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

Const pointer could mean a few different things. I recommend checking out the C++ FAQ Lite on the matter.

You can have:

const int* p;
int* const p;
const int* const p;

All three mean different things. Yes, it's kind of confusing.

In your case, you have the second, which means you have a constant pointer to a non-constant object. That is, you can change the value of the integer via the pointer, but you can't change what the pointer points to. So the code you posted would not be legal.
