I've been trying to write a class called Point, with a file Point.cpp including a header file Point.h . I tried to set a global variable of type Point called ORIGIN, however I get an error message saying "error: ‘ORIGIN’ does not name a type"

Point.h is as follows:

```
// Point.h
//#include <iostream>
#include <string>
#include <cmath>
#include <cstdlib>
#ifndef POINT_H
#define POINT_H
using namespace std;
class Point{
public:
//Point(double a, double b);
Point();
void setPoint(Point &p, double a, double b);
friend istream& operator>>(istream& cin, Point& p);
friend ostream& operator<<(ostream& cout, const Point& p);
friend double operator - (const Point& p1, const Point& p2);
double x,y;
//private:
//double x,y;
};
extern Point ORIGIN;
istream& operator>>(istream& cin, Point& p);
ostream& operator<<(ostream& cout, const Point& p);
double operator - (const Point& p1, const Point& p2);
#endif
```

Point.cpp is as follows:

```
// Point.cpp
#include "Point.h"
Point ORIGIN;
//ORIGIN = setPoint(ORIGIN,0,0);
ORIGIN.x = 0;
ORIGIN.y = 0;
void Point::setPoint(Point& p, double a, double b){
p.x = a;
p.y = b;
}
Point::Point(){
//setPoint(this,0,0);
}
istream& operator>>(istream& cin, Point& p){
string str, str_x, str_y;
int comma;
cin >> str;
comma = str.find(",");
str_x = str.substr(1,comma-1);
str_y = str.substr(comma,str.length()-3-str_x.length()); // -3 is from "(" "," and ")"
p.x = atof(str_x.c_str());
p.y = atof(str_y.c_str());
}
ostream& operator<<(ostream& cout, const Point& p){
cout << "(" << p.x << "," << p.y << ")";
}
double operator - (const Point& p1, const Point& p2){
double distance;
distance = sqrt( pow( (p2.x-p1.x),2) + pow( (p2.x-p1.x),2));
return distance;
}
```

I have a feeling the error has something to do with the part in Point.cpp where I try to assign values to ORIGIN's x and y member variables, although I'm not quite sure how to fix this :(

any help would be appreciated, thanks!
