a) Which line in the class definition contains the constructor?

b) Give the prototype and defintion for the overloaded + operator, that will add two points. You can define the addition of two points as follows: (x1,y1) + (x2,y2) = (x1+y1,x2+y2)

prototype:_____________________________________________

definition:

c) Assume the class defintion above, plus the added overloaded addition from question b). What is printed by the following code?

int main()

{

// Some points.

Point a(5.2, -4.8);

Point b(1.0, 9.0);

Point d; //look at default values

a.print();

b.print();

d.print();

cout

b.move(2,-5);

b.print();

(a + b).print();

cout

b.print();

cout

d.print();

cout

}

d ) Suppose that we want users to input a point in the following format (note that the numbers here are just examples; the user can input any doubles): (2,3.5) Give the prototype and definition for the overloaded >> operator.

prototype:____________________________________________________________

definition:

2) Here is a class definition for a Point class. Objects in the class represent points on the Cartesian Graph. 1 class Point 2 public Uses default arguments to allow calling with zero, one or two values. Point (double x 0.0, double y 0.0) Computes distance to another point using Pythagorean theorem. double dist (Point other) Move the existing point. void move (double a double b) //print the point nicely 10 void print 11 12 private: 13 double xval double val; 15 Point:: Point (double x, double y) xval yval void Point move (double a double b) xval val b; double Point dist (Point other) double xd J xval other. xval; double ya yval other yval return sart (xd*xd yd yd); void Point print cout
