Slip 23 - B) Create a C++ class Complex Number with data members real and imaginary. Write necessary functions: i. To accept Complex Number using constructor. ii. To display Complex Number in format[x + iy]. iii. To add two Complex Numbers by using friend function.

Solution:

#include<iostream>

using namespace std;

class Complex{

public:

    int real;

    int imag;

     /* Function to set the values of

      * real and imaginary part of each complex number

      */

     void setvalue()

    {

        cin>>real;

        cin>>imag;

    }

/* Function to display the sum of two complex numbers */

    void display()

    {

        cout<<real<<"+"<<imag<<"i"<<endl;

    }

/* Function to add two complex numbers */

 

    void sum(Complex c1, Complex c2)

    {

        real=c1.real+c2.real;

        imag=c1.imag+c2.imag;

    }

    };

int main()

    {

        Complex c1,c2,c3;

        cout<<"Enter real and imaginary part of first complex number"<<endl;

        c1.setvalue();

        cout<<"Enter real and imaginary part of second complex number"<<endl;

        c2.setvalue();

        cout<<"Sum of two complex numbers is"<<endl;

        c3.sum(c1,c2);

        c3.display();

    return 0;

    }
