C - gettimeofday for computing time?

Question

do you know how to use gettimeofday for measuring computing time? I can measure one time by this code:

  char buffer[30];
  struct timeval tv;

  time_t curt         


        

Answer 1

If you want to measure code efficiency, or in any other way measure time intervals, the following will be easier:

#include 

int main()
{
   clock_t start = clock();
   //... do work here
   clock_t end = clock();
   double time_elapsed_in_seconds = (end - start)/(double)CLOCKS_PER_SEC;
   return 0;
}
