Question

#include<stdio.h>
int main() {
if(sizeof(int) > - 1)
printf("Yes");
else
printf("No");

Answer 1

Because sizeof(int) returns unsigned int(that is positive integers) and it makes no sense comparing unsigned int with signed(negative integers), so its false.

hence No is printed.

Answer 2

As RKK said, sizeof returns unsigned int. While comparing unsigned int to signed int, signed implicitly converts to unsigned. -1 converts to unsigned is 2^32-1. Thus the comparation returns false.
