Question

In C++,

Create a class COMPLEXNUM, each has two private member data, ipart and rpart, both are doubles. Create three COMPLEXNUM objects, for the first two set the ipart and rpart either manually or from the keyboard (you pick) then create a function with this structure:

COMPLEXNUM ADDTWO(COMPLEXNUM CN1, COMPELXNUM CN2);

Add the rparts and add the iparts from them set the sums as data in the third COMPLEXNUM and return it to main(), then display all three to the screen, something like this:

CN1 rpart = 4 ipart = 3

CN2 rpart = 5 ipart = -1

CN3 rpart = 9 ipart = 2

#include<iostream>

using namespace std;

class COMPLEXNUM{

    private:

       

        double ipart;

        double rpart;

       

    public:

       

        // constructor

        COMPLEXNUM()

        {

            this->ipart = 0.0;

            this->ipart = 0.0;

        }

       

        // constructor

        COMPLEXNUM(double r, double i)

        {

            this->ipart = r;

            this->ipart = i;

        }

       

        // setter method

        void setReal(double r)

        {

            this->rpart = r;

        }

       

        void setImaginary(double i)

        {

            this->ipart = i;

        }

       

        // getter method

        double getReal()

        {

            return this->rpart;

        }

};

COMPLEXNUM ADDTWO(COMPLEXNUM CN1, COMPLEXNUM CN2)

{

    // calculate real part

    double r = CN1.getReal() + CN2.getReal();

   

    // calculate imaginary part

    double i = CN1.getImaginary() + CN2.getImaginary();

   

    // calculate the resultant object

    COMPLEXNUM ans(r, i);

   

    return ans;

}

void display(COMPLEXNUM CN)

    cout<<"rpart = "<<CN.getReal()<<" ipart = "<<CN.getImaginary()<<endl;

}

int main()

    display(CN1);
