How can I activate bounds checking for the GCC STL?

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.

• "at()" Operation: std::vector::at(), std::deque::at(), and std::array::at()
