Title: Implement a class Complex which represents the Complex Number data type. Implement the following operations: 1. Constructor (including a default constructor which creates the complex number0+0i). 2. Overloaded operator+ to add two complex numbers. 3. Overloaded operator* to multiply two complex numbers. 4. Overload << and >> to print and read Complex Numbers.

 #include<iostream>

using namespace std;

class complex

{

public:

    float real,img;

    complex()

    {

    real=0;

    img=0;

    }

    complex operator +(complex);

    complex operator *(complex);

    friend ostream &operator<<(ostream&,complex&);

    friend istream &operator>>(istream&,complex&);

};

complex complex::operator +(complex obj)

{

    complex temp;

    temp.real=real+obj.real;

    temp.img=img+obj.img;

    return (temp);

}

complex complex::operator *(complex obj)

{

    complex temp;

    temp.real=(real*obj.real)-(img*obj.img);

    temp.img=(real*obj.img)+(img+obj.img);

    return (temp);

}

istream &operator>>(istream& is,complex& obj)

{

    is>>obj.real;

    is>>obj.img;

    return is;

}

ostream &operator<<(ostream& os,complex& obj)

{

    os<<obj.real;

    os<<"+"<<obj.img<<"i";

    return os;

}

int main()

{

    complex a,b,c,d;

    //cout<<"\n Enter first complex number"<<endl;

    cout<<"\n Enter real and imaginary part of first complex number:";

    cin>>a;

    //cout<<"\n Enter second complex number"<<endl;

    cout<<"\n Enter real and imaginary part of second complex number:";

    cin>>b;

    cout<<"\n Arithmetic operations are :";

    c=a+b;

    cout<<"\n Addition is:"<<c;

   

    d=a*b;

    cout<<"\n Multiplication is:"<<d<<"\n";

    return 0;

}

*****************OUTPUT***************************

Enter real and imaginary part of first complex number:3 

3

 Enter real and imaginary part of second complex number:4

5

 Arithmetic operations are :

 Addition is:7+8i

 Multiplication is:-3+23i
