GPIO Pin Class

#include <iostream>
using namespace std;

// Define class GpioPin here
// <write your code>

class GpioPin
{
    public:
        int pinNumber,pinstate;
        GpioPin(){pinstate = 0;}
        void write(int initialValue){pinstate = initialValue;}
        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;
}
