 * 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

+* 8) Step into one more time.                                           Done

+* 9) Why did the address of age and value change?                       Because it calculated and result saved in different location.

+* 14) Why didn't the value entered get transferred back to main?        It should be age = GetAge(); but age was omitted.

 * Debugging Exercise 2

 *

-* 1) Run to Breakpoint 1.

-* 2) Step over the call to GetAge.

-* 3) Step into CalcDays.

+* 2) Step over the call to GetAge.          Done

+* 3) Step into CalcDays.                    Done

 * 4) Step into one more time so that the current line is the

-*    calculation.

-* 5) Why is age greyed out in your watch window?

+*    calculation.                           Done

+* 5) Why is age greyed out in your watch window? Because its value is deleted.

 * 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

-* 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?

+* 4) Step into the PrintResults function.                               Done

+* 5) Age is 7300? Not even Ralph is that old.                           Because the two parameters places were switched.
