+/********************************************************************
+* 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.
