std::vector<bool,Allocator>::swap (3) - Linux Man Pages

std::vector<bool,Allocator>::swap: std::vector<bool,Allocator>::swap

NAME

std::vector<bool,Allocator>::swap - std::vector<bool,Allocator>::swap

Synopsis


Defined in header <vector>
static void swap(reference x, reference y);


Swaps the contents of x and y.

Parameters


x - std::vector<bool>::reference value to swap with y
y - std::vector<bool>::reference value to swap with x

Return value


(none)

Complexity


Constant.

Example


// Run this code


  #include <vector>
  #include <iostream>


  int main()
  {
      std::vector<bool> vb1{ 1,0 };


      for (auto e : vb1) { std::cout << e << " "; }
      std::cout << '\n';


      vb1.swap(vb1[0], vb1[1]);


      for (auto e : vb1) { std::cout << e << " "; }
  }

Output:


  1 0
  0 1
