/********************************************************************
* File: Chap_5_Debugging.cpp
*
* General Instructions: Complete each step before proceeding to the
* next.
*
* Debugging Exercise 1
*
* 1) On the lines indicated in the code below, insert a breakpoint.
* done
* 2) With the program not in debugging mode, start debugging by
* using the "Step Into" tool.
* done
* 3) Click on the Watch1 tab.
* done
* 4) With the cursor in the Name column type money and press enter.
* This adds a programmer defined watch on the variable money.
* done
* 5) Step Into until you reach the first cout statement. With
* the current line being that cout statement, Step Into again.
* done
* 6) What happened? Where are we now? What is all of this nasty
* looking code?
* We are on line 84. the value of 'money' is about to be printed (123.449997 is the assigned value, though it will print 123.45).
* That said, I don't see any assembly code displayed.
*
* 7) Remember, stepping into a predefined routine takes you to the
* code for that routine. If the debugger can't find the code it
* will show the assembly code for that routine.
* done, though I did not see the assembly code pop up anywhere.
*
* 8) How do we get out of this mess? Use the "Step Out" tool.
* done, though upon selecting the step out tool (Shift + F11) the code appears to finish running at this point.
* 9) In Visual Studio you will be taken back to the same cout
* statement. Use the Step Over tool to take you to the next
* line.
* done
* 10) Step over the next cout statement. Now look at the console
* window. What was printed?
* The following was printed:
*
* You have $123.45
* Enter percent raise:
*
* This isn't exactly what I expected though.. The Step Out tool doesn't seem to be stepping back and instead goes to the next cout.
*
* 11) Select Stop Debugging either from the Debug menu or from your
* toolbar.
*done
*/
/*
* Debugging Exercise 2
*
* 1) With the program stopped, run to Breakpoint 1 by selecting
* the Start Debugging menu option, toolbar icon or press F5.
* done
*
* 2) Step over the cout.
* done
*
* 3) Step over the cin. Notice that you can now enter a value.
* done
*
* 4) Enter the value .1 and press enter.
* done
*
* 5) Notice that the current line of execution is now at the
* calculation.
* done
*
* 6) Look at your watch. What is the value of money?
* 123.449997
*
* 7) Hover your mouse pointer over raise. What is its value?
* .100000001
*
* 8) Step over the calculation. Notice the watch on money is now
* red. This designates that the variable just changed its value.
*
* 9) What happened to our money? I thought a raise was supposed
* to increase our money? Stop debugging and fix the calculation.
* It asks for a % raise, though we entered .1
* It then multiplies by that number which shows us one tenth of the value of our money, rather than applying a 10% raise.
*
*/
/* Debugging Exercise 3
*
* 1) Choose Disable All Breakpoints from the Debug menu.
* done
*
* 2) With the cursor on the calculation, Run to Cursor. Remember
* that the Run to Cursor tool can be accessed by right clicking
* in the code window and choosing the correct menu option.
* done
*
* 3) Step over the calculation and verify that this time
* you end up with more money than before the raise.
* done; verified... $129.622
*
* 4) Stop debugging. Now run the entire program by choosing the menu
* option Start Without Debugging.
* done
*
