Std::bitset::reset (3) Linux Manual Page

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
