cppcoreguidelines-pro-bounds-constant-array-index
=================================================

This check flags all array subscript expressions on static arrays and
``std::arrays`` that either do not have a constant integer expression index or
are out of bounds (for ``std::array``). For out-of-bounds checking of static
arrays, see the clang-diagnostic-array-bounds check.

The check can generate fixes after the option
``cppcoreguidelines-pro-bounds-constant-array-index.GslHeader`` has been set to
the name of the include file that contains ``gsl::at()``, e.g. ``"gsl/gsl.h"``.

This rule is part of the "Bounds safety" profile of the C++ Core Guidelines, see
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Pro-bounds-arrayindex.
