Answer / lylez00

#include <string.h>
/* strcmp */
int (strcmp)(const char *s1, const char *s2)
{
unsigned char uc1, uc2;
/* Move s1 and s2 to the first differing characters
in each string, or the ends of the strings if they
are identical. */
while (*s1 != '\0' && *s1 == *s2) {
s1++;
s2++;
}
/* Compare the characters as unsigned char and
return the difference. */
uc1 = (*(unsigned char *) s1);
uc2 = (*(unsigned char *) s2);
return ((uc1 < uc2) ? -1 : (uc1 > uc2));
