【求助】c++运算符重载

Point.h:
namespace main_savitch_2A
{
  class point
  {
    public:
      point(double x_amount,double y_amount)
      {
           x = x_amount;
           y= y_amount;
       }
      double get_x() const {reurn x;}
      double get_y() const { return y;}
      ostream& orerator << (ostream& outs,const point source);
    private:
       double x;
       double y;
}
..................
Point.cpp:
#include"Point.h"
namespace main_savitch_2A
{
      ostream& point ::operator << (ostream &out, const main_savitch_2A::point &source)
    {
        outs << source.get_x() << "" << source.get_y() << endl;
        return outs;
    }
}


编译的时候，总是说重载操作符那里的变量太多，那位达人知道是怎么回事啊，能否给个版本，简单写下就好
