Question

Iteration
Sequencing
Selection

Answer 1

The code you provided involves several programming concepts. Let's break it down:

1. Sequencing: This refers to executing statements in order. In your code, the statements are executed in sequence: first, the program prompts for the first name, then for the last name, and finally prints the greeting.

2. Iteration: This refers to repeating a block of code. Your code does not include any loops or repeated actions, so it does not utilize iteration.

3. Selection: This involves making decisions in the code, typically using conditional statements (like if, else, etc.). Your code does not contain any decision-making structures, so it does not use selection either.

Conclusion:

Your code primarily demonstrates sequencing. It does not utilize iteration or selection.
