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++.

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.

Sorry donna I didn't kniw that my code's setting I edit it as a public but I think Babak has solved the problem

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

You wrote aa and aaa as an example it will work for jdhddj and jshdr ?

Can't we write this program in C ?This is my homework and I want to compare the letters of two words
0
Sample output:
Enter your string :welcome
Enter your string :goodbye
O
Like this
0
No just number of letters
0
When the two word are equal number of letters I wanna print them to screen 0
0
When the number of first word greater than second I wanna print them to screen 1
0
When the number of second word greater than first one I wanna print to screen -1
0
Could I explain ?

If I change switch case section as this it will be true ?
