 * Andrei Florea  - CST 116 - Chapter 11 - Using input and output to work with files
 * 
 * I went over the Chapter 11 presentation, but I could not find any questions to answer.
 * 
 * 
* 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.

There is an additional line of what seems to be additional memory.

* 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.

Done, there was an issue in the for loop, as the index started at 0,
but it went one over than what it was supposed to.

* 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.

Done.

* 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.
*
