# 3.8 Equality Operators

Equality operators are relational operators used to compare two values. They determine whether two operands are equal or not equal and produce a Boolean result. The result of an equality comparison is either `true` or `false`.

The equality operator (`==`) checks whether two operands have the same value, while the inequality operator (`!=`) checks whether the operands have different values.

## Source Code

```
#include <iostream>

int main()
{
    int num1 = 25;
    int num2 = 30;

    std::cout << "num1 == num2 : " << (num1 == num2) << '\n';
    std::cout << "num1 != num2 : " << (num1 != num2) << '\n';

    return 0;
}
```

## Output

```
num1 == num2 : 0
num1 != num2 : 1
```

## Explanation

- The equality operator (`==`) compares two operands and returns `true` if their values are equal.
- The inequality operator (`!=`) compares two operands and returns `true` if their values are different.
- Both operators produce a Boolean result of type `bool`.
- By default, `std::cout` displays Boolean values as `1` for `true` and `0` for `false`.
- Parentheses are used around the comparison expressions to improve readability.
- Equality operators compare values and do not modify either operand.
- `return 0;` terminates the program successfully.
