CSCI - Assembler Language
Assignment 4.

In this assignment you convert your multiply routine to a
subroutine. If this subroutine were written in C++, it would be
prototyped as: int product(int a, int b);  That is to say it takes
two ints as arguments and returns their product.  You then test it
as follows.

Prog 4.1  Input two numbers (in main) and use product to compute the
product of the two numbers. Output the result with a suitable message.

Prog 4.2  Input a number, say n, from the user.	 Then call the fact
subroutine to compute the factorial of n.  The fact subroutine will
need to call your product subroutine.
