Overload of pure virtual function

Question

I usually use pure virtual functions for those methods that are required by my code to work well. Therefore, I create interfaces and then other users implement their derived

Answer 1

It is not overriding as the function signatures are different. According to polymorphism rule to override a function the function signatures and types should be same.

In this case these functions are different. virtual void foo(int,double)=0; virtual void foo(int, double, double);
