/********************************************************************
* File: Chapter 9 Debug.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?	-	Becuase it's moved into a function without using pass by reference.
* 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?	-	Becuase it's not passed the value by reference, or called by "age = GetAge();" the value doesn't pass on.
* 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?	-	Becauase CalcDays doesn't have access to age.
* 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?	-	Becuase the function had it reversed from the call. The function needed to be "(int age, int days)" instead of "(int days, int age)"
* 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.
