Write a program which overloads a binary Minus (+) operator,
The program will contain a class Matrix, This class will contain a
private data member Array[][] which store int values. The class will
further contain a Default constructor, get() function which takes
values for array from the user and also contain a Display function
witch display the array on the screen,
In main function create three objects Mat1, Mat2, Mat3 of this class,
first call get() and Display() functions with Mat1 and Mat2 objects
then implement the statement Mat3 = Mat1 + Mat2; and call Display()
function with Mat3.
It wasn't immediately evident to me if you had followed any of the advise
you were given. I will give you the benefit of the doubt and assume you
changed *something*. Your compiler is old and the code had to be modified to
meet current standards. It also used (unnecessarily) one non standard
header. The following compiles but you will have to find what I changed and
undo to make it work on your compiler. I changed perhaps 20-30 things.
Then, when you are have recovered, start adding stuff back in. SLOWLY!!!
You don't seem to be big on following advise but I will give you some
anyhow. The DevC compiler is easily installed and has a nice GUI and you
can recover your current state fairly easily. I suggest you download it and
use it from now on.

If you use tabs instead of spaces they get lost between you and my display.
The resulting code is the following plug ugly format. I suspect "plug ugly"
is an American idiom. It means "really, really ugly".
