Header Comments

Writing a program involves combining a bunch of the techniques explained below, depending on your goal for the program. At minimum, your program file should contain a header with some basic information, and the description of your program. Headers are written using comments, and should include information like the file name, author, and a description of what the program does. It can have other information as well.

# file name:

# description: a program to calculate the area of a right triangle
