From cppreference.com
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

#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
