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)

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
