2. Run-Time Bugs The following program is an upgrade to the Week 3 snowball fight code. Weve changed the movement algorithm and made the code easier to modify by using two functions. Weve also changed what it reports. It has four lines of code that need to be changed but only two real bugs. Youll understand when you find the bugs. The assignment is to find and fix the two bugs. One bug is subtle but does exhibit improper behavior; you just need to be looking closely. Heres a big hint. When a target is hit, it should no longer move or report hits or misses. The other bug is insidious. This is the kind of bug that gets shipped when you dont thoroughly test your code. It has no outward signs of failure but affects the game significantly. Were going to provide some guidance for this bug to help improve your code testing skills. Build the code and then follow these steps. Set a breakpoint at line158, switch (ranNum). The quickest way is to left click to the left of the line number. If a red dot doesnt appear, move the mouse a little farther left. Now start debugging (either hit F5 or use the DEBUG -> Start Debugging menu). Enter in the hit column and row data. You will get one or more target hit or miss reports, and then the program will stop at the breakpoint. (It is possible that the random number will be 4 and the breakpoint wont be triggered for any of the targets in this turn. If that happens, just keep entering column and row data until the breakpoint is triggered.) Youll see a yellow arrow in the red dot. The yellow arrow tells you where the program has stopped. Now look in the Locals window below your source code. (Note: The Locals window is configurable and can be placed anywhere or hidden. The default location is below the source code.) If the Locals window is hidden, try the Alt+4 key combination. The Locals window can also be accessed through the DEBUG->Windows->Locals menu. Left click the + to the left of Target. This should expand the target so you can see all the values, although you can also see the values in the Value column without clicking on the +. Note the value of Target.position (.x and .y). Hit F10. This will cause the program to advance one line of code (single step). The yellow arrow will move and will be pointing at the next line of code to be executed. This should be the first line of one of the case statements. Hit F10 again. If youre lucky, you will be on a line of code that looks like Target.position. . .;. If not, hit F5, which will take you back to Step 3. Cycle through Steps 3, 4, and 5 until you are on a line of code like that shown above. Hit F10 again and note the values of Target.positon. The text in the value line after Target should have turned red, and either the .x or .y value should have changed. Hit F10 three more times and you should be back in the main code at the if (!T.hit) moveTarget(T); line of code. Look at the Locals window. Notice the variables being shown have changed. The local variables in the function are no longer available (they are out of scope), and we are looking at the local variables in Main. Look at the T.position values. Are they the same as the Target.position values? If not, then we havent really moved the Target. Can you figure out why? Remember our discussion of pass by value and pass by reference, especially for structs and std::arrays. You might want to do a little research on the other windows, such as the Autos window and especially the Watch window, which can be very useful.
