8.9.3 Pointer/Subscript Notation

Pointers can be subscripted exactly as built-in arrays can. For example, the expression

bPtr[1]

refers to b[1]; this expression uses pointer/subscript notation.

For clarity, use built-in array notation instead of pointer notation when manipulating built-in arrays.
