Web15. As of C++11, you can ask a vector or deque to return unneeded memory to the system by calling member function shrink_to_fit. This requests that the container reduce its capacity to the number of elements in the container. According to the C++ standard, implementations can ignore this request so that they can perform implementation-specific optimizations.

A few choices that can/could work would be: Set an upper bound on the size, use a bitset of that size, and just ignore the extra bits. Switch to an std::vector. This has caveats, but provides roughly similar basic capabilities as a bitset. simpson pressure washer parts near me
