3. Private Access

Your task is to define a class named Sensor with:

• A private variable value (type int).
• A public method setValue(int v) to set it.
• A public method getValue() to return it.
  
   

The program will:

1. Create a Sensor object.
2. Call setValue(75).
3. Print Sensor value: 75.
    

Example

Output:

Sensor value: 75

Why this output?

The private variable is set through the setter method and read through the getter.
