GPIO Pin Class

#include <iostream>
using namespace std;

// Define class GpioPin here
// <write your code>
class GpioPin {
    public:
        int pinNumber;
        int pin;
        GpioPin(){pin = 0;}
        void write(int value){
            pin = value;
        }
        int read() {
            return pin;
        }
};

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;
}
