There are std::bitset (fixed size, allocates on the stack) and boost::dynamic_bitset (dynamic size, allocates from stack and heap) https://www.boost.org/doc/libs/1_68_0/libs/dynamic_bitset/dynamic_bitset.htm... The latter also has more sensible implementations of operator& and operator|. Before you invent a new thing, what is wrong with these classes? Best regards, Hans
