WebThe size of a std:bitset is a template parameter, so it has to be a compile-time constant. 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. WebMay 8, 2011 · You're not allowed to initialize member vars at declaration point.

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. high tea tijdstip
