GPIO Pin Class

#include <iostream>
using namespace std;

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

    GpioPin()
    {
        pin_state=0; 
    }

    void write(int value);
    int read();
};

void GpioPin::write(int value)
{
    pin_state = value;
}

int GpioPin::read()
{
    return pin_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;
}
