Loop ErrorsTo gain more practice with loops, as
well as provide experience to read/fix someone else's code.
You will learn how the flow of control
can be altered with different types of looping statements. You'll see
the effect of braces in creating blocks of code, consider how complex
boolean expressions are evaluated, and witness common pitfalls in
programming conditional looping statements.
Your task for this lab is to fix a
program that has several loops and several errors.
Instructions
Create a new project and call it Lab04B. Once you have your empty
main.cpp
, open LoopErrors_main.cpp and copy the code to
your
main.cpp
.
This LoopErrors_main.cpp program, as it
currently stands, contains a number of errors related to the learning
objectives stated. Your task is to correct the program, describe the
type of error(s) you found, and list all the different values you need
to input to test all possible cases in each section of the program. You
should write this information (errors found/corrected and test values)
as a comment at the top of each program section.
Compile and run the program. It is
obviously not correct!
For each section, you must correct the
error or errors. To identify the errors, you may need to do some
calculations. For example, if the program says it is calculating the
sum of the numbers from 1 to 5 (inclusive), the result should be 15.
The program contains some sections
with infinite loops. Some infinite loops will cause a message to keep
scrolling on your screen. For others, the cursor will just be blinking
and nothing will appear (at least immediately) on your screen. Clicking
on the X in the upper right of console window will break out of an
infinite loop. You might want to challenge yourself to identify the
infinite loops before you try to run the program. But running the
program to see where the infinite loops occur is also acceptable.
NOTE: If you get help on any of these
sections, BE SURE that you understand the answer. You may see questions
similar to these on the exam.
Lab Submission
You will submit your solution to this lab with the rest of Week04.
Detailed instructions for doing this are posted in Assignment 04.
