WebApr 6, 2024 · To create a vector in C++, you need to include the header file and declare a vector object. Here's an example: #include std::vectormy_vector. You can add elements to the vector using the push_back () method: my_vector.push_back (1); my_vector.push_back (2); You can access elements in the vector using the [] … WebAug 21, 2024 · Unfortunately std::bitset does not have suitable design for what you want.. It is not designed an aggregate (like std::array is) so aggregate initialiation is impossible (and also copying bits into it with std::memcpy is undefined behavior).. It can take only one unsigned long long in constexpr constructor.. The operator [] and set method will become … shark vacuum cleaner weight
