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
