#include<stdio.h>
int str_cmp(const char *s1, const char *s2)
{
unsigned int i = 0, diff;
while(*(s1+i) && *(s2+i))
{
diff = (*(s1+i)-*(s2+i));
if(!diff)i++;
else break;
}
return diff;
}
int main()
{
printf("chuma %d ", str_cmp("abcd","abcde"));
return 0;
}
U can use this as a prototype and enhance this. I havent
even tried compilng this.

You are to write your own versions of strcpy() and strlen (). Call them mystrcpy() and mystrlen(). Write them first as code within main(), not as functions, then, convert them to functions. You will pass two arrays to the function in the case of mystrcpy(), the source and target array.
