How to call Base class method through base class pointer pointing to derived class

Question

class Base
{
  public:
    virtual void foo()
    {}
};

class Derived: public Base
{
  public:
    virtual void foo()
    {}
};

int main()
{
    Base *pBase = NULL;
    Base objBase;
    Derived objDerived;

    pBase = &objDerived;
    pBase->foo();

    /*Here Derived class foo will be called, but i want this to call 
    a base class foo. Is there any way for this to happen? i.e. through 
    casting or something?*/
}

Answer 1

pBase->Base::foo()

Answer 2

You can do it through scope resolution operator ::

Something like this:

pBase->Base::foo()

Answer 3

Both responses above are correct...But be careful, if you need to do that, maybe you have a big problem about the conception or the design...
