// Using memcmp()

#include <stdio.h>

#include <string.h>

int main(void)

{

char s1[] = "ABCDEFGHIJK", s2[] = "ABCDXYZPQR";

printf("Using memcmp()\n");

printf("--------------\n");

printf("s1 = %s\n", s1);

printf("s2 = %s\n", s2);

printf("\nmemcmp(s1, s2, 4) = %2d\n", memcmp(s1, s2, 4));

printf("memcmp(s1, s2, 7) = %2d\n", memcmp(s1, s2, 7));

printf("memcmp(s2, s1, 7) = %2d\n", memcmp(s2, s1, 7));

return 0;

}

Output example:

Using memcmp()

--------------

s1 = ABCDEFGHIJK

s2 = ABCDXYZPQR

memcmp(s1, s2, 4) = 0

memcmp(s1, s2, 7) = -1

memcmp(s2, s1, 7) = 1
