Answer 1

It's a const pointer to a const C string. This means that neither the contents of the string, nor the pointer itself, can be changed.

Answer 2

const protects his left side, unless there is nothing to his left and only then it protects his right side.

Applying this to your example, it's a const pointer to a const String.
