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.
