#include <iostream.h> 

class Move 

{

private:

  double  x;

  double  y;

public:

  Move(double a=0, double b=0);      

  showmove() const;                

  Move add(const Move & m)  const; 

   rest (double a=0,double b=0);  

};  

Move::Move(double a, double b)

{

 x=a;

 y=b;

}

Move::showmove() const 

{

cout << x << "," << y <<endl;

}

Move Move::add(const Move & m) // const

{

    return Move(x+=m.x,y+=m.y);

}

Move:: rest (double a,double b)

{

x=a;

y=b; 

} 

int main()

{

Move m(2,5);

m.showmove();

Move aa(1,3);

aa.showmove();

Move mm;

mm=aa.add(m);

mm.showmove();

mm.reset(1,12);

mm.showmove();

mm.reset();

mm.showmove();

system("pause");

return 0;

}

程序有多个错,改好的
