Answer 1

There are quite a lot correct answers here but you may find it hard to remember, here is a trick to memorize this :

1> when const is on the left hand side of *, it means the pointer points to a constant object;

e.g.const int * p means the int cannot be changed via pointer p

2> when const is on the right hand side of *, it means the pointer is a const pointer;

e.g.int * const p means p is a constant pointer which cannot be changed.

BTW if you have const on both side of *, then it means it's a const pointer and you cannot change the object via the pointer.

e.g. int const * const p
