(c) Write a following C++ program to explain objects as function
arguments. Define a class name ?Point? with two data member
variable x and y, member function for getting the value of member
variable from user and second member function for displaying the
value of member variable. Define third member function that takes
another Point object as an argument and returns the Euclidean
distance between the two Point objects. [for point P(x1,y 1) and point
