+* File: CST116-Ch10-Debugging.cpp
+*
+* General Instructions: Complete each step before proceeding to the
+* next.
+*
+* Debugging Exercise 1
+*
+* 1) Build and run the program.
+* 2) Examine the code and the output and notice the use of
+* parallel arrays.
+* 3) Insert breakpoints at Breakpoint 1, Breakpoint 2, and Breakpoint
+* 3.
+* 4) Run to Breakpoint 1.
+* 5) Place a watch on varX, varY and varZ. Click on the '+' in the
+* watch window to see the individual elements associated with each
+* of the arrays.
+* 6) Continue running your program to Breakpoint 2.
+* 7) Add a watch on the array called name. Again, click on the '+'
+* symbol. Notice how a multidimensional array is shown in the
+* debugger, the null terminating characters location, and how a
+* character is represented within each element of the array.
+* 8) Continue running the program to Breakpoint 3.
+* 9) Notice the contents of varX and varY now that you are back in the
+* main function.
+* 10) Clear all the breakpoints.
+* 11) Stop debugging.
+*
+* Debugging Exercise 2
+*
+* 1) Change the constant SIZE from 5 to 10.
+* 2) Change any literal containing a 5 to the constant SIZE.
+* Notice the usefulness of the constant when changes need
+* to be made to your code.
+* 3) Set a breakpoint at Breakpoint 4. Now on this breakpoint
+* set the necessary condition so the loop breaks when x hits 8.
+* (Hint: If you need help setting breakpoints based upon a
+* condition refer to Chapter 8).
+* 4) Run to Breakpoint 4.
+* 5) Continue stepping into the remainder of the for loop until the
+* flow returns back to main.
+* 6) Make sure your Watch window is visible and notice the contents
+* of varY and varZ now that you are back in main.
+* 7) Stop debugging.
+* 8) Disable all breakpoints.
+* 9) Rebuild and execute the program and verify the results.
+*
+* Debugging Exercise 3
+*
+* 1) Just before the call to the PrintFunction in main, add an
+* assignment statement to change the first element in the
+* array varZ to -99.
+* 2) Build and execute your code, verifying that the calculations
+* are correct in relation to element 0 of varZ.
+* 3) Add a line to assign the contents of the second element of
+* varX to 99 in FunctionTwo.
+* 4) Rebuild your program.
+* 5 Obviously there is a problem. Remove the const from the
+* function declaration and header for varX.
+* 5) Now you should be able to build and execute your code. Do it.
+* 6) Set a breakpoint on Breakpoint 2.
+* 7) Re-enable Breakpoint 2.
+* 8) Run to Breakpoint 2 and make sure you have a watch on the
+* variable name.
+* 9) Click on the '+'. Once you see all the elements
+* within the array, change the 'Value' (in the Value field)
+* for the first element of the array directly within the Watch
+* window to the character 'Z'. Notice how the value is updated
+* by displaying the new ASCII value too.
+* 10) Stop debugging.
+* 11) Disable all breakpoints.
