...............

Write a C++ program in which you are required to define a class named Citizen. The class must include the following two data members.

// data member for Citizen Name
1: Name

//data member for Citizen Nationality
2: Nationality

Your Program should define three constructors for the class Citizen

1: a constructor with no parameter
2: a constructor with two parameters (name, nationality)
3: a copy constructor

All of these three constructors are meant to initialize their respective objects. Incase of copy constructor, you are required to assign a separate space for the data members of the new object while copying the values of previously existed object.

Declare three objects (1 for each type of constructor) in main.

Write a function in class Citizen to display the initialized data members for each object.

Also write destructor for the class Citizen. Display a message that says “destructor called” in the destructor body.

Note:- Make use of comments in source code where you use constructors , objects, copy constructors and destructors.

OUTPUT

Your output should be similar to the following

Farhan
Pakistani
_________________
Mark
Australian
_________________
Mark
Australian
_________________

Where;
Farhan
Pakistani

are the initialized against the constructor with no parameters.

Mark
Australian

are the initialized values against the constructor with two parameters.

Mark
Australian

are the initialized values against the copy constructor that copies the values of already existed object.
