如何通过指向派生类的基类指针调用基类方法

How to call Base class method through base class pointer pointing to derived class(如何通过指向派生类的基类指针调用基类方法)

问题描述

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? */
}

推荐答案

pBase->Base::foo()
