Making a pointer more like an array

As an aside, the fp defined above can be changed to point to anything, which doesn’t make sense for the starting address of an array. It makes more sense to define it as a constant, so any attempt to modify the pointer will be flagged as an error. To get this effect, you might try

int const* q = new int[10];


const int* q = new int[10];

but in both cases the const will bind to the int, that is, what is being pointed to, rather than the quality of the pointer itself. Instead, you must say

int* const q = new int[10];

Now the array elements in q can be modified, but any change to q (like q++) is illegal, as it is with an ordinary array identifier.
