std::bitset<N>::reset: std::bitset<N>::reset

NAME

std::bitset<N>::reset - std::bitset<N>::reset

Synopsis


bitset<N>& reset(); (until C++11)
bitset<N>& reset() noexcept; (1) (since C++11)
bitset<N>& reset( std::size_t pos ); (2)


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 <iostream>
  #include <bitset>


  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
