1. What is a variable in programming?

A) A way to repeat code B) A container for storing data C) A type of loop D) A debugging tool

Variables let you store information in your program and refer to it later. Think of them as labeled boxes for your data.

2. Which symbol is used for assignment in most languages?

A) == B) : C) = D) ->

The equals sign = assigns a value to a variable. For example: x = 5.

3. What does an if statement do?
