C++ Operator Overloading

I remember this used to seem so confusing in the past… but having played so heavily with pointers, linked lists, and manipulations therein, this suddenly wasn't any bit of a problem at all.

Working on code for a custom number class:

number & number :: operator+(const number &rhs)
{
    this -> add(rhs);
    return *this;
}
 
number & number :: operator=(const number &rhs)
{
    if (this != &rhs) // with equal, need to check for self-references
    {
        delete this;  // deallocate what we currently have
        memcpy(this, &rhs, sizeof(number)); // replace with copy 
    }
    return *this;
}
