how to view time in c code example

Example 1: c get time

/* localtime example */
#include <stdio.h>
#include <time.h>

int main ()
{
  time_t rawtime;
  struct tm * timeinfo;

  time ( &rawtime );
  timeinfo = localtime ( &rawtime );
  printf ( "Current local time and date: %s", asctime (timeinfo) );
  
  return 0;
}

Example 2: measure time in c

void timeWait (float threshold) {
    float timeInitial, timeMeasured, timeDelta = 0;

    timeInitial = (float)clock();
    while (timeDelta < threshold) {
        timeMeasured = (float)clock();
        timeDelta = ((timeMeasured - timeInitial) / (float)CLOCKS_PER_SEC);
    }
    printf("%.2f - %.2f s have passed.", threshold, timeDelta);
}
