Helper classes

std::hash (C++11)

bitset<N>& reset();	(1)
bitset<N>& reset( 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

1)

(none)	(until C++11)
noexcept specification: noexcept	(since C++11)

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
