    Quick question

    I have a program for class, and I need to implement a timer, just like a stopwatch, time the milliseconds between displaying something and the user inputting something. Someone told me to call gettimeofday() twice and take the difference. I don't know how to implement that though. Any other ideas?

    Maybe you would be interested in the standard function clock().

    Note also that using successive reads of "current time" [whichever variant of such function you use] is wasteful - there are functions in all modern OS's to perform some sort of delay, such as usleep() in Linux and Sleep() in Windows.
