Do the following with class Shape: a. Add prototypes for all required methods and operators for
the class (the Point class is the one from problem one above).

template <class T>
class Point

TÂ Â X;
TÂ Â Y;

Point() {
X=0;
Y=0;

T getX() {
return X;

void setX(T x) {
X = x;
}
T getY() {
return Y;

void setY(T y) {
Y = y;

Point operator+(Point a, Point b) {
Point r;
r.X = a.X+b.X;
r.Y = a.Y+b.Y;
return r;
}
};

Solution
Along with solution i am also correcting the operator + function.
The operator + is within the class so it will accept one argument only. Two argument is required
in case of friend functions.
#include <iostream>
using namespace std;
template <class T>
class Point
{

private:
T X;
T Y;
public:
Point() {
X=0;
Y=0;
}
T getX() {
return X;
}
void setX(T x) {
X = x;
}
T getY() {
return Y;
}
void setY(T y) {
Y = y;
}
Point operator + (Point<T> a) {
Point<T> r;
r.X = a.X+this.X;
r.Y = a.Y+this.Y;
return r;
}
};
template <class T>
class Shape
{
public:
T area_rectangle(T ,T ); // prototype to calculate area of rectangle
T area_circle(T ); // prototype to calculate area of circle
Point<T> operator * (Point<T> );// prototype for multiplication used in area of rectangle
Point<T> operator / (Point<T> );// prototype for division used in area of circle(22/7 as pie)
private:
Point<T> Origin;
};
