Sensor Calibration Class

#include <iostream>
using namespace std;

// Define Sensor class here
// <write your code>

class Sensor {
    private: 
     int rawValue;
     int 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;
}
