Khan Academy: Procedures With Return Values

Procedures can compute values for the rest of the program to use by sending back return values.

Practice using return values from procedures in computer programs.

Practice defining procedures with parameters for programs in the AP CSP pseudocode, in this set of free practice questions designed for AP Computer Science Principles students.

Practice using procedures with parameters for computer programming.

When programming, we use procedures to make our code more reusable and to better organize our code. Often-times, we pass parameters to a procedure so that we can change the output of the code.

In this video [2:49] we take a slightly different approach to understanding the difference between real and nominal values: find the value of an asset in a previous year's dollars.
