Question

I need to write a class in C++ that would represent an abstraction of a calculation. That class will have a function that will run an actual calculation.

class Calculation {
    Calculation() {}
    ~Calculation() {}

    Calculate(); //member function that runs a calculation
};

I need that class to be able to represent different sorts of calculations and run different calculation as the result of calling Calculation::Calculate(). What are some good approaches to do this in C++? I could do that just passing some flags into constructor, but this doesn’t seem to be a good solution.

Answer 1

You can make Calculate virtual and create child classes that implement the varying behavior you need.
