class complex
{
    int i;
    int j;
    public:
    complex(){}
    complex(int a, int b)
    {
        i = a;
	j = b;
    }
     complex operator+(complex c)
     {
	complex temp;
	temp.i = this->i + c.i;
	temp.j = this->j + c.j;
	return temp;
    }
     void show(){
	cout<<"Complex Number: "<<i<<" + i"<<j<<endl;
    }
};
int main(int argc, char const *argv[])
{
    complex c1(1,2);
    complex c2(3,4);
    complex c3 = c1 + c2;
    c3.show();
    return 0;
