+* 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.
+* 2) Run to Breakpoint 1.
+* 3) Place a watch on age and days.
+* 4) Add another watch using &age for the name. This will display
+* the address of age.
+* 5) Write down the address of age.
+* 6) Step Into the code for the function GetAge.
+* 7) The execution continues to the function header for GetAge.
+* 8) Step into one more time.
+* 9) Why did the address of age and value change?
+* 10) Step over the cout and cin statements.
+* 11) Verify the value entered is stored properly in age.
+* 12) Step into until the flow returns to main.
+* 13) Step over one more time.
+* 14) Why didn't the value entered get transferred back to main?
+* 15) Stop debugging and fix the error.
+* 16) Run to Breakpoint 1.
+* 17) Step over the function call to GetAge.
+* 18) Verify that the value entered was returned and stored
+* correctly from GetAge.
+* 19) Stop debugging.
+*
+* Debugging Exercise 2
+*
+* 1) Run to Breakpoint 1.
+* 2) Step over the call to GetAge.
+* 3) Step into CalcDays.
+* 4) Step into one more time so that the current line is the
+* calculation.
+* 5) Why is age greyed out in your watch window?
+* 6) Stop debugging.
+*
+* Debugging Exercise 3
+*
+* 1) Run to Breakpoint 2.
+* 2) When asked, enter the value of 20 for your age.
+* 3) Verify that the variable age is 20 and the variable days
+* is 7300.
+* 4) Step into the PrintResults function.
+* 5) Age is 7300? Not even Ralph is that old.
+* 6) Why did the values for both variables change?
+* 7) Stop debugging and fix the error.
+*
+* Debugging Exercise 4
+*
+* 1) Run to Breakpoint 2.
+* 2) Display your Call Stack window.
+* 3) View the contents of the window and notice that the top
+* function on the stack is main.
+* 4) Step into the PrintResults function.
+* 5) Notice that the call stack now shows PrintResults on top of
+* the stack.
