class shape{

public:
  void Print() { cout <<"I'm shape .\n";}
  void draw(){cout <<"I'm drawing .\n";}
  void move(){cout <<"I'm moving .\n";}
  void hide(){cout <<"I'm hiding .\n";}
  void show(){cout <<"I'm showing .\n";}
};




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?

貌似直接draw()就行

另外试一试shape::draw()

主函数像这样
void main()
{
  Diamond s;
  s.Print();
.......

试一试s.draw();

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

后面加一个分号

#include "stdio.h"
#include "iostream.h"

class shape
{
public:
void Print(){ cout <<"I'm shape .\n";}
void draw(){cout <<"I'm drawing .\n";}
void move(){cout <<"I'm moving .\n";}
void hide(){cout <<"I'm hiding .\n";}
void show(){cout <<"I'm showing .\n";}
};

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"; }
};

int main()
{
Diamond d;
d.draw();
return 0;
}

通过

7楼继承好像真的不行
