What should be the output of this program and why?

Question

#include <iostream>
using namespace std;
int main()
{
unsigned int a=23;
signed int b=-23;
if(a>b){
cout<<"True";
}
else{
cout<<"False";
}
}

Answer 1

output False.
because a is unsigned and b is signed. everytime you compare unsigned number with signed number , computer automatically cast signed to unsigned.Therefor,b become (2^32-23) bigger than a.

Answer 2

false bcoz - 23 is converted into unsigned automatically and hence it has much greater value than 23 hence it prints false

Answer 3

Should output False as 23 is not greater than 23, but is equal to. a >= b however, would output True.
