What is a Variable?

A named storage location in memory.

What are Data Types?

Categories of values (e.g., integer, string, boolean).

What is a List?

An ordered collection of elements.

What is an Element?

An individual value in a list.

What is an Index?

The position of an element in a list.

What is an Algorithm?

A step-by-step procedure for solving a problem.

What is Sequencing?

Executing code statements in order.

What is a Boolean Value?

A value that is either true or false.

What is Iteration?

Repeating a block of code.

What is a Procedure?

A named block of code that performs a specific task.

What is the value of x? x ← 5 x ← x + 2

7

What is the value of myList[2]? myList ← [10, 20, 30, 40]
