Sensor Calibration Class

#include <iostream>
using namespace std;

// Define Sensor class here
// <write your code>
class Sensor{
    private:
        int rawValue,offset;
    public:
        void setRaw(int value){rawValue = value;}
        void calibrate(int off){offset = off;}
        int read(){ return rawValue + offset;}
};

int main() {
    int raw, offset, newRaw;
    cin >> raw >> offset >> newRaw;

    Sensor s;
    s.setRaw(raw);
    s.calibrate(offset);
    s.setRaw(newRaw);

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