element of g_countryArray
} //passes the name of the country and capital of the country in to the constructor as
//c-strings and passes surfaceArea as an int

<p>The function just above here printCountryData is where I want to pass the array of class objects and array size variables, then call the accessor functions.</p>

countryLen = strlen(country); //gets length of country name
capitalLen = strlen(capital); //gets length of capital name
name_ = new char[countryLen + 1]; //dyanmically creates a new character array of size countryLen and stores base address of array in name_ pointer
for (int i = 0; i < countryLen; i++)//transfers storage of country name to the name_ array

}
char* GetCapital()

<p>It's these 3 accessor functions at the bottom that are generating the error 'name_ is not declared in this scope, etc.'</p>

Swift: Programmatically make UILabel bold without changing its size? : <p>I have a UILabel created programmatically. I would like to make the text of the label bold without specifying font size. So far I have only found:</p>
<pre><code>UIFont.boldSystemFont(ofSize: CGFloat)
</code></pre>
<p>This is what I have exactly:</p>
<pre><code>let titleLabel = UILabel()
let fontSize: CGFloat = 26
titleLabel.font = UIFont.boldSystemFont(ofSize: titleLabelFontSize)
</code></pre>
<p>But this way I am also setting the size. I would like to avoid that. Is there a way?</p>
<p>If there is no way, what would be a good workaround in Swift?</p>
<p>Thank you!</p>

How to have a transparent gradient over an Image in React Native iOS? : <p>I have been dealing with the a gradient rectangle over an Image that has a black and a transparent sides, I have been looking about a gradient object in react native and I didn't found, but there is a react-native module that does this, but the problem is that it does work in android the transparency, but in iOS, it doesn't work, it shows white in place of the transparent side</p>

<pre><code>CAGradientLayer *gradientMask = [CAGradientLayer layer];
gradientMask.frame = self.imageView.bounds;
gradientMask.colors = @[(id)[UIColor whiteColor].CGColor,

Flutter: Get passed arguments from Navigator in Widget's state's initState : <p>I have a <code>StatefulWidget</code> which I want to use in named route.

<p>Now, I need to access these argument's in the state's <code>initState</code> method as the arguments are needed to subscribe to some external events. If I put the <code>args = ModalRoute.of(context).settings.arguments;</code> call in <code>initState</code>, I get a runtime exception.</p>

Organization proxy self signed certificate not trusted in cent os VM : <p>I am having a VM created out of Cent OS 7.6 ISO. when I try to CURL <a href="https://xxxxxxx" rel="nofollow noreferrer">https://xxxxxxx</a> it shows "(60) CURl Peer certificate issuer has been marked as not trusted by the user. This happens even after I downloaded the certificate and aded it to the store using update-ca-certificate command (ref: <a href="https://manuals.gfi.com/en/kerio/connect/content/server-configuration/ssl-certificates/adding-trusted-root-certificates-to-the-server-1605.html" rel="nofollow noreferrer">https://manuals.gfi.com/en/kerio/connect/content/server-configuration/ssl-certificates/adding-trusted-root-certificates-to-the-server-1605.html</a>). The only doubt I have is that the client system is behind my organization network proxy.
Is there any suggestion to solve the problem?</p>

Retrive data Firebase from DateTime node : I want to retrive data from `Firebase` but my problem is that one of the node is date for each day and I don't know how to get inside of it.
That's my `JSON` :

How is StaticLayout used in Android? : <p>I need to build my own custom <code>TextView</code> so I have been learning about <code>StaticLayout</code> to draw text on a canvas. This is preferable to using <code>Canvas.drawText()</code> directly, or so the <a href="https://developer.android.com/reference/android/text/StaticLayout.html" rel="noreferrer">documentation</a> says. However, the documentation doesn't give any examples for how do it. There is only a vague reference to <a href="https://developer.android.com/reference/android/text/StaticLayout.Builder.html" rel="noreferrer"><code>StaticLayout.Builder</code></a> being the newer way to do it.</p>
<p>I found an example <a href="http://ivankocijan.xyz/android-drawing-multiline-text-on-canvas/" rel="noreferrer">here</a> but it seems a little dated.</p>
<p>I finally worked though how to do it so I am adding my explanation below.</p>

Passing pointers (matrix) to a function in c : <p>I have dynamically created a matrix using calloc in the usual way:</p>
<pre><code>int **matrix;
int dim,r;
scanf("%d",&dim);
matrix=(int **)calloc(dim, sizeof(int *));
for(r=0; r<dim; r++)
{
matrix[r]=(int *)calloc(dim, sizeof(int));
}
</code></pre>
<p>Now if I wanted to create a function to just print the elements of this matrix, I should write something like:</p>
<pre><code>void stampmatrix(int **matrix, int dim)
{
int r=0, c=0;
for(r=0; r<dim; r++)
{
printf("(");
for(c=0;c<dim;c++)
{
printf(" %d , ",matrix[r][c]);
}
printf(")");
}
}
</code></pre>
<p>And this works fine.
Now I add this line to the previous function</p>
<pre><code>`...`
matrix[r][c]=1;
printf(" %d , ",matrix[r][c]);
...
</code></pre>
<p>If i call this function in my main function,
stampmatrix(matrix,dim)
once i run the program, the compiler should create a copy of my matrix, fill it with 1, and then print them, and then return to my main function <strong>without changing the actual matrix</strong>. But if I do this and then i check in my main function the values of my matrix elements, they are changed to 1.
In class i was told that if I pass values to a function, the program creates a copy of the values, works with them and then cancel the copy, so I need to pass addresses to a function in order to actually change the contents of my variables in my main function.
Why in this case it doesn't work, and changes my matrix values? It's because I still pass pointers to the function stampmatrix? I really don't understand. Shouldn't the function be something like:</p>
<pre><code>void stampfunction(int dim, int ***matrix)
</code></pre>
<p>Or it's because i used a void function?
Thanks for the attention!</p>

Does git gc execute at deterministic intervals? : <p>I've been reading up on git, and I have a very particular question I am struggling to answer.</p>
<p><strong>When</strong> does <code>git gc</code> execute autonomously?</p>
<p>I've been hearing through the grape-vine of various forums that it occurs by default on a push or a fetch/pull - but I cannot find any source that verifies this. Even <a href="https://www.kernel.org/pub/software/scm/git/docs/git-gc.html" rel="noreferrer">the documentation itself</a> only gets this specific (emphasis mine):</p>
<blockquote>
<p><strong>Some</strong> git commands <strong>may</strong> automatically run git gc; see the --auto flag below for details</p>
</blockquote>
<p>and the <code>--auto</code> flag specifies</p>
<blockquote>
<p><strong>Some</strong> git commands run git gc --auto after performing operations that could create many loose objects.</p>
</blockquote>
<p>I want to be able to deterministically say:</p>
<p>"Loose tree and blob files will not have been cleaned up by git until one of the following commands is run: <strong>{mystery list here}</strong>. When running one of these commands, if the number of loose objects exceeds the value of <code>gc.auto</code>, git will automatically compress the objects into a packfile".</p>

Correct S3 Policy For Pre-Signed URLs : <p>I need to issue pre-signed URLs for allowing users to GET and PUT files into a specific S3 bucket. I created an IAM user and use its keys to create the pre-signed URLs, and added a custom policy embedded in that user (see below). When I use the generated URL, I get an <code>AccessDenied</code> error with my policy. If I add the <code>FullS3Access</code> policy to the IAM user, the file can be GET or PUT with the same URL, so obviously, my custom policy is lacking. What is wrong with it?</p>
<p>Here's the custom policy I am using that is not working:</p>
<pre><code>{
"Statement": [
{
"Action": [
"s3:ListBucket"
],
"Effect": "Allow",
"Resource": [
"arn:aws:s3:::MyBucket"

How to use @HostBinding with @Input properties in Angular 2? : <p>(Angular 2 RC4)</p>
<p>With <a href="https://angular.io/docs/ts/latest/api/core/index/HostBinding-var.html">@HostBinding</a> we should be able to modify properties of the host, right? My question is, does this apply to @Input() properties as well and if so, what is the correct usage? If not, is there another way to achieve this?</p>
<p>I made a Plunker here to illustrate my problem: <a href="https://embed.plnkr.co/kQEKbT/">https://embed.plnkr.co/kQEKbT/</a></p>
<p>Suppose I have a custom component:</p>
<pre><code>@Component({
selector: 'custom-img',
template: `
<img src="{{src}}">
`
})
export class CustomImgComponent {
@Input() src: string;
}
</code></pre>
<p>And I want to feed the src property with an attribute directive:</p>
<pre><code>@Directive({
selector: '[srcKey]'
})
export class SrcKeyDirective implements OnChanges {
@Input() srcKey: string;
@HostBinding() src;
ngOnChanges() {
this.src = `https://www.google.com.mt/images/branding/googlelogo/2x/${this.srcKey}_color_272x92dp.png`;
}
}
</code></pre>
<p>Why can't this directive change the [src] input property of the custom component?</p>
<pre><code>@Component({
selector: 'my-app',
directives: [CustomImgComponent, SrcKeyDirective],
template: `<custom-img [srcKey]="imageKey"></custom-img>`
})
export class AppComponent {
imageKey = "googlelogo";
}

C++ How to create a class template that allows no argument list in its constructor : I apologize if my title is confusing. What I'm trying to do is create a class template implementing the std::map from scratch. What I want to achieve is to not use specific data types in the argument list of my constructor. Please see the code below:
#include "pch.h"
#include <iostream>
#include <string>
using namespace std;
template<typename T, typename N>
class MyCustomMap
{
public:
MyCustomMap();
T* keys;
N* values;
};
template<typename T, typename N>
MyCustomMap<T, N>::MyCustomMap()
{
this->keys = new T[10];
this->values = new N[10];
}
....
....
int main()
{
MyCustomMap<int,string> map; //This works because I specified the argument list
MyCustomMap map; //This is my goal
return 0;
}
Is this possible? Any help is appreciated, thank you.

In need of an IDE to make an app with a powerful Ui : <p>I'm starting to study mobile development and i want to know what is the best language/IDE to develop an app with a powerful UI. I prefer a android native app over a web one, but it can be an hybrid. I've already tried with C# in visual studio and xamarin, but it looks confusing. I want to build those crazy smooth modern and flat UI apps, so what's the best IDE?</p>

Show entire bottom sheet with EditText above Keyboard : <p>I'm implementing a UI where a bottom sheet will appear above the keyboard with an EditText for the user to enter a value. The problem is the View is being partially overlapped by the keyboard, covering up the bottom of the bottom sheet.</p>
<p>Here is the Bottom Sheet and no keyboard.</p>
<p><a href="https://i.stack.imgur.com/Yz3x1.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Yz3x1.png" alt="Bottom Sheet"></a></p>
<p>Here is the Bottom Sheet with the keyboard showing.</p>
<p><a href="https://i.stack.imgur.com/9THkr.png" rel="noreferrer"><img src="https://i.stack.imgur.com/9THkr.png" alt="enter image description here"></a></p>
<p>What's the best method to ensure the entire Bottom Sheet is shown?</p>
<p>Thanks.</p>
