Override and overload in C++

Question

Yes, I do understand the difference between them. What I want to know is: why OVERRIDE a method? What is the good in doing it? In case of overload: the only advantage is you

Answer 1

Override is useful when you inherit from a base class and wish to extend or modify its functionality. Even when the object is cast as the base class, it calls your overridden function, not the base one.

Overloading is not necessary, but it sure makes life easier or more readable sometimes. Arguably it can make it worse, but that's when it should not be used. For example, you can have two functions that perform the same operation, but act on different kinds of things. For example Divide(float, float) should be different from Divide(int, int), but they're basically the same operation. Wouldn't you rather remember one method name, "Divide", than have to remember "DivideFloat", "DivideInt", "DivideIntByFloat", and so on?
