Answer to Question #204740 in C++ for hunny

Question

Consider the class of points in the xy plane. The location of each point is determined by the real numbers (x, y) specifying the cartesian coordinates. The class definition is: #include using namespace std; class point{ public: point(); point(double value_x, double value_y); double get_x() const; double get_y() const; void print() const; void move(double dx, double dy); private: double x, y; }; point::point(){ x = 0.0; y = 0.0;} point::point(double a, double b){ x = a; y = b; } void point::print() const{ cout< A = point(1, 2); A.print(); A.move(4, -5); A.print(); pointB(3.2, 4.9); cout << B.get_x() <<""<< B.get_y() << endl ; point C("day", "young"); C.print(); C.move("s","ster"); C.print(); return 0;

#include<iostream>
#include<string>


using namespace std;
template<class type>
class point{
public: 
	point(); 
	point(type value_x, type value_y); 
	type get_x() const; 
	type get_y() const; 
	void print() const; 
	void move(type dx, type dy); 
private: 
	type x, y; 
};
template<class type>
point<type>::point(){ 
	x = NULL; 
	y = NULL;
} 
template<class type>
point<type>::point(type a, type b){
	x = a; 
	y = b;
}
template<class type>
void point<type>::print() const{
	cout<<x<<" "<<y<< endl;
}
template<class type>
type point<type>::get_x() const{
	return x;
}
template<class type>
type point<type>::get_y() const{
	return y;
}
template<class type>
void point<type>::move(type dx, type dy){
	x = x+dx;
	y = y+dy;
}


int main(){
	point<int> A = point<int>(1, 2);
	A.print();
	A.move(4, -5);
	A.print();
	point<float>B(3.2, 4.9);
	cout << B.get_x() <<" "<< B.get_y() << endl ;
	point<string> C("day", "young");
	C.print();
	C.move("s","ster");
	C.print();


	
	return 0;
