std::bitset::set(3)	       C++ Standard Libary	     std::bitset::set(3)

NAME
     std::bitset::set - std::bitset::set

Synopsis
	bitset&  set(); 				     (1) (noexcept since
     C++11)
							       (constexpr  since
     C++23)
	bitset&  set( std::size_t pos, bool value = true ); (2) (constexpr since
     C++23)

	Sets all bits to true or sets one bit to specified value.

	1) Sets all bits to true.
	2) Sets the bit at position pos to the value value.

Parameters
	pos   - the position (counting from 0, i.e. from  least  significant  to
     most
		significant) of the bit to set
	value - the value to set the bit to

Return value
	*this

Exceptions
	2)  Throws std::out_of_range if pos does not correspond to a valid posi-
     tion within
	the bitset.

Example
     // Run this code

      #include <bitset>
      #include <cstddef>
      #include <iostream>

      int main()
      {
	  std::bitset<8> b;
	  std::cout << b << '\n';
	  std::cout << b.set() << '\n';
	  std::cout << b.reset() << '\n';

	  for (std::size_t i = 1; i < b.size(); i += 2)
	      b.set(i);

	  std::cout << b << '\n';
      }

Output:
      00000000
      11111111
      00000000
      10101010

	Defect reports

	The following behavior-changing defect	reports  were  applied	retroac-
     tively 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
