clock_t 를 이용한 c프로그램 시간측정

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

int main()
{
        clock_t start, end;

        int i, sum;
        sum = 0;

        start = clock();
        for( i = 0 ; i < 10000000 ; i++)
                sum+=1;

        end = clock();
        printf("%d, time = %f\n", sum, (double) (end - start)/CLOCKS_PER_SEC);

}
