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 (Bounds 2) profile from the C++ Core Guidelines.
Optionally, this check can generate fixes using gsl::at
for indexing.
Options¶
- 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”.
- IncludeStyle¶
A string specifying which include-style is used, llvm or google. Default is llvm.
