/********************************************************************
* 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. 0x000000ee717cf554{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? It changed because we went through age in the from GetAge function and set us up for some new address in the new function.
* 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? It looks we need to pass by reference into fain. When we went into calcdays we felt that we haven't gotten the right age into that function yet. We were in a different function and we ran through the main function to change the work in the name value of the age.
* 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? It is stale do to a problem that came with evaluating it.
* 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? We needed to fix the work of what is the Calcdays function and add that into the main function.
* 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.
