Sorted by: 5. With. auto b3 = f.get_b1_ref (); the deduced type will not be a reference, only the base type bitset<4>. This means b3 is not a reference, and all modifications of b3 or its contents will be limited to the b3 object itself. To get a reference you need to explicitly use & in the declaration: auto& b3 = f.get_b1_ref ();

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.
