Storing and Changing Information in a Program


Now that you have been introduced to variables and expressions, you can give a wide range of instructions to your computer in a program. With the skills you have developed during this hour, you can write programs that accomplish many of the same tasks as a calculator, handling sophisticated mathematical equations with ease.

Numbers are only one kind of thing that can be stored in a variable. You also can store characters, strings of characters, and special true or false values called boolean variables. The next hour will expand your knowledge of String variables and how they are used.
