class Quadrangle : public shape
{
public:
  void Print() { cout << "I'm Quadrangle\n"; }
}


class Diamond : public Quadrangle
{
public:
  void Print() { cout << "I'm Diamond.Diamond is Quadrangle\n"; }

};

diamond怎么调用爷爷的DRAW等方法?

明白楼住的意思了
#include "stdio.h"
#include "iostream.h"

class shape

class Quadrangle : public shape

class Diamond : public Quadrangle

调用Diamond的爷爷的方法 就是说掉用 shape::print()方法!
这个 调用就是啥子意义都没有啊!!!!!!
不知道要调用shape::print()有什么意义!!!!!

估计楼住原来是说怎么调用 Diamond:print()方法吧?

使用virtual 就可以了哈
