Write the definition for a class called complex that has floating point data members for storing real and imaginary parts. The class has the following member functions: void set(float, float) to set the specified value in object void disp() to display complex number object complex sum(complex) to sum two complex numbers & return complex number 1. Write the definitions for each of the above member functions. 2. Write main function to create three complex number objects. Set the value in two objects and call sum() to calculate sum and assign it in third object. Display all complex numbers.

 

#include <iostream>

using namespace std;

class complex

{

    int real, img;

public:

    void inputdata(int r, int i)

    {

        real = r;

        img = i;

    }

    void displaydata()

    {

        cout << real << " +i " << img;

    }

    friend complex sum(complex c1,complex c2)

    {

        complex temp;

        temp.real = c1.real + c2.real;

        temp.img = c1.img = c2.img;

        return (temp);

    }

};

int main()

{

    complex C1, C2, C3;

    C1.inputdata(5, 4);

    C2.inputdata(3, 7);

    C3 = sum(C1,C2);

    cout << "first complex number " << endl;

    C1.displaydata();

    cout << "second complex number " << endl;

    C2.displaydata();

    cout << "sum of two complex data :" << endl;

    C3.displaydata();

}

output :

5 +i 4second complex number 3 +i 7sum of two complex data : 8 +i 7
