How to compile the code using #include

Question

I am trying to compile some C++ code that uses threads:

#include 
#include 
void hello()
{
    std::cout<<\"Hello Concurr         


        

Answer 1

and standard threading support is a new feature (defined in the C++11 standard). As for g++, you have to enable it adding -std=c++0x to the command line, as explained in the error message.

Also, you are using a nonstandard (Microsoft-specific) main, use the "classic" main and normal char:

// thread1.cpp
#include 
#include 

void hello()
{
    std::cout<<"Hello Concurrent World\n";
}

int main(int argc, char * argv[])
{
    std::thread t(hello);
    t.join();

    return 0;
}

Notice that not all C++11 features are available in current compilers; as far as g++ is concerned, you can find the status of their implementation here.
