New to C++. Question about constant pointers

Question

I am trying to learn C++ via some web tutorials. I don\'t have a compiler available to me, otherwise I would try this out. I\'m not sure what is meant by a const pointer. Doe

Answer 1

In your code, the pointer cannot move, but the data pointed to can change.

It's legal up to the first delete. A subsequent new would not work because it's an assignment to a constant.

It's relatively unusual to see this, more common is to see where the data pointed to is unchangeable but the pointer can move.

int bar;
int baz;
const int * foo = &bar;
*foo = 4; // illegal
foo = &baz; // legal

having both pointer and value being const is common with strings

const wchar_t * const myString = L"String that will never change.";
