Toggle Bitmask

#include <iostream>
#include <cstdint>
using namespace std;

class Flags {
private:
    uint8_t bits;
public:
    explicit Flags(uint8_t b) : bits(b) {}

    // Define operator~ to return a new Flags object with all 8 bits inverted
    friend Flags operator~(const Flags& f){
        Flags new_flags(~(f.bits));
        return new_flags;
    }

    uint8_t getBits() const {
        return bits;
    }
};

int main() {
    int val;
    cin >> val;

    Flags f(static_cast<uint8_t>(val));
    Flags toggled = ~f;

    cout << "Input=" << val
         << " Toggled Input=" << static_cast<int>(toggled.getBits());

    return 0;
}
