Results of comparison operations in C and C++

In C, data type of result of comparison operations is int. For example, see the following program.

#include<stdio.h> 
int main() 
{ 
    int x = 10, y = 10; 
    printf("%d \n", sizeof(x == y)); 
    printf("%d \n", sizeof(x < y)); 
    return 0; 
}

Output:

Whereas in C++, type of results of comparison operations is bool. For example, see the following program.

#include<iostream> 
using namespace std; 
  
int main() 
{ 
    int x = 10, y = 10; 
    cout << sizeof(x == y) << endl; 
    cout << sizeof(x < y); 
    return 0; 
} 

Output:
