The purpose of this exercise is to become familiar with the use of typedef, global contants, classes, and header files.
Now everywhere you had specified the limit "3" in the class file
and the main file, replace that value with Nmarks.
Just for interest, keep track of the number of changes you have
If you were NOT using the const, this is number of
changes you would have to make every time you wanted to change
the array size.
After you've recompiled and run, go back to the .h file and change the limit to 2. With the const, you only have to make this one change to change the array size.
Don't change anything else; just recompile and run to make sure the project is now generic for the number of marks.
