Passing Arguments and Return Values

When you write a procedure (like a function in C), it often needs data to work with, and it might produce a result.

This lesson explores how data, called arguments, is sent into a procedure, and how the procedure sends a return value back out.

Procedures are like mini-programs. To make them useful, they need to communicate with the main program or other procedures.

• Arguments: Input data for the procedure to process.
• Return Value: The result produced by the procedure.

Without this communication, procedures would be very limited!
