[18.5] What's the difference between "const Fred* p", "Fred* const p" and "const Fred* const p"?
You have to read pointer declarations right-to-left.
const Fred* p means "p points to a Fred that is const" — that is, the Fred object can't be changed via p.
Fred* const p means "p is a const pointer to a Fred" — that is, you can change the Fred object via p, but you can't change the pointer p itself.
const Fred* const p means "p is a const pointer to a const Fred" — that is, you can't change the pointer p itself, nor can you change the Fred object via p.
