overload virtual function with different parameters in c++
c++
Solution
The answer is - because that's the way C++ works. The parameters must be the same. C++11 standard says in 10.3.2:
If a virtual member function vf is declared in a class Base and in a class Derived, derived directly or indirectly from Base, a member function vf with the same name, parameter-type-list (8.3.5), cv-qualification, and refqualifier (or absence of same) as Base::vf is declared, then Derived::vf is also virtual (whether or not it is so declared) and it overrides 11 1 Base::vf.
Problem
I want to overload virtual function with different parameters in c++ but it doesn't work. ``` virtual void Draw( int nDeltaX, int nDeltaY); virtual void Draw( int nDeltaX, int nDeltaY, bool m_bFlag); ``` Can you tell me the reason?
