Implement comparison operator overload for comparing the salary of Point object. a) Overload the operator == to output boolean. Implement arithmetic operator overload for Point object. b) Overload the operator +, which can add x and y coordinate of two Point Objects, and return a new temporary Point object. c) Overload the operator +, which can add an integer to x and y coordinate of Point Objects, and return a new temporary Point object. d) Overload the operator += to update x and y coordinate of Point, which can add x and y of a Point to x and y coordinate of another Point. e) Overload the operator += to update x and y coordinate of Point, which can add an integer to x and y coordinate of Point. Use following main() to test your class. Output from given main: (user input in bold) (4,6) (13,14) (3,4) (1,2) (4,6) (4,6) (1,2) (14,16) (14,16)
