思路很清晰的c++课件。例子很简明

例3.3 对象的引用

#include <iostream.h>

class point{
private:
	int x,y;
public:
	void setpoint(int a,int b){x=a;y=b;}
	int getx(){return x;}
	int gety(){return y;}
};

void main()
{	point op1,op2;
	int i,j;
	op1.setpoint(1,2);
	op2.setpoint(3,4);
	i=op1.getx();
	j=op1.gety();
	cout<<"op1中的i="<<i<<",j="<<j<<endl;
	i=op2.getx();
	j=op2.gety();
	cout<<"op2中的i="<<i<<",j="<<j<<endl;
}
