Write a program overloading arithmetic operators to add two complex numbers using oops c++

Sure, here is a simple C++ program that overloads arithmetic operators to add two complex numbers:

#include<iostream>
using namespace std;

class Complex {
private:
    int real, imag;
public:
    Complex(int r = 0, int i =0)  {real = r;   imag = i;}

    // This is automatically called when '+' is used with
    // between two Complex objects
    Complex operator + (Complex const &obj) {
         Complex res;
         res.real = real + obj.real;
         res.imag = imag + obj.imag;
         return res;
    }
    void print() { cout << real << " + i" << imag << endl; }
};

int main()
{
    Complex c1(10, 5), c2(2, 4);
    Complex c3 = c1 + c2; // An example call to "operator+"
    c3.print();
}

In this program, we define a class Complex to represent complex numbers. We then overload the + operator to add two Complex objects. The operator+ function takes a Complex object as an argument and adds the real and imaginary parts of the caller object to the real and imaginary parts of the argument object. The result is returned as a new Complex object.
