Step 1 : Open 'Run' in the START menu.
Step 2 : Type 'cmd' in the run tab.The command prompt will appear.
Step 3 : Type 'ipconfig' and press ENTER.

#include <iostream>

using namespace std;
int main()
{
    system("C:\\Windows\\system32\\ipconfig");
    cin.get();
    return 0; // halts the program until enter is pressed
} // end of main
