-* 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.
-* 0x00000059fe1df894 {0}
-* 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?
-* The address of age changed to 0x00000059fe1df774 {-858993460} and the value of age changed to -858993460.
-* The reason why the values of age and it's address changed is becuase we re-instantiated the variable but didn't give it variable, so it just became filled with garbage
-* 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?
-* We jump back to main and set age back to 0 because we run the age = 0 segment
-* 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.
