Due at the end of lab.

Being able to find and fix errors in code, i.e. debugging, is clearly an important skill. For this lab you will need to debug a program that is full of errors. The program is here.

The goal of the program is to calculate the average value of a series of numbers entered by the user. First the user enters how many numbers to average. Then the user enters the individual numbers and the program is supposed to calculate the average of the numbers that were entered.

To correct the program you need to 1) fix any typos, 2) improve the variable names to make the code more readable, 3) fix the program's output so that it is more useful to the user, and 4) fix any logical errors so the program prints the correct answer.

Some suggestions to get started:

• There is an error on (almost) every line of code. Begin by reading through the code and trying to find the obvious typos.
• Try to understand the role of each line of code. Where it's helpful, give the variables more useful names and add comments so that you can keep track of what each line of code does.
• After you've done all of the above, try compiling the code and see how many errors you get. Try to fix the errors one at a time, starting with the first one. Recompile the code often to make sure you are removing errors, not adding new ones. It is a good idea to make copies of the program code as you make changes so that you can revert back to a prevous version of the code if your changes cause more errors.
• Once the code compiles, run it several times with different inputs to determine whether it is correctly calculating the average. There are likely still some logical errors that result in incorrect answers. Find and fix those. (Note: make sure to check the results when the average is an integer, e.g. average of 2, 3, 4, and when the average is a real number, e.g. average of 3, 3, 4.)

Turn in: A copy of the corrected program and sample output showing that it runs. Place your sample output in a file named Lab7output.txt. As always, if you cannot finish all of the functionality turn in as much as you complete - as long as your code compiles and runs. Turn in a copy of your program code and your Lab7output.txt file to Canvas.
