Question:
Fix the following 3 errors.
This program does not work. There are three errors that you will need to fix:
TODO: Fix the following 3 errors.
ERROR #1) The compiler knows there is something wrong, and it will issue a warning and and two error messages, all related to the same problem. Read the error and warning messages carefully to point you in the right direction. Did you know if you double-click on an error message (in the Error List) that it will take you to the spot in your program where the compiler detects the problem? Also, get in the habit of ALWAYS reading messages carefully. You may not understand them right now, but over time you will come to understand the messages better and better. One of these three messages will be most helpful, but it is still informative to see that the other two messages come as a result of this single problem.
ERROR #2) After fixing ERROR #1 your program will run. However, you will get incorrect results. It will say "Congratulations!" even when not perfect.
ERROR #3) But when you find and fix that error, something still lurks behind that the compiler does not complain about and that will give incorrect output. The output will still display a zero after the decimal point even if it should be .3 or .7...
IMPORTANT NOTE ON ERROR #3: You are NOT allowed to change the data type of any constant or variable to make this work. You also MUST divide by NUM_OF_SCORES when calculating the average.
