Operator Overloading Example in C++


This code defines a class Complex which represents a complex number with a real and an imaginary part. The class has a constructor, which initializes the real and imaginary parts of the complex number, and an operator+ function which overloads the + operator for two complex numbers. The operator+ function takes another complex number c as input, and returns a new complex number which is the sum of the two complex numbers.

In the main function, two complex numbers c1 and c2 are initialized with real and imaginary values. Then, the + operator is used to add c1 and c2 and store the result in c3. Finally, the real and imaginary parts of c3 are printed.

Source Code

#include<iostream>
using namespace std;

class Complex
{
public :
    int real;
    int img;


    Complex operator +(Complex c)
    {
        Complex temp;
        temp.real=real+c.real;
        temp.img=img+c.img;
        return temp;
    }

};

int main()
{
    Complex c1,c2,c3;
    c1.real=5;
    c1.img=3;
    c2.real=10;
    c2.img=5;
    c3=c1+c2;
    cout<<"\nReal : "<<c3.real;
    cout<<"\nImg : "<<c3.img;
    return 0;
}
