std::bitset<N>::set
(1) | ||
bitset& set(); |
(until C++11) | |
bitset& set() noexcept; |
(since C++11) | |
bitset& set( std::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 (least significant to most significant) |
value | - | the value to set the bit to |
Return value
*this
.
Exceptions
Example
#include <iostream> #include <bitset> int main() { std::bitset<8> b; std::cout << b << '\n'; std::cout << b.set() << '\n'; std::cout << b.reset() << '\n'; for (size_t i = 1; i < b.size(); i += 2) { b.set(i); } std::cout << b << '\n'; }
Output:
00000000 11111111 00000000 10101010
