Suppose that class Y is a friend of class X, meaning that the member functions of class Y have access to all the members of class X. Should the friend key word appear in class Y’s declaration or in class X’s declaration?
Suppose that the binary operator + is overloaded as a member function of the class myClass, to add the corresponding members of two objects of type myClass, and object1 and object2 are objects of type myClass. Consider the following expression:
object1 + object2
The compiler translates this expression into which expression?
a. Extend the definition of the class complexType so that it performs the subtraction and division operations. Overload the operators subtraction and division for this class as member functions.
If (a, b) and (c, d) are complex numbers,
(a, b) - (c, d) = (a - c, b - d),
If (c, d) is nonzero,
(a, b)/(c, d) = ((ac + bd)/(c ^2+ d ^2 ), (-ad + bc)/(c ^2 + d^ 2 ))
b. Write the definitions of the functions to overload the operators – and / as defined in part a.
c. Write a test program that tests the various operations on the class complexType. Format your answer with two decimal places

- Is it legal to have an abstract class with all member functions pure virtual?arrow_forwardc++ Implement a MyInt class. An object in the MyInt class must be able to hold a single dynamically allocated integer. MyInt should have the following members: A member variable ptr of type int *.A parameterized constructor that takes nums of type int as input parameters.A destructor.A superimposed assignment operator (). The copy must be deep.A function set that sets the value of the number.A function get that returns the value of the number.The members must be encapsulated in accordance with the convention. Memory leaks must be avoided. To test your class, create objects and call functions according to the comments below. All tests must be validated.
