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
", sizeof(x == y)); printf("%d
", sizeof(x < y)); return 0; } |
Output:
4 4
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:
1 1
