+* File: CST116-Ch9-Debugging.cpp
+*
+* General Instructions: Complete each step before proceeding to the
+* next.
+*
+* Debugging Exercise 1
+*
+* 1) Insert a breakpoint on the lines indicated in the code.            Done
+* 3) Place a watch on age and days.                                     Done
+* 4) Add another watch using &age for the name. This will display   
+*    the address of age.                                                Done
+* 5) Write down the address of age.                                     0x001df6e4{0}
+* 6) Step Into the code for the function GetAge.                        Done
+* 7) The execution continues to the function header for GetAge.         Yes, it did.
+* 8) Step into one more time.                                           Done
+* 9) Why did the address of age and value change?                       Because it calculated and result saved in different location.
+* 10) Step over the cout and cin statements.                            Done               
+* 11) Verify the value entered is stored properly in age.               Yes. it is.
+* 12) Step into until the flow returns to main.                         Done
+* 13) Step over one more time.                                          Done
+* 14) Why didn't the value entered get transferred back to main?        It should be age = GetAge(); but age was omitted.
+* 15) Stop debugging and fix the error.                                 Done
+* 16) Run to Breakpoint 1.                                              Done
+* 17) Step over the function call to GetAge.                            Done
+* 18) Verify that the value entered was returned and stored             Yes, it did.
+*     correctly from GetAge.
+* 19) Stop debugging.
+*
+* Debugging Exercise 2
+*
+* 1) Run to Breakpoint 1.                   Done
+* 2) Step over the call to GetAge.          Done
+* 3) Step into CalcDays.                    Done
+* 4) Step into one more time so that the current line is the
+*    calculation.                           Done
+* 5) Why is age greyed out in your watch window? Because its value is deleted.
+* 6) Stop debugging.
+*
+* Debugging Exercise 3
+*
+* 1) Run to Breakpoint 2.                                               Done
+* 2) When asked, enter the value of 20 for your age.                    Done
+* 3) Verify that the variable age is 20 and the variable days           Yes. it is
+*    is 7300.
+* 4) Step into the PrintResults function.                               Done
+* 5) Age is 7300? Not even Ralph is that old.                           Because the two parameters places were switched.
+* 6) Why did the values for both variables change?                      
+* 7) Stop debugging and fix the error.
+*
+* Debugging Exercise 4
+*
+* 1) Run to Breakpoint 2.                                               Done
+* 2) Display your Call Stack window.                                    Done
+* 3) View the contents of the window and notice that the top            Done
+*    function on the stack is main.
+* 4) Step into the PrintResults function.                               Done
+* 5) Notice that the call stack now shows PrintResults on top of        Done
+*    the stack.
