vc++的实验和实训例子非常适合初学者学习和阅读

#include<iostream.h>
class Sample
{
  int n;
public:
	Sample(int i){n=i;}
	operator++(){n++;}//前缀重载运算符
	operator++(int){n+=2;}//后缀重载运算符
    void disp()
	{
	  cout<<"n="<<n<<endl;
	}
};
void main()
{
  Sample A(2),B(2);
  A++;//调用后缀重载运算符
  ++B;//调用前缀重载运算符
  A.disp();
  B.disp();
}
