std::vector<bool,Allocator>::flip
Defined in header <vector> | ||
|---|---|---|
void flip(); | (constexpr since C++20) |
Toggles each bool (replaces with its opposite value) in the vector.
Example
#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
