Question

The coordinates of a point P on a two dimensional plane can be represented by P(x,y) with x as the x-coordinate and y as the y-coordinate.The coordinates of midpoint of two points P1(x1,yI) and P2(x2,y2) can be calculated as P(x,y) where:

x=(xl+x2)/2,y=(y1+y2)/2

Design a class Point with the following details:

Classname : Point

DataMembers / instancevariables:

x: stores the x-coordinate
y : stores the y-coordinate

Member functions:
Point():constructor to initialize x=0,y=0
void readpoint():accepts the coordinates x and y of a point
Point midpoint(PointA,PointB):calculates and returns the midpoint of the two
points A and B
void displaypoint():displays the coordinates of a point

Specify the class Point giving details of the constructor() , member functions void readpoint() ,Point midpoint(Point,Point) and void displaypoint() along with the main() function to create an object and call the functions accordingly to calculate the midpoint between any two given points.
