Thanks in advance,

for processor time use clock() gives the best approximation.
for calendar time use time() and difftime().

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

int main(void) {
    int i;
    time_t start,end;
    clock_t cend;

    if((start = time(NULL)) == (time_t)-1) exit(EXIT_FAILURE);
    for(i = 0;i < 400;i++) puts("Hello World");
    if((cend = clock()) == (clock_t)-1) exit(EXIT_FAILURE);
    if((end = time(NULL)) == (time_t)-1) exit(EXIT_FAILURE);
    printf("Elapsed processor time is: %.2fsec\n",
        (double)cend / CLOCKS_PER_SEC);
    printf("Elapsed calendar time: %.2fsec\n",difftime(end,start));
    return 0;
    }
