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 {
private:
    Level level;
public:
    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;
}
