You want a delay of 1 minute ?

You can use the standard library for that, something like below (note that it's a busy wait, so likely not the preferred way to do it).

Or you can use platform dependent functionality, like sleep or usleep (Linux), Sleep (Windows), ...
What platform are you on ?
time_t tstart = time(0);
time_t tend = time(0);
while (difftime(tend, tstart) < 60.0f) {   // <--- one minute
  // busy wait
}

The code sample should have been like this of course (otherwise you'd likely have an infinite loop) :
time_t tstart = time(0);
time_t tend = time(0);
while (difftime(tend, tstart) < 60.0f) {   // <--- one minute
  // busy wait
  tend = time(0);
}
