devry comp122 week 3 and week 4 discussions

This week’s lecture discusses the different types of repetition situations and how they are controlled. Let’s start out by discussing some simple example problems where you see the need for repetition. Is the repetition in your example count controlled, or would it be controlled by some sort of condition? Which type of loop would you choose for your example and why?

Loops can be tricky and can cause errors in the program containing them. The trick is to get the loop to execute its body the correct number of times. Let’s discuss how to figure out how many times a loop will execute its body. Give an example of a count controlled loop structure, explain how you determine the number of times it will execute its body. How will you determine the number of times a conditional controlled loop with a sample input set executes its body?\

This week we are examining techniques for debugging and testing a program. Let’s start off the week by discussing how to debug a program that compiles and links correctly, contains both selection and repetition statements, but does not generate correct output results. What techniques would you use to try to determine where the problems are in the program?

The Midterm is this week. The Midterm covers all the material from the first 3 weeks of the course. Look back over the reading materials, homework, and labs from the first 3 weeks. The language summary documents can be a good source of review information about the specifics of C++. Use this thread to ask any questions that you have regarding anything you are uncertain about. If you don’t have a specific question, post some things you have observed about the programming process or about using C++.
