    This program will terminate for an input < 0 using this particular exit() function. Is there a function or a different statement to use that will loop back to the first cout statement so the user could input a new number? In this current form, the user has to re-execute the program after making a mistake.

    int p, k = 5;

    cout << "enter a number greater than or equal to 0" <<;
    cin >> p;
    cout << p + k;
    if (p < 0)
    cout << "error try again"
    exit(EXIT_FAILURE) ;

    Thanks for any comments!!

    yea, directly after the cout , do cin again instead of exiting. That would be a loop.
