C++源码：实现传址参数的实例

//  C++源码：实现传址参数的实例 Example for & parametor

  cout<<"\n\n   You are wellcome to Tsinghua!   Example for & parametor    传址 参数 \n\n";
 
  cout<<"\007"<<"\n\n    Please input the vallue of X and Y:"<<flush;    // fflush功能:清除读写缓冲区
  cin>>x>>y;
  cout<<"\nX="<<x<<"\nY="<<y;
  swap (x,y);
  cout<<"\n\n Now,after SWAP(int&a,int&b), X="<<x<<",Y="<<y << "\n\n";
