// 13c - 11.13 Debugging Exercises
/*

// 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		// Just used the same paths as they followed what I was doing
//    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.

// Removed #includes and put them at top of file
