GPIO Pin Operator Overload

#include <iostream>
using namespace std;

// Define enum class Level
enum class Level { LOW = 0, HIGH = 1};
class GpioPin{
    Level lvl;

    public:
    GpioPin(Level l): lvl(l){}

    GpioPin& operator=(Level next){
        lvl = next;
        return *this;
    }
    operator int() const{
        return static_cast<int>(lvl);
    }
};
// Define class GpioPin with operator= and operator int()

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

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

    pin = static_cast<Level>(next);

    cout << pin;

    return 0;
