成员函数与构造函数的区别解决方案

成员函数与构造函数的区别
[size=18px][/size]class point
{public:
void intp1(float xx,float yy){X=xx;Y=yy;};
void intp2(float xx,float yy){M=xx;N=yy;};
void move1(float xoff,float yoff){X+=xoff;Y+=yoff;}
  void move2(float xoff,float yoff){X+=xoff;Y+=yoff;}
private:
float X,Y,M,N;
};
class line1:public point
{public:
void intp(float x,float y){intp(x,y);} //成员函数定义
}
class line2:public point
{public:
  line2(float x,float y){intp2(x,y);} //构造函数定义
}
void main
{line1 A;
A.intp(10,20);
A.move1(3,2);

line2 B(10,20);
B.move2(3,2);
}
//为什么 返回的X,M的值不一样，Y，N的值不一样啊

[解决办法]

C/C++ code

Rectangle(float x,float y){    Point(x,y);//注意此处只是定义一个局部的Point对象 并没有修改this->X和this->Y};//应该改为Rectangle(float x,float y) : Point(x,y){};//或者Rectangle(float x,float y){    this->Point::Point(x,y);}
