GPIO Pin Class

#include <iostream>
using namespace std;

// Define class GpioPin here
// <write your code>
class GpioPin{
    public:
    int pinNumber;
    int state;

    GpioPin()
    :state(0) {}


    void write (int value)
    {
        this->state = value;
    }

    int read()
    {
        return state;
    }
};


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;
}
