1. Class 4: Repetition Pretest Posttest Counting Flowchart these!
Condition tested before block of code to repeat
If condition is false initially, the block never executes
Posttest
Condition tested after block of code to repeat
Block of code will always execute at least once
Counting
Repeat for a specified number of times
Flowchart these!

2. Last Class Tomorrow: Show Time!
Using the overhead, demonstrate your project:
Show your design in the form of pseudocode, flowcharts, and a verbal description of your goal.
Show your code - each method which will contain comments describing the task of each method.
Demonstrate your program by running it a few times.
Answer questions from the audience (us).
Audience will make suggestions for improving your project.
You will be required for the final exam, which will be on July 25, to describe how you improved your program.
You will also be required to implement improvements for the final demonstration on July 25.
