Question

What types of relationships between values can you test with relational operators?

Short answer

Answer: The six common relational operators are equal to (==), not equal to (!=), less than (<), greater than (>), less than or equal to (<=), and greater than or equal to (>=). They test if values are equal, not equal, less than, greater than, less than or equal to, and greater than or equal to each other, respectively.

Step-by-step solution

1. Equal to (==) operator

The equal to (==) operator checks if the two values being compared are the same or not. It returns true if the values are equal and false if they are not. For example: (3 == 3) is true, while (4 == 5) is false.

2. Not equal to (!=) operator

The not equal to (!=) operator checks if the values being compared are different. It returns true if the values are not equal and false if they are equal. For example: (3 != 4) is true, while (5 != 5) is false.

3. Less than (

The less than (<) operator checks if the left value is smaller than the right value. It returns true if the left value is indeed less than the right value and false if it is not. For example: (3 < 5) is true, while (6 < 3) is false.

4. Greater than (>) operator

The greater than (>) operator checks if the left value is larger than the right value. It returns true if the left value is indeed greater than the right value and false if it is not. For example: (4 > 2) is true, while (2 > 3) is false.

5. Less than or equal to (

The less than or equal to (<=) operator checks if the left value is smaller than or equal to the right value. It returns true if the left value is either less than or equal to the right value and false if it is greater. For example: (3 <= 5) is true, (5 <= 5) is true, and (6 <= 3) is false.

6. Greater than or equal to (>=) operator

The greater than or equal to (>=) operator checks if the left value is larger than or equal to the right value. It returns true if the left value is either greater than or equal to the right value and false if it is less. For example: (4 >= 2) is true, (2 >= 2) is true, and (2 >= 3) is false.
