You need to either run your program from the command prompt, or put some form of pause at the end of your program.
using namespace std;
// This is my program
cout << "Hello world!\n\n\n";
// This keeps the console window open on Windows.
cout << "Press ENTER to quit." << flush;
cin.ignore( numeric_limits <streamsize> ::max(), '\n' );
