C++11: Initializer lists

You can get the size of an initializer list with the size() member function. Here is an example:

#include

#include

using namespace std;

int main()

 {

    initializer_list myInitializer_List;

    myInitializer_List = {10, 11, 12};

    cout << myInitializer_List.size() << endl;

    return 0;

}

// output: 3
