Hello Computer Science: C++ Functions

Prepare today for the demands of tomorrow.

At the end of this lesson you will know what a function is and how to use it in a program. You will be able to write a program that will use functions.

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

2. Run each of the programs from the lesson, work with the flowchart if one is provided:
Area: uses a function to find area
Odd and Even numbers
Shipping: the Speedy Reliable shipping problem
Sort 3: sorts 3 numbers using pass by reference Flowchart1, Flowchart 2 (Very important!)
Grades: uses functions for letter grade, etc. Flowchart
Payroll: uses separate functions for several calculations.

To get the most out of these programs

• Run the flowchart (if provided) to help understand the logic.
• 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!
