如何为 operator[]
和迭代器启用边界检查?
How do I enable bound checking for operator[]
and iterators?
您可以通过使用 -D_GLIBCXX_DEBUG
进行编译来激活运行时迭代器和边界检查.另请注意,随机访问容器除了 operator []
外,还提供始终边界检查的 at()
操作.
You can activate runtime iterator and bounds checking by compiling with -D_GLIBCXX_DEBUG
. Also note that random-access containers provide the always bounds-checking at()
-operation in addition to operator []
.

at() 操作:std::vector::at()
, std::deque::at()
和 std::array::at()
at() operation: std::vector::at()
, std::deque::at()
and std::array::at()
