C++ Comparison Operators

Comparison operators in C++ are used to compare two values or expressions. They return a boolean value (true or false).

List of Comparison Operators

Operator	Description	Example
==	Equal to	5 == 5 // true
!=	Not equal to	5 != 3 // true
>	Greater than	7 > 5 // true
<	Less than	3 < 7 // true
>=	Greater than or equal to	5 >= 5 // true
<=	Less than or equal to	4 <= 5 // true

Example Program

#include <iostream>
using namespace std;

int main() {

    int a = 10;
    int b = 5;

    cout << "a == b: " << (a == b) << endl;
    cout << "a != b: " << (a != b) << endl;
    cout << "a > b: " << (a > b) << endl;
    cout << "a < b: " << (a < b) << endl;
    cout << "a >= b: " << (a >= b) << endl;
    cout << "a <= b: " << (a <= b) << endl;

    return 0;
}

Output

a == b: 0
a != b: 1
a > b: 1
a < b: 0
a >= b: 1
a <= b: 0

Important Notes

Comparison operators always return true (1) or false (0).
They are commonly used in if statements, loops, and conditional expressions.
Parentheses are often used to ensure correct evaluation of expressions.
