Using a common friend function, perform multiplication operation between x and y.(4 marks)

Solve any one question from Q.2(c) & Q.2(d)

2(c) Create a class coordinate containing x, y and z private variables. Perform operations for incrementing, adding and comparing object(s) by overloading + +, + = and = = operators respectively. Define necessary functions to set and display the variables.(7 marks) 2(d) Write a program to demonstrate conversion of an object of one class into an object of another class.(7 marks)
