-* General Instructions: Complete each step before proceeding to the

-*
-* 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?
-* 8) Fix this problem by removing the ; after the while statement.
-* 9) Stop debugging and repeat Steps 2 � 5 to verify the correction
-* worked.
-* 10) Stop debugging.
-*
-* Debugging Exercise 2
-*
-* 1) Run to Breakpoint 1.
-* 2) Step into the while loop.
-* 3) Why did the cout not execute?
-* 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.
-* 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.
-*
-* 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?
-* 6) Where was 10 assigned to count?
-* 7) Fix the problem and re-run to verify.

+*

+* 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?
+i is esatblished as zero and the while loop is checking for while i <0, which 0 is not less than zero so it doesn't loop back. Also there's a semicolon
+after the while loop so it terminates the while loop anyways.
+* 8) Fix this problem by removing the ; after the while statement.
+* 9) Stop debugging and repeat Steps 2 � 5 to verify the correction
+* worked.
+* 10) Stop debugging.
+*
+* Debugging Exercise 2
+*
+* 1) Run to Breakpoint 1.
+* 2) Step into the while loop.
+* 3) Why did the cout not execute?
+* Because the while statement is when i<0, but i = 0, so the while loops gets skipped over.
+* 4) Check the value of i, now check the condition, does the
+* condition evaluate to true?
+* No, i is not less than 0 because i equals zero.
+* 5) Change the "< 0" to a "< 10".
+* 6) Stop debugging and repeat Steps 1 � 4 to verify the correction
+* worked.
+* The cout is not being skipped over anymore.
+* 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.
+* The output is 0-9 in the while loop.
+*
+* 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.
+* 640, checks out.
+* 4) Step into the loop.
+* 5) What is the value stored in count now?
+* 10
+* 6) Where was 10 assigned to count?
+* The loop, since the for loop has a semicolon on the front, it still goes through the process, but doesn't preceed to the next line.
+* So the loop sets count to 0 and adds one until count =10. By removing the semicolon, it now counts properly from 0-9, like the while loop.
+* 7) Fix the problem and re-run to verify.
