I have been given an assignment to design and program a calculator using C++ and Ultimate ++IDE(Integrated development Environment). My code should have a class Calculator as a base class, and another class scientificCalculator which inherits from class Calculator. The Calculator class performs basic arithmetic operations. The scientificCalculator adds more operations, and is able to compute Sine, Cosine, Tangent, Logarithm and Exponential computations. Please can someone come to my rescue because I have to submit by the 22nd November 2009.
