Thread: Quick Newbie String Help

I have an assignment in C where I need to create a function to compare 2 strings to see if they are equal without using any of the standard library functions for strings. I have the following so far.

Code:

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

int equals(char,char);

int main(void){

char s1[] = "PRINT";
char s2[12];

(void)scanf("%s",s2);

if(equals(s1,s2) == 1)
printf("s2 = PRINT");
else
printf("s2 != PRINT");

}

How would I create the equals function?

By walking along the arrays simultaneously and comparing each char of s1 with each char of s2 in turn until end of string (NULL) is reached.
