Logical operators are the building blocks of decision-making in computer science. They allow us to combine or modify boolean expressions (true or false) to create more complex conditions. In AP Computer Science Principles (CSP), understanding AND, OR, and NOT is crucial for writing effective code that responds to different situations.
Think of them like this: AND requires all conditions to be true, OR requires at least one condition to be true, and NOT reverses the truth value of a condition. Mastering these operators will significantly improve your ability to control the flow of your programs and solve problems logically. Let's dive in!
Match each term with its definition:
| Term | Definition |
|---|---|
| 1. AND | A. Reverses the truth value of an expression. |
| 2. OR | B. An expression that evaluates to either true or false. |
| 3. NOT | C. Returns true if at least one of the conditions is true. |
| 4. Boolean Expression | D. Returns true if both conditions are true. |
| 5. Truth Table | E. A table showing all possible input values and the corresponding output for a logical operator. |
