Code Explanation:

The C++ program is designed to simulate real-time data sampling and processing for a medical device, such as a patient monitoring system. The program uses multi-threading, synchronization, and condition variables to handle concurrent operations.

• The SensorData struct represents the structure of the data collected by the sensors.
• Two global functions, sampleData() and processData(), simulate the data sampling and processing tasks, respectively.
• In sampleData(), we simulate sensor data collection, and in processData(), we process the collected data, such as checking for abnormal values.
• We use a std::vector<SensorData> as a shared buffer between threads and a std::condition_variable to signal the availability of new data to the processing thread.
• The sampleData() function pushes simulated data to the buffer and notifies processData() through the condition variable.
• The processData() function waits for new data and processes it once the condition variable is notified; it simulates processing time to mimic real system behavior.
• Mutex and lock guards are used to ensure that shared resources (the data buffer and I/O operations) are accessed in a thread-safe manner.
• The main() function sets up the threads for data sampling and processing, and for demonstration purposes, the threads run for a short time and then detach.
• The expected output prints out messages for any out-of-range temperature or abnormal heart rate values, indicating simple data validation checks. A message indicates the end of the simulation.

The architecture of the program demonstrates the use of concurrent programming techniques that are critical in developing real-time systems for medical devices, where timely and synchronized data handling is paramount.
