๐ Topic Summary
Complex conditional expressions allow you to combine multiple conditions in your code, making it more powerful and flexible. Instead of just checking one thing at a time, you can check several conditions together using logical operators like AND, OR, and NOT. This helps you create code that can handle a wider range of situations and make more nuanced decisions.
For example, you might want to check if a student's score is both greater than 70 and if they've completed all their assignments before assigning them a passing grade. Complex conditionals are essential for creating sophisticated programs that can adapt to different inputs and scenarios.
๐ค Part A: Vocabulary
Match the terms on the left with the correct definitions on the right:
| Term |
Definition |
| 1. Conditional Statement |
A. A logical operator that returns `true` if at least one of the operands is `true`. |
| 2. Boolean Expression |
B. A programming construct that allows different code to be executed based on whether a condition is true or false. |
| 3. AND Operator |
C. A value that can be either `true` or `false`. |
| 4. OR Operator |
D. An expression that evaluates to either `true` or `false`. |
| 5. Boolean |
E. A logical operator that returns `true` only if both operands are `true`. |
(Answers: 1-B, 2-D, 3-E, 4-A, 5-C)
โ๏ธ Part B: Fill in the Blanks
Complete the following paragraph using the words provided below:
Words: `Boolean`, `true`, `false`, `AND`, `OR`
A complex conditional expression relies on _______ logic. The result will be either _______ or _______. The _______ operator requires both conditions to be _______ for the overall expression to be _______. Conversely, the _______ operator only needs one condition to be _______ for the entire condition to be _______.
(Answers: Boolean, true, false, AND, true, true, OR, true, true)
๐ค Part C: Critical Thinking
Imagine you are writing a program to determine if a student is eligible for a scholarship. The requirements are that the student must have a GPA of 3.5 or higher AND have volunteered for at least 50 hours. Write a complex conditional expression (in pseudocode or any programming language you are familiar with) that checks if a student meets both of these requirements. Explain how your expression works.
