std::bitset::set(3) C++ Standard Libary std::bitset::set(3) NAME std::bitset::set - std::bitset::set Synopsis bitset& set(); (until C++11) bitset& set() noexcept; (since C++11) (until C++23) constexpr bitset& set() noexcept; (1) (since C++23) bitset& set( std::size_t pos, bool value = true (until C++23) ); (2) constexpr bitset& set( std::size_t pos, bool (since C++23) value = true ); Sets all bits to true or to specified value. 1) Sets all bits to true. 2) Sets the bit at position pos to the value value. Parameters pos - the position of the bit to set (least significant to most significant) value - the value to set the bit to Return value *this Exceptions 2) Throws std::out_of_range if pos does not correspond to a valid position within the bitset. Example // Run this code #include <iostream> #include <bitset> int main() { std::bitset<8> b; std::cout << b << '\n'; std::cout << b.set() << '\n'; std::cout << b.reset() << '\n'; for (size_t i = 1; i < b.size(); i += 2) { b.set(i); } std::cout << b << '\n'; } Output: 00000000 11111111 00000000 10101010 See also reset sets bits to false (public member function) flip toggles the values of bits (public member function) http://cppreference.com 2022.07.31 std::bitset::set(3)
