std::bitset::set(3) C++ Standard Libary std::bitset::set(3) NAME std::bitset::set - std::bitset::set Synopsis bitset& set(); (1) (noexcept since C++11) (constexpr since C++23) bitset& set( std::size_t pos, bool value = true ); (2) (constexpr since C++23) Sets all bits to true or sets one bit to specified value. 1) Sets all bits to true. 2) Sets the bit at position pos to the value value. Parameters pos - the position (counting from 0, i.e. from least significant to most significant) of the bit to set 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 <bitset> #include <cstddef> #include <iostream> int main() { std::bitset<8> b; std::cout << b << '\n'; std::cout << b.set() << '\n'; std::cout << b.reset() << '\n'; for (std::size_t i = 1; i < b.size(); i += 2) b.set(i); std::cout << b << '\n'; } Output: 00000000 11111111 00000000 10101010 Defect reports The following behavior-changing defect reports were applied retroac- tively to previously published C++ standards. DR Applied to Behavior as published Correct behavior LWG 186 C++98 the type of value was int corrected to bool See also reset sets bits to false (public member function) flip toggles the values of bits (public member function) http://cppreference.com 2024.06.10 std::bitset::set(3)
