* File: Chapter 11 Debug.cpp
*
* General Instructions: Complete each step before proceeding to the
* next.
*
* Debugging Exercise 1
*
* 1) Make your own data file like Troy 12, with the next person on the
*    next line and save it to a directory you create on your drive.
* 2) Under the Project menu, select Add Existing Item and
*    add the input file you just placed on your drive to your
*    current project. Make sure your Solution Explorer window
*    is visible. If not, you can display it by selecting Solution
*    Explorer (or Ctrl+Alt+L).
* 3) Open the input file by simply double clicking the name of the
*    file in your Solution Explorer.
* 4) Build and execute the program.
* 5) Update the file paths below to correctly represent the path you
*    created.
* 6) Rebuild and execute the program.
* 7) Examine the code and the output and notice the use of
*    parallel arrays.
* 8) Add the output file created via the execution of
*    your program to your Project.  Execute your program again
*    and notice how Visual Studio has rewritten your output file
*    and asks if you would like to reload the file (select Yes).
* 9) Examine the contents of both the input and the output file.
* 10) Fix all the problems in your code that exist in relation to
*     the output. Verify that your output is appropriate for your
      input file.
* 11) Build and execute your code until you have all errors
*     removed and all the output is correct.
*
* Debugging Exercise 2
*
* 1) Replace the double slashes (\\) in the input file open statement
*    with only a single slash
*    (i.e., inFile.open("C:\TEMP\Chap_11_data.txt").
* 2) Build your code, noticing the impact of the invalid path you
*    created in the previous step.
* 3) Replace the backslashes as they were.
* 4) Change both the input and output filenames so they are
*    invalid.
* 5) Update the file related error messages within the code
*    to also provide the specific name of the file that is having a
*    problem.
* 6) Rebuild and execute your program to verify that your messages
*    are correct.
* 7) Correct the path names.
* 8) Build and execute your code and carefully check your
*    output on both the console and in the output file.
