// Function to compare two character strings
int compareStrings (const char s1[], const char s2[])
{
int i = 0, answer;
while ( s1[i] == s2[i] && s1[i] != '\0'&& s2[i] != '\0' )
++i;
if ( s1[i] < s2[i] )
answer = -1; /* s1 < s2 */
else if ( s1[i] == s2[i] )
answer = 0; /* s1 == s2 */
else
answer = 1; /* s1 > s2 */
return answer;
}

Answer 1

I need to convert the program above to use character pointers instead of arrays. Anybody have any ideas on how to do this?
