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) : id(sensorId), offset(calibrationOffset), lastValue(0){}
    void update(int raw) {
        lastValue = raw + offset;
    }

    int read() {
        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;
}
