Click on the '+' in the +* watch window to see the individual elements associated with each +* of the arrays. +* 6) Continue running your program to Breakpoint 2. +* 7) Add a watch on the array called name. Again, click on the '+' +* symbol. Notice how a multidimensional array is shown in the +* debugger, the null terminating characters location, and how a +* character is represented within each element of the array. +* 8) Continue running the program to Breakpoint 3. +* 9) Notice the contents of varX and varY now that you are back in the +* main function. +* 10) Clear all the breakpoints. +* 11) Stop debugging. +* +* Debugging Exercise 2 +* +* 1) Change the constant SIZE from 5 to 10. +* 2) Change any literal containing a 5 to the constant SIZE. +* Notice the usefulness of the constant when changes need +* to be made to your code. +* 3) Set a breakpoint at Breakpoint 4. Now on this breakpoint +* set the necessary condition so the loop breaks when x hits 8. +* (Hint: If you need help setting breakpoints based upon a +* condition refer to Chapter 8). +* 4) Run to Breakpoint 4. +* 5) Continue stepping into the remainder of the for loop until the +* flow returns back to main. +* 6) Make sure your Watch window is visible and notice the contents +* of varY and varZ now that you are back in main. +* 7) Stop debugging. +* 8) Disable all breakpoints. +* 9) Rebuild and execute the program and verify the results. +* +* Debugging Exercise 3 +* +* 1) Just before the call to the PrintFunction in main, add an +* assignment statement to change the first element in the +* array varZ to -99. +* 2) Build and execute your code, verifying that the calculations +* are correct in relation to element 0 of varZ. +* 3) Add a line to assign the contents of the second element of +* varX to 99 in FunctionTwo. +* 4) Rebuild your program. +* 5 Obviously there is a problem. Remove the const from the +* function declaration and header for varX. +* 5) Now you should be able to build and execute your code. Do it. +* 6) Set a breakpoint on Breakpoint 2. +* 7) Re-enable Breakpoint 2. +* 8) Run to Breakpoint 2 and make sure you have a watch on the +* variable name. +* 9) Click on the '+'. Once you see all the elements +* within the array, change the 'Value' (in the Value field) +* for the first element of the array directly within the Watch +* window to the character 'Z'. Notice how the value is updated +* by displaying the new ASCII value too. +* 10) Stop debugging. +* 11) Disable all breakpoints. +*
