Performance Testing In C

Question

Is there an easy-to-use function to do simple performance tests here on Sololearn?

I read that time() isn't precise enough for that...

Answer 1

ChillPill , did you have a code here for timing functions?

Answer 2

I found this which check the time taken for a function
#include <time.h>

clock_t start, end;
double cpu_time_used;

start = clock();
... /* Do the work. */
end = clock();
cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC;

Answer 3

*AsterisK*, clock, like time, seems to only return seconds but not milliseconds.

I wonder if there's anything else...

Answer 4

HonFu I tested with 4 methods(except time()), sadly none worked here🤔

and FYI: clock doesn't return seconds but somehow SL servers behave that way…
