问题描述
如何为 operator[]
和迭代器启用边界检查?
How do I enable bound checking for operator[]
and iterators?
推荐答案
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 []
.
