Question

IF (timer <= 0) OR (numberOfLives == 0):     PRINT "Game Over"This code uses:IterationSequencingSelection

Answer 1

The code snippet you've provided demonstrates a conditional statement that determines whether to print "Game Over." Let's analyze the elements involved in your code.

1. **Iteration**: This typically refers to the repetition of a set of instructions until a certain condition is met. Your snippet does not include any loops (like `for` or `while`), so it does not involve iteration.

2. **Sequencing**: This is the general flow of statements executed in a specific order. In your snippet, the condition is checked, and if it evaluates to true, the action is taken (printing). So, there is a basic element of sequencing involved.

3. **Selection**: This involves making decisions based on certain conditions. The `IF` statement in your code is a classic example of selection, where the program decides to execute the `PRINT` statement only if one of the two conditions is true (`timer <= 0` or `numberOfLives == 0`).

Based on this analysis, the code snippet primarily uses **selection** to determine whether to display "Game Over." There is also an element of **sequencing**, but it does not utilize **iteration**.

So, in summary:
- **Selection**: Yes
- **Sequencing**: Yes
- **Iteration**: No
