Variables in Alice 3

Module 09: Variables in Alice 3

A variable is a named location in memory. In this module, you will learn about variables and how to use them.
Your program will declare variables, assign them values, then use them in your code.

Goals:

• Learn about variables and how to use them
• Declare variables
• Assign them values

Objectives:

• Name the different types in Alice.
• Name variables and objects correctly.
• Declare a variable and give it an initial value.
• Use the assign statement to give a variable a new value.
• Select and use functions to ask the user a question and store the result.
• Experiment with the tools available in Alice3.
• Use constants appropriately.
