std::bitset::flip(3)

💅 std::bitset::flip(3) — C++ Standard Libary, bestie 💅

okay so this is std::bitset::flip, straight from the C++ Standard Libary (yes, that's the manual name right there), and it is literally the glow-up button for your bits. true becomes false, false becomes true — no cap, it's a logical NOT for part or all of the bitset. ✨

🎀 NAME 🎀

• std::bitset::flip - std::bitset::flip — yes bestie, that's the whole name, it's giving self-titled era 💅

🌸 Synopsis 🌸

bitset& flip();                  (1) (noexcept since C++11)
                                             (constexpr since C++23)
bitset& flip( std::size_t pos ); (2) (constexpr since C++23)

okay so overload (1) flips all the bits — like operator~, but in-place. Overload (2) flips the bit at the position pos. Both are out here doing the most useful little bit inversion. 🦋

🍓 Parameters 🍓

• pos — the position of the bit to flip

👑 Return value 👑

*this — that's it, that's the return value, and it's iconic.

💀 Exceptions 💀

Overload 2) throws std::out_of_range if pos does not correspond to a valid position within the bitset. That's the danger zone, bestie — if pos is not valid, it is not gonna be cute.

🔥 Example 🔥

// Run this code

#include <bitset>
#include <iostream>

int main()
{
    std::bitset<4> flops;

    std::cout << flops << '\n'
              << flops.flip(0) << '\n'
              << flops.flip(2) << '\n'
              << flops.flip() << '\n';
}

🌈 Output: 🌈

0000
0001
0101
1010
