How many relational operators are commonly used in programming?

In programming, relational operators are used to compare two values or expressions, determining the relationship between them. The most commonly used relational operators include:

1. Equal to (==)

2. Not equal to (!=)

3. Greater than (>)

4. Less than (<)

5. Greater than or equal to (>=)

6. Less than or equal to (<=)

Since there are typically six relational operators used across various programming languages, the selection indicating that there are four is not sufficient to cover the complete set. While some languages may implement a slightly different syntax or may focus on fewer operators in specific contexts, the standard suite of relational operators in most programming environments includes all six mentioned. Understanding these operators is crucial, as they play a fundamental role in control structures like conditional statements and loops, allowing developers to create more dynamic and responsive applications.
