Sensor Calibration Class

#include <iostream>
using namespace std;

class Sensor{
     private:
        int rawValue;
        int offset;
     public:
        void setRaw(int value){
             rawValue = value;//this->rawValue = off;
        }
        void calibrate(int off){
             offset = off;//this->offset = off;
        }
        int read(){
            return offset + rawValue;
        }
};

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;
