#include <stdio.h> #include <string.h> int main() { char s[1001]; fgets(s, 1001, stdin); for (int i = strlen(s) - 1; s[i] == '\n'; i--) ; for (; i >= 0; putchar(s[i--])) ; } return 0; }

The code reads a line of input, then attempts to remove the trailing newline and print the string in reverse. However, there is a problem with the variable scope and the loop logic.

- The variable `i` is declared inside the first `for` loop, so it is not accessible in the second `for` loop. You need to declare `i` before the loops so both can use it.
- The first loop condition `s[i] == '\n'` will only run if the last character is a newline, but the loop decrements `i` and checks again, which may go out of bounds if there is no newline. Think about how to correctly find the last character index before the newline.
