GPIO Pin Operator Overload

#include <iostream>
using namespace std;

// Define enum class Level
enum class Level { LOW = 0, HIGH = 1 };
// Define class GpioPin with operator= and operator int()
class GpioPin{
    Level level;
    public:
        explicit GpioPin(Level l): level(l){}
        GpioPin& operator=(Level l){
            level = l;
            return *this;
        }
        operator int() const{
            return static_cast<int>(level);
        }
};

int main() {
    int init, next;
    cin >> init >> next;

    GpioPin pin(static_cast<Level>(init));

    pin = static_cast<Level>(next);

    cout << pin;

    return 0;
}
