14. Sensor with Thresholds Class

 Frame a class Sensor with the following:

• Private data members:
  • id (integer, sensor ID)
  • value (integer, current reading)
     
• Public methods:
  • Constructor Sensor(int id, int value)
  • void setValue(int v) → updates the reading
  • bool isAboveThreshold(int t) const → returns true if value >= t
  • int getId() const → returns the sensor ID
     

The input will contain:

• n (number of sensors)
• followed by n lines, each: id value threshold
   For each sensor, print either:

Sensor <id>: ALERT

or

Sensor <id>: NORMAL

depending on whether the reading meets/exceeds the threshold.

Example
 Input:

3
101 75 60
202 30 50
303 100 100

 Output:

Sensor 101: ALERT
Sensor 202: NORMAL
Sensor 303: ALERT

Here, n = 3. For the first line: id = 101, value = 75, threshold = 60.
Explanation:

• For 101: 75 ≥ 60 → ALERT
• For 202: 30 < 50 → NORMAL
• For 303: 100 ≥ 100 → ALERT
   

Input:

2
1 0 1
2 255 128

Output:

Sensor 1: NORMAL
Sensor 2: ALERT

Explanation:

• 1: 0 < 1 → NORMAL
• 2: 255 ≥ 128 → ALERT
