《C&C++完美演绎》源代码

				/* 范例：18-5 */
				#include 
				class Base

				  public:
				    virtual void fun1(){ cout 				    void fun2(){ cout 				};
				class Derived:public Base

				  public:

				  Derived  *obj_Derived = new Derived ;
				  Base     *obj_Base    = new Derived ;
				  obj_Base->fun1();  	/* 调用Derived::fun1()，依照链接 */
				  obj_Base->fun2();  	/* 调用Base::fun2()   */
				  obj_Derived->fun1(); 	/* 调用Derived::fun1()，依照链接 */
				  obj_Derived->fun2(); 	/* 调用Derived::fun2() */
				  delete obj_Base;
				  delete obj_Derived;

				程序执行结果：
				Derived::fun1
				Base::fun2
				Derived::fun1
				Derived::fun2
