Create two classes, HUSBAND (Family Member 1) and WIFE (Family Member 2). Make WIFE as friend class of HUSBAND. The structure of classes are given below.

class WIFE;

class HUSBAND

{

private:

                string Husband_fname;

                string Husband_lname;

                int Husband_income;

public:

                HUSBAND(string f1, string l1, int inc):Husband_fname(f1), Husband_lname(l1), Husband_income(inc);

                HUSBAND();

                {

                //            Default initializations of data members

                }

                int getIncome();

               

};

class WIFE

{

private:

                string Wife_fname;

                string Wife_lname;

                int Wife_income;

                int tax_rate;

public:

                WIFE(string f2, string l2, int inc, int tr) ;

                WIFE()

                {

                                //Default initializations of private data members;

                }

                float calcTax(HUSBAND &f);

               

                float getTaxRate();

               

                int getIncome();

               

};

int main()

{

                HUSBAND obj1("Albert","John",55026);

                WIFE obj2("Mary","Chin",120000,5);

//Task1: Display the tax rate;

// Task2: Display income of HUSBAND;

// Task3: Display income of WIFE;

// Task4: Display total family income;

// Task5: Display total Tax Amount;

                system("pause");

                return 0;

}
