C++ Program Using Operator Overloading-Add Complex Numbers

This is a sample program on operator overloading. Using operator overloading, here we add two complex numbers.


#include <iostream.h>
#include <conio.h>
#include <iomanip.h>

class complex
{
    private:

       double real, img;

    public:

       complex ( )
         {
             real = img = 0.0;
         }

       void read ( )
         {
             cout<<"\n Enter Real & Imaginary Part: ";
             cin >> real >> img;
         }

       complex operator + (complex cc2)
         {
             complex temp;
             temp.real = real + cc2.real;
             temp.img = img + cc2.img;
             return (temp);
         }

       void show ( )
         {
             cout<<"The Sum Is: "<<'\n';
             if (img > 0)
                  cout<<real << "+" << img << "i" << endl;
             else
                  cout << real << img << "i" << endl;
         }

};

int main ( )
{
    clrscr ( );
    complex c1, c2, c3;
    cout << "\n Enter Complex Number C1";

    c1.read ( );
    cout << "\n Enter Complex Number C2";

    c2.read ( );
    c3 = c1 + c2;
    c3.show ( );

    getch ( );
    return 0;
}


OUTPUT:

Enter Complex Number C1
Enter Real & Imaginary Part:
5
6

Enter complex number C2
Enter Real & Imaginary Part:
2
4

The Sum Is: 7+10i
