Sets all bits to true
or sets one bit to specified value.
true
.pos
to the value value
.pos | - | the position (counting from 0, from least significant to most significant) of the bit to set |
value | - | the value to set the bit to |
*this

#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:
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
DR | Applied to | Behavior as published | Correct behavior |
---|---|---|---|
LWG 186 | C++98 | the type of value was int | corrected to bool |
sets bits to false (public member function) |
|
toggles the values of bits (public member function) |
