but I get error when compile. The program has unexpectedly finished and myprogram.exe crashed. I compile successfully when I delete line 1,2 in code above. Are there something wrong with my code? How could I use QVector as a member of class?

Which Boost features overlap with C++11?

I put my C++ skills on the shelf several years ago and it seems now, when I need them again, the landscape has changed.

We have got C++11 now, and my understanding is that it overlaps many Boost features.

Is there some summary where those overlaps lie, which Boost libraries going to become legacy, recommendation of which C++11 features to use instead of boost ones and which better not?

Does SpriteKit support dense tessellation of a sprite / texture / shape so it can be warped freely?

For example if you have an image of a trampoline, and a character jumping on it. Then you want to animate how the trampoline bends down in the center.

To do this I would have to take a bitmap and apply it to a densely tessellated OpenGL ES mesh. Then apply texture to it. Then deform the mesh.

Does SpriteKit support this or can it only display textures as-is?

UILabel doesn't show up in my application

Want to see if any value in one vector matches the value in another vector

I am writing code for a game called Bulls & Cows. I have already solved seeing if the value of one vector (if they are in the same index) are identical. However, I am not sure how to write a for loop that will move through two vectors and see if any value in one matches the value of any other index in the other vector. I would appreciate any help. Thank you!

I integrated a UIPickerView in my view and I want to add Strings dynamically.

here is my var declaration

var pickerDataSource : [String] = [String]()

how do I add String in a for statement ? such as

}

Prevent xml bomb XercesDOMParser - C++

I am using XercesDOMParser to read an xml file in linux (c++), I want to prevent xml bomb (Billion laughs) so I set these properties:

parser->setDoNamespaces(true)
parser->setDisableDefaultEntityResolution(true)
parser->setEntityResolver(NULL)
parser->setSkipDTDValidation(true)

However, it doesn't help and bomb still remain. Do you know how to prevent it (I have to use xerces with DOM only)

Find SECOND shortest path in directred graph

I need a way to find second shortest path in directed graph, on top of that second shortest path cannot include the shortest path entirely. I am aware of dijkstra algoritm, but I am unable to figure out a simple way on how to change that algorithm to give me a second shortest path in a reasonable amount of time. Algorithm, sudo-code or c++ example, one of the three will be greatly appreciated.

Printing the above half triangle is quite easy but I couldn't figure out how to print the lower triangle.

This is how I printed the above half triangle.

int num = 1;
for (int i = 1; i <= n; i++)
{
    for (int j = 1; j <= i; j++)
    {   
        cout << num;
        if (i != j)
        {  
             cout << "*";
        } 
          num++;
    }
    cout << endl;

How to tile a Sprite Node's Texture?

Using SpriteKit, how would I tile a SKTexture that repeats itself horizontally to fill the width of the SKSpriteNode? This is what I have so far - only stretches the texture.

    var header = SKSpriteNode()
    let headerTexture = SKTexture(imageNamed: "inGameHeader-1.png")
    header = SKSpriteNode(texture: headerTexture)
    header.position = CGPoint(x: 0, y: CGRectGetMaxY(self.frame)-39)
    header.size.width = CGRectGetWidth(self.frame)
    header.size.height = 150
    header.anchorPoint = CGPoint(x: 0,y: 1)
    addChild(header)

PLP feature extraction from a signal

I am wondering if anyone knows how to calculate the PLP(Perpetual Linear Prediction) features of an audio input. I am looking for two things:

1. there is severe lack of good documentation that may explain what and how exactly these features are calculated. So I'd appreciate if anyone can point me towards a documentation maybe?

2. Any c++ code snippet that shows the implementation maybe?

iOS: How to talk to Apple's SD card reader?

I want to get a list of the files on the SD card that is in the Apple SD card reader. I can usually create an EASession, although that is not reliably happening, but I also have no info about the protocol, called com.apple.accessory.updater.app.20.

Can anyone here fill me in about the Apple SD card reader i.e. part #A1595? How do I talk to it?

Why is decltype(a, b) is evaluated to a reference?

According to this answer, ref should be an int.

But for some reason it evaluated to int&, both in gcc and MSVC2015, while decltype(b) is correctly evaluated to just int. Why so?

int a = 1, b = 2;
decltype(a, b) ref; // ref is int&
decltype(b) var;    // var is int

C++: Remove == or any other operator for specific types

If I have a class called classA that has a typecast overload of classB and classC, how can I disable the == operator for classA being typed as classC?

class classA{
   operator classB();
   operator classC();

   //Remove this comparison possibility:
   operator ==(classC firstObject,classC secondObject)
}

Follow over from this question:

How can I change different UINavigationBar Style in a UINavigationController?

I want to change the color and translucent of the UINavigationBar in one viewController without influence on other viewControllers. It seems impossible because they share a common UINavigationBar. Some similar questions tell me to change the style of UINavigationBar in viewWillAppear and restore it in viewWillDisappear.But I can see the effect is not perfect. I want to know how can the follow app can do this. It seems it does not share a common UINavigationBar

VS2015 CE - Cannot Find Link.exe

I am trying to compile some open source software (Rust language) that requires Visual Studio 2015 with C++ support. My PATH variable must include the location of link.exe.

I presently have Visual Studio 2015 Community Edition installed, and both of the C++ Redistributables (x86 and x64). I cannot locate link.exe in any of the directories.

Where can I find link.exe? Does it live somewhere else? Is my installation damaged?

Installing libpqxx

I'm trying to install libpqxx to visual studio 2013. I have postgreSQL installed and working, but when I attempt to install libpqxx by running "nmake /f win32/vc-libpq.mak ALL" from the visual studio command line I get two errors. First I get bad_alloc, then it tells me "fatal error U1077" and gives the path to the visual C++ compiler.

Does anyone have any idea what could be done to fix this?

Do primitive types have also constructors in C++?

I have read in Dr. Bjarne Stroustrup Book "The C++ Programming Language" 3rd edition that built in types have also constructors in C++ in section 10.4.2.

But then the following link says that POD types can't have constructors:

http://www.parashift.com/c++-faq-lite/pod-types.html

Which is true? Do primitive types have also constructors in C++?

After 24 hours Firebase stops working but if I update pods it starts working again

I am working on Firebase and I have one query. I have login through Firebase and have fired insert, update, delete queries.

Here is my code:

[self.data observeEventType:FIRDataEventTypeChildAdded withBlock:^(FIRDataSnapshot * _Nonnull snapshot) {
        NSArray *array = snapshot.value;
        NSLog(@"%@",array);
    }];

This block works perfectly but after every 24 hours it stops calling. However, if I update pod then again it starts working.

Cordova Detect if user is leaving app or starting call (iOS)

I recently discovered Cordova, and started building an app that i've been thinking of. I need to figure out if i, through Cordova, can detect if the user is leaving the app (not locking the phone), or e.g. picking up a phone call, is there an event for this that i can bind to? I've searched through the most npm-library packages and did a lot of research but can't really find a good answer.

Is there analogy of boost compute function in Thrust?

I wonder if there is an analog to boost compute Function (http://www.boost.org/doc/libs/1_61_0/libs/compute/doc/html/boost_compute/advanced_topics.html#boost_compute.advanced_topics.custom_functions ) that turns into kernel and can be created as embedded inline code that turns into a kernel?

OpenCV .xml file copying for object detection

Replacing #define

I want to replace a

#define INTERVAL_MASK(b) (1 << (b))

with a inline function.

int INTERVAL_MASK(int b)
{
    return (1 << b);
}

But I have a switch case, which uses the preprocessor directive in the case statements. How to go about converting this? Replacing the switch with if is the only option?

UIView alpha 0 but still receive touch events?

I am trying to hide a uiview but still have it receive touch events. I am setting the alpha to 0 like so:

mainView.alpha = 0.0

also I've tried setting this to true but it doesn't do anything

mainView.userInteractionEnabled = true

Trouble is it no longer receives touch events when I do this. How can I enable it to receive touch events but be effectively hidden?

Inheritance with Virtual function

Consider a base class having a virtual function and parent class inherits this base class and implements that function. Say if a child class inheriting parent class has a function with same definition , does it override? Also, I am trying to implement features in such a way that base class has a virtual function and parent class inherits base class but does not implement it but the child class inheriting from parent class implements it. Is this allowed?

Looping in Firebase [Swift]

I have been trying to find a way to print/isolate each of the children in a part of the JSON data structure in Firebase. I am using swift and another post mentioned and verified this as the solution: for child in snapshot.childSnapshotForPath("vets").children { print(child.key); } but this is not valid because it comes with this warning: Ambiguous use of 'key' how do you recommend I loop through the data? All help is greatly appreciated!
