Hello C++: Variables

At the end of this lesson you will know what a variable is and how to use them in a program. You will be able to write a program that will input values, perform a simple calculation and output the result.

1. Print and read the lesson. (Punch, staple, put in your binder.) Variables

2. Do the online tutorial: basic:

3. Run each of the programs from the lesson:

To get the most out of these programs

Copy the program, paste it into your C++ compiler and run it.
Experiment with it: make little changes and see what happens, make sure you understand it.
Erase it - now try to write it without looking at your notes!

4. Using the sample programs as a model, write a program to do some other calculation. Follow good programming habits:

Indent each statement inside the curly braces about 2 spaces. All of the statements should line up.
Use good variable names and comments: if you look at the program in a year, will you know what the program does?
