NAME¶

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

Synopsis¶

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

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
