GCC STL 边界检查
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 [].
