.. title:: clang-tidy - cppcoreguidelines-pro-bounds-constant-array-index 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 `-Warray-bounds` Clang diagnostic. 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. Options ------- .. option:: GslHeader The check can generate fixes after this option has been set to the name of the include file that contains ``gsl::at()``, e.g. `"gsl/gsl.h"`. .. option:: IncludeStyle A string specifying which include-style is used, `llvm` or `google`. Default is `llvm`.
