Activating Bound Checking for GCC STL
To ensure operators and iterators adhere to bounds constraints, enabling bound checking for the GNU C Standard Library (STL) is crucial. This safeguards against potential out-of-bounds memory access errors.
Solution:
GCC provides a flag (-D_GLIBCXX_DEBUG) specifically tailored for activating both runtime iterator and bounds checking. By compiling your code with this flag enabled, you can detect and handle memory errors in advance.
Additional Observation:
For random-access containers, which include arrays, vectors, and deque containers, an additional element access method called "at()" is available. Unlike operator [], "at()" performs bounds checking by default, providing an alternative option for accessing elements safely.
