SensorConfig Initialization

#include <iostream>
using namespace std;

// Define SensorConfig class here
class SensorConfig{
    private:
    int id;
    int offset;
    int lastValue;

    public:
    SensorConfig(int sensorId, int calibrationOffset) noexcept : id(sensorId), offset(calibrationOffset), lastValue(0) {};
    void update(int raw) noexcept 
    {
        lastValue =  raw + offset;
    }
    int read() noexcept
    {
        return lastValue;
    }
};
int main() {
    int id, offset;
    cin >> id >> offset;

    SensorConfig cfg(id, offset);  // must use parameterized constructor

    int r1, r2;
    cin >> r1 >> r2;

    cfg.update(r1);
    cfg.update(r2);

    cout << cfg.read();
    return 0;
}
