-- How to introduce a pause in your C++ program --

 I often get asked by my students how to introduce a pause on their C++ program, the problem is that depending of the IDE you are using, after your program executes is closes the command line window automatically, so here are my 2 favorite approaches.

 Windows Operating System

#include <iostream>

#include <cstdlib>

using namespace std;

int main()

{

    cout << "Please press any key to continue";

    system("pause");

    return 0;

}

If you are using either Linux / Unix unfortunately the pause command does not work, but you can use something like this

#include <iostream>

#include <cstdlib>

using namespace std;

int main()

{

    cout << "Please press any key to continue";

    cin.ignore();

    return 0;

}
