Lesson 1.7 Commenting Your Code

Description

In this lesson, students will learn how to utilize comments in their code to explain what their code is doing. Comments should include preconditions and postconditions. Preconditions are assumptions we make about what is true before a function is called in our program. Postconditions are what should be true after a function is called in our program.


Objective

Students will be able to:

  • Explain the preconditions and postconditions of a function
  • Create clear and readable comments in their code that help the reader understand the code
  • Explain the purpose of comments
