std::vector::flip(3)

💖 std::vector::flip(3) 💖

okay so this page lives in the C++ Standard Libary manual — yes, that's the spelling the source uses, and we are not gaslighting you about it — and it's all about std::vector::flip. bestie, it's a tiny member function with main character energy. 💅

---

✨ NAME ✨

std::vector::flip - std::vector::flip

---

🌸 Synopsis 🌸

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) — no arguments, bestie. zero. nada. the void of parameters. 🫶

---

🦋 Return value 🦋

• (none) — it returns nothing. it's giving void energy. ✨

---

🔥 Example 🔥

okay, run this code, it's literally right there:

       // 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);
        }
