Can someone recover this code ?

I can not understand how can check a and b to print them the screen ? https://code.sololearn.com/cMg1WqhqJS7C/?ref=app

#include <stdio.h> int compareString(char *first, char *second) { int a = 0, b = 0, result = 0; while (*first != '\0') { first++; // just address increment a++; } while (*second != '\0') { second++; // just address increment b++; } if (a == b) { result = 0; } else if (a < b) { result = -1; } else if (a > b) { result = 1; } return result; } int main() { char first[1000], second[1000]; printf("Enter your string :\n"); gets(first); printf("Enter your string :\n"); gets(second); switch (compareString(first, second)) { case -1: printf("first < second\n"); break; case 0: printf("first == second\n"); break; case 1: printf("first > second\n"); break; } return 0; } Sample outputs: Enter your string : aa Enter your string : aaa first < second Enter your string : aaa Enter your string : aa first > second Enter your string : aa Enter your string : aa first == second

The length differences just count. It doesn't take into account the difference in letters. In fact the above function acts like std::string::compare() in C++. https://en.cppreference.com/w/cpp/string/basic_string/compare

It's possible, indeed.

Enter your string :welcome Enter your string :goodbye The length of both strings is 7 But the letter `w` has higher ASCII value compare to `g` So, first string > second string Is this what you are looking for?

You can simply replace the `printf`s texts with your favorite replacement like this: switch (compareString(first, second)) { case -1: printf("-1\n"); break; case 0: printf("0\n"); break; case 1: printf("1\n"); break; }

Or even simpler printf ("%d", compareString(first, second));

Yes, because all you need to know is the integer result of the comparison, a single `printf` statement as above would be sufficient. It prints out `-1` when first < second `0` when first == second `1` when first > second as simple as that.

Does it work for just same characters or could it work for different ones ?
