constant pointer c++
int* // pointer to int
int const * // pointer to const int
int * const // const pointer to int
int const * const //const pointer to const int
// Now the first const can be on either side of the type so:
const int * == int const *
const int * const == int const * const
// If you want to go really crazy you can do things like this:
int ** // pointer to pointer to int
int ** const // a const pointer to a pointer to an int
int * const * // a pointer to a const pointer to an int
int const ** // a pointer to a pointer to a const int
int * const * const // a const pointer to a const pointer to an int
