std::bitset::set

bitset<N>& set();	(1)
bitset<N>& set( size_t pos, bool value = true );	(2)

Sets all bits to true or to specified value.

1) Sets all bits to true.

2) Sets the bit at position pos to the value value.

Parameters

pos	-	the position of the bit to set
value	-	the value to set the bit to

Return value

*this.

Exceptions

(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

#include <iostream>
#include <bitset>
 
int main()
{
    std::bitset<8> b;
    for (size_t i = 1; i < b.size(); i += 2) {
        b.set(i);
    }
    std::cout << b << '\n';
}

Output:

10101010

reset	sets bits to `false` (public member function)
flip	toggles the values of bits (public member function)
