Defined in header <vector>
void flip();		(until C++20)
constexpr void flip();		(since C++20)

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

Parameters

(none)

Return value

(none)

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
