std::bitset::reset(3)

NAME
std::bitset::reset - std::bitset::reset

Synopsis
   bitset& reset(); (1) (noexcept since C++11)
                        (constexpr since C++23)
   bitset& reset( std::size_t pos ); (2) (constexpr since C++23)
   Sets bits to false.
   1) Sets all bits to false
   2) Sets the bit at position pos to false.

Parameters
   pos - the position of the bit to set

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 <iostream>
 int main()
 {
     std::bitset<8> b(42);
     std::cout << "Bitset is " << b << '\n';
     b.reset(1);
     std::cout << "After b.reset(1): " << b << '\n';
     b.reset();
     std::cout << "After b.reset(): " << b << '\n';
 }

Output:
 Bitset is 00101010
 After b.reset(1): 00101000
 After b.reset(): 00000000
