# cppcoreguidelines-pro-bounds-pointer-arithmetic

This check flags all usage of pointer arithmetic, because it could lead to an invalid pointer. Subtraction of two pointers is not flagged by this check.

Pointers should only refer to single objects, and pointer arithmetic is fragile and easy to get wrong. `span<T>` is a bounds-checked, safe type for accessing arrays of data.

This rule is part of the Bounds safety (Bounds 1) profile from the C++ Core Guidelines.

## Options

AllowIncrementDecrementOperators

  When enabled, the check will allow using the prefix/postfix increment or decrement operators on pointers. Default is `false`.
