COMP 3141: Object Oriented Design and Programming

Project (10%)

Problem:

You need to develop a program code to build a calculator. The program should open with two options of:

a.   Basic calculator

b.   Scientific calculator

Basic calculator—This will allow the six basic functions of:

a.   Addition

b.   Subtraction

c.   Multiplication d.  Division

e.   Square root f.    Square

Scientific calculator—This will allow mathematical operations for sine, cosine, etc. (You may lead to the level of operations.)

The project is done in two phases:

Phase 1

Plan all the classes with constructor, destructor, accessor, and mutators. You will need to do the class declaration in a header(.h) file, and the class implementation in the .cpp file.

Now add more methods in the classes for display and other calculations.

Phase 2:

Design the driver program to display a menu to take user input for the type of calculator the user wishes to use. The calculator should keep on working until the user wishes to quit. Also, there should be a chance given to the user to switch to the alternative mode without closing and re-running the entire program.
