const TypedeffedIntPointer not equal to const int *

Question

I have the following C++ code:

typedef int* IntPtr;
const int* cip = new int;
const IntPtr ctip4 = cip;

I compile this with Visual Studio 2

Answer 1

const IntPtr is the same as int* const, not const int*.

That is, it is a const pointer to an int, not a pointer to a const int.

A solution would be to provide two typedefs:

typedef int* IntPtr;
typedef const int* ConstIntPtr;

and use ConstIntPtr when you need a pointer to a const int.
