Can't call base class's method when another overload present in derived class

Question

I get a compiler error \"function does not take 0 arguments\" when compiling the following code.

class A
{
public:
    int Foo()
    {
        return 1;
             


        

Answer 1

Add this line:

using A::Foo;

in class B (public part) and it will work.

In this case Foo from B hides Foo from A. One of the C++ strange behaviors.
