Question

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

Short answer

Question: What are the different types of relationships between values that can be tested using relational operators, and provide brief examples for each operator. Answer: Relational operators are used to test relationships between values. Common relational operators are: 1. Greater than (">"): Evaluates if a value is larger than another value. Example: 5 > 3 returns true, as 5 is greater than 3. 2. Less than ("<"): Determines if a value is smaller than another value. Example: 3 < 5 returns true, as 3 is less than 5. 3. Greater than or equal to (">="): Tests if a value is greater than or equal to another value. Example: 5 >= 5 returns true, as 5 is equal to 5. 4. Less than or equal to ("<="): Checks if a value is less than or equal to another value. Example: 3 <= 5 returns true, as 3 is less than 5. 5. Equal to ("=="): Tests if two values are equal. Example: 5 == 5 returns true, as both values are the same. 6. Not equal to ("!="): Determines if two values are not equal. Example: 5 != 3 returns true, as the values are not the same.

Step-by-step solution

1. Introduction to Relational Operators

Relational operators are used to test the relationships between two values. These operators return either true or false based on the condition being evaluated. Common relational operators include greater than (">"), less than ("<"), greater than or equal to (">="), less than or equal to ("<="), equal to ("=="), and not equal to ("!=").

2. Greater Than Operator (">")

The greater than operator (">") is used to test if a value is larger than another value. For example, the expression 5 > 3 returns true, as 5 is greater than 3.

3. Less Than Operator ("

The less than operator ("<") is used to determine if a value is smaller than another value. For example, the expression 3 < 5 returns true, as 3 is less than 5.

4. Greater Than or Equal To Operator (">=")

The greater than or equal to operator (">=") tests if a value is either greater than or equal to another value. For example, the expression 5 >= 5 returns true, as 5 is equal to 5.

5. Less Than or Equal To Operator ("

The less than or equal to operator ("<=") checks if a value is less than or equal to another value. For example, the expression 3 <= 5 returns true, as 3 is less than 5.

6. Equal To Operator ("==")

The equal to operator ("==") is used to test if two values are equal. For example, the expression 5 == 5 returns true, as both values are the same.

7. Not Equal To Operator ("!=")

The not equal to operator ("!=") determines if two values are not equal. For example, the expression 5 != 3 returns true, as the values are not the same. In summary, relational operators help us test various relationships between values, such as greater than, less than, greater than or equal to, less than or equal to, equal to, and not equal to.
