89. Sensor Packet Handling

You must define a class Packet that represents a small telemetry packet sent from a sensor module.

Your class must:

1. Store the following private members:
   • int id
   • int temperature
   • int humidity
2. Provide:
   • A constructor that sets id and initializes temperature and humidity to 0
   • A method void update(int t, int h)
     • Updates temperature and humidity
   • A method void print()
     • Prints the packet contents in the format:

       • ID=<id> TEMP=<temperature> HUM=<humidity>

3. In main():
   • Read id, t1, h1, t2, h2
   • Create a Packet object with the given id
   • Call update(t1, h1)
   • Call update(t2, h2)
   • Print the final packet using print()

Example Input:

7 20 40 25 45

Example Output:

ID=7 TEMP=25 HUM=45 

Constraints:

• All data members (id, temperature, humidity) must be private
• Constructor must initialize temperature and humidity to 0
• Print format must match exactly
