Question

I’m trying to learn how to use ppl.h in c++ . But I’m not sure what kind of solution I should create in VS2010 to use it. If i create a Win32 Console app without CLR’concurrency’ is not recognized and if i create Win32 Console app with CLR i get an error saying

Concurrency Runtime is not supported when compiling /clr.

#include "stdafx.h"
#include <ppl.h>
using namespace System;
void BubbleSort(int* input, int n)
{
    concurrency::parallel_for(0,n,[=](int y)
    {
        for(int k = 0; k< n - 1 -y; k++)
        {
            if(input[k]> input[k+1])
            {
                auto temp = input[k+1];
                input[k+1] = input[k];
                input[k] = temp;
            }
        }
    }
}
int main(array<System::String ^> ^args)
{
    Console::WriteLine(L"Hello World");


    return 0;
}

You can make a Win32 Console Application (no CLR). Once you #include <ppl.h>, the Concurrency namespace should be available. Note that it’s Concurrency::parallel_for (captial “C”).

For details, see the PPL example on MSDN.
