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;
}
