Question

Is the following code the correct way to call a base class’s overridden function from a derived class’s function?:

#include "stdafx.h"
#include <iostream>

class BaseClass
{
public:
    virtual void foo()
    {
        std::cout << "BaseClass::foo()" << std::endl;
    }
};
class DerivedClass : BaseClass
{
public:
    virtual void foo()
    {
        __super::foo();

        std::cout << "DerivedClass::foo()" << std::endl;
    }
};
int main()
{
    DerivedClass* dc = new DerivedClass();

    dc->foo();

    delete dc;

    return 0;
}

Answer 1

No, your call using __super::foo() is employing a Microsoft language extension.

Instead you can write BaseClass::foo().

Or if you have a typedef BaseClass Base, then Base::foo().
