/*******************************************************************************
The mixture testing program including Addition, Subtraction, Multiplication,
Division (integer) and Mudular:  This program will generates two random numbers
REPEATEDLY and invite the user to input the answer.
It will then check the answer and report 'right' or 'wrong'.  The user can choose
to do any of the five types of calculations and decide to continue or finish.
