60. Sensor Calibration Class

Design and implement a simple Embedded C++ class that models a calibrated sensor.

You must define a class named Sensor that stores raw sensor readings and applies a calibration offset before reporting the final value.

Requirements

1. Class Definition
   • Define a class Sensor.
2. Private Data Members
   • int rawValue — stores the most recent raw sensor reading.
   • int offset — stores the calibration offset.
3. Public Member Functions
   • void setRaw(int value)
     • Stores a new raw sensor reading.
   • void calibrate(int off)
     • Sets the calibration offset.
   • int read()
     • Returns the calibrated sensor value (rawValue + offset).
4. Main Function Behavior
   • Read three integers from standard input in the following order:
     1. Initial raw sensor value
     2. Calibration offset
     3. New raw sensor value
   • Create a Sensor object.
   • Call setRaw() using the initial raw value.
   • Call calibrate() using the offset.
   • Call setRaw() again using the new raw value.
   • Print the final calibrated sensor reading using read().

Input Format

Three signed integers provided via standard input, each separated by a newline:

raw
offset
newRaw

Output Format

A single integer printed to standard output:

calibrated_value 

Example Input

100
-5
120

Example Output

115

Explanation

The final calibrated reading is:

120 + (-5) = 115

Constraints

• rawValue and offset must be private.
• These variables may only be modified using class member functions.
• Signed integer arithmetic is used.
• No overflow handling is required beyond standard C++ int behavior.
• Output must match exactly with no extra spaces or newlines.
