From cppreference.com
 
 
 
std::vector<bool>
(until C++20)(until C++20)(until C++20)(until C++20)(until C++20)
 
Defined in header <vector>
void flip();
(constexpr since C++20)

Toggles each bool (replaces with its opposite value) in the vector.

[edit] Example

Run this code
#include <iostream>
#include <vector>
 
void print(const std::vector <bool>& vb)
{
 for (const bool b : vb)
 std::cout << b;
 std::cout << '\n';
}
 
int main()
{
 std::vector <bool> v{0, 1, 0, 1};
 print(v);
 v.flip();
 print(v);
}

Output:

0101
1010
