CLK_TCK undeclared on Mac

Question

#include <stdio.h>
#include <time.h>

clock_t start, stop;

int main(){
    start = clock();
    function();
    stop = clock();
    double duration = (stop - start)/CLK_TCK;
    return 0;
}

I got a problem in Xcode. CLK_TCK undeclared. how to fix it?

By using `CLOCKS_PER_SEC`? Please read the man page for `clock()`. — Weather Vane, Apr 27 '16 at 11:58
