关于类的问题

[看似疯癫]

请帮改下！
#include "iostream.h"
class Line
{
public:
void get( float a1,float b1,float a2,float b2)
{
x1=a1,y1=b1,x2=a2,y2=b2;
}
void k()
{

if((x2-x1)!=0)
{
k1=(y2-y1)/(x2-x1);
cout<<"两直线的k值为："<<k1<<endl;
}
}


void d()
{
cout<<"直线上的两点坐标是：（"<<x1<<","<<y1<<")和（"<<x2<<","<<y2")"<<endl;

}
private:
float x1,x2,y1,y2,k1;
};
void main()
{
// cout<<"请输入直线上两点，并以空格隔开："<<endl;
//cin>>x1>>y1>>x2>>y2;
// float x1,x2,y1,y2;
Line l;
l.get(1.2, 3.1, 3.5, 2.4);
l.k();
l.d();
}

你的错误都是一些基本的语法错误，你自己好好看看，不懂的地方看看书吧。多看书，打好基础啊
