C++編程問題，求大神

class RMB

{

private:

int yuan,jiao,fen;

double general;

public:

RMB(double x){general=x;yuan=(int)x;jiao=(int(x*10))%10;fen=(int(x*100))%10;}

RMB(int x,int y,int z){yuan=x;jiao=y;fen=z;general=x+y/10.0+z/100.0;}

RMB(RMB& x){yuan=x.yuan;jiao=x.jiao;fen=x.fen;general=x.general;}

void getGeneral(){general=yuan+jiao/10.0+fen/100.0;}

void getSingle(){yuan=(int)general;jiao=(int(general*10))%10;fen=(int(general*100))%10;}

void disPlay(){printf("yuan=%d jiao=%d fen=%d general=%.2f\n",yuan,jiao,fen,general);}

};

void main()

{

RMB A(1,2,3);

A.disPlay();

RMB B(5.67);

B.disPlay();

RMB C(B);

C.disPlay();

}

有不明白的可以問我，滿意的話請采納
