NAME

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

Synopsis

bitset& reset(); (until C++11)
bitset& reset() noexcept; (since C++11)
(1) (until C++23)
constexpr bitset& reset() noexcept; (since C++23)
bitset& reset( std::size_t pos ); (2) (until C++23)
constexpr bitset& reset( std::size_t pos ); (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 <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
