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?
Create a Pair class in C++ with the members x, y and also overload
the + operator to add the values of x separately and the values of y
separately for two objects of the Pair class. Also, write a
parameterized constructor for the class.
Public Members: int x, int y
Function: Overload the + operator.
Constructor: Parameterized.

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.

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.
