c++封装之对象成员基础

基础对象成员

//坐标类class Coordinate{public:Coordinate();~Coordinate();void setX(int _x);int getX()；void setY(int _y);int getY();public:int x,int y;};
//线段类class Line{public:Line();~Line();void setA(int x,int y);void setB(int x,int y);void print();private:Coordinate A;Coordinate B;
};

void Line::setA(int x,int y){ A.setX(x); A.setY(y);}//同理B点
