Programming Exercise 15, Chapter 11, describes how to design the class pointType to implement a point. Redo this programming exercise so that the class pointType:
a. Overloads the stream insertion operator, <, for=”” easy=”” output.=””>
b. Overloads the stream extraction operator, >>, for easy input. (A point is input as (a, b).)
c. Overloads the assignment operator to copy a point into another point.
d. Overloads the binary operator +, as a member function, so that it returns the distance between two points.
e. Overloads the operator ==, as a member function, so that it returns true if two points are the same; false otherwise.
f. Overloads the operator !=, as a member function, so that it returns true if two points are not the same; false otherwise.
g. Write a program to test your class.
