Question

I am building a c++ program for handling complex numbers.
I am having problem with the behaviour of this code:

Complex& Complex::operator=(const Complex& com)
{
    Complex::re_=com.re_;
    Complex::im_=com.im_;
    return *this;
}

Now, the return type of this function is a reference of Complex type. So shouldn’t I be passing this rather than *this.

Answer 1

The this pointer is the address of your object instance.

Use an asterisk to dereference it.
