+ * Andrei Florea - CST116 - CH8 - Debugging

+ *

+* File: CST116-Ch8-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 i.

+* 4) Execute the while statement by doing a "Step Into".

+* 5) The execution continues to the cout statement as expected.

+* 6) Step over the cout statement.

+* 7) Why didn't the flow of the program return back to the while

+*    statement?

+ *

+ *    The flow of the program did not return to the while statement because of the semicolon on the while statement,

+ *    this is also explained in the next step. The brackets, which I thought had an error to do with the

+ *    flow of the program not returning to the while statement do not matter here.

+ *

+* 8) Fix this problem by removing the ; after the while statement.

+* 9) Stop debugging and repeat Steps 2 � 5 to verify the correction

+*    worked.

+ *

+ *    Done, however, debugging will now not enter the while block to execute the cout statement.

+ *

+* 10) Stop debugging.

+*

+* Debugging Exercise 2

+*

+* 1) Run to Breakpoint 1.

+* 2) Step into the while loop.

+* 3) Why did the cout not execute?

+ *

+ * The cout did not execute because the while loop is comparing if the variable i is less than 0.

+ * However, the variable i is initialized as 0, and therefore is not less than 0, so it does not step

+ * into the while loop.

+ *

+* 4) Check the value of i, now check the condition, does the

+*    condition evaluate to true?

+* 5) Change the "< 0" to a "< 10".

+* 6) Stop debugging and repeat Steps 1 � 4 to verify the correction

+*    worked.

+ *

+ *    It works but it's an infinite loop.

+ *

+* 7) Stop debugging.

+*

+* Debugging Exercise 3

+*

+* 1) Run the program without debugging.

+* 2) What is happening now is an infinite loop.

+* 3) End your program by holding down the Ctrl key and pressing C.

+* 4) Fix the problem by adding a "++" after the i in the cout

+*    statement.

+* 5) Run the program to Breakpoint 2 and verify that the output

+*    displayed on the screen is 0 � 9.

+ *

+ *    Yes, if I add another breakpoint after the while loop block and run it in debug mode and check the console,

+ *    the outputs are 0 to 9. However, the variable i is equal to 10, which makes sense because that is how it

+ *    got out of the while loop block.

+*

+* Debugging Exercise 4

+*

+* 1) Run to Breakpoint 2.

+* 2) Add a watch to the variable count.

+* 3) Verify that the contents of count is garbage.

+* 4) Step into the loop.

+* 5) What is the value stored in count now?

+ *

+ * The value stored in count before was 1, but after stepping into the loop the value stored is now 10

+ *

+* 6) Where was 10 assigned to count?

+ *

+ * I believe the 10 was assigned to count on line 99, where basically it just did a loop on that line without entering

+ * the line below, and it did it until count was equal to 10.

+ *

+* 7) Fix the problem and re-run to verify.

+ *

+ * I fixed the problem, which was the same as the other loop with the semicolon on the for loop.

+ * I know the problem is fixed as I used the debugging tool and followed the flow of the code, entering

+ * the for loop until count was 10

+ *

+ * I am also adding curly brackets (which are not necessary as I found out) but it makes the code cleaner

+ * and easier to read.
