// How to COMPARE STRINGS
// - Use standard library function strcmp(…).
// - You will need #include <string.h> at the top of your file.
// - REMEMBER:  strcmp(…) return ZERO (0) if the strings are the SAME (i.e., same characters)

int main(int argc, char* argv[]) {
    char s1[] = "apples";
    char s2[] = "oranges";
    char s3[] = "apples";
    if( strcmp(s1, s2) ) {  // compare s1 and s2  // BUG!!!!!!!!!!!!
        printf("s1 and s2 contain the same characters.\n");
    }
    else {
        printf("s1 and s2 do NOT contain the same characters.\n");
    }

    if( strcmp(s1, s3) ) {  // compare s1 and s3  // BUG!!!!!!!!!!!!
        printf("s1 and s3 contain the same characters.\n");
    }
    else {
        printf("s1 and s3 do NOT contain the same characters.\n");
    }
    return EXIT_SUCCESS;
}
