GPIO Pin Class

#include <iostream>
using namespace std;

// Define class GpioPin here
class GpioPin{
    public:
        int pinNumber;
        int pinState;

        GpioPin(){
            pinState = 0;
        }

        void write(int value){
            pinState = value;
        }

        int read(){
            return pinState;
        }
};

int main() {
    int pin, initialValue, finalValue;
    cin >> pin >> initialValue >> finalValue;

    GpioPin gpio;          // default constructor
    gpio.pinNumber = pin; // manual assignment

    gpio.write(initialValue);
    gpio.write(finalValue);

    cout << "GPIO Pin " << gpio.pinNumber
         << " State " << gpio.read();

    return 0;
}
