Some questions about "this" pointer:

1. To make an assignment function,

Stribg &String::operator=(const String &other)
{
    ...
    return *this;
}

I have hard time to understand why "*this" matches a "String &" here. Could
someone shed some light on this?

2. In a static member function aren't there "this" pointer accessible inside
it?

3. In a const member function is the "this" pointer of const type while
non-const type in a non-const member?

Thanks in advance!
