int actuatorValue = sensorValue * 2;
actuator->setValue(actuatorValue);
}
};
int main() {
// Initialize sensor and actuator
Sensor* sensor = new Sensor();
Actuator* actuator = new Actuator();
// Initialize controller
Controller* controller = new Controller(sensor, actuator);
// Read sensor value from user
int value;
cout << 'Enter sensor value: '; cin >> value;
sensor->setValue(value);
// Process sensor value and update actuator value
controller->process();
// Display actuator value
cout << 'Actuator value: ' << actuator->getValue() << endl;
// Clean up
delete sensor;
delete actuator;
delete controller;
return 0;
}
Example Output:
Enter sensor value: 10
Actuator value: 20
Example Detailed Explanation:
This program demonstrates the use of C++ for embedded systems to control a simple sensor and actuator. The program follows best practices in coding and demonstrates the use of object-oriented programming.
The program consists of three classes: Sensor, Actuator, and Controller. The Sensor class represents a sensor that can read a value, while the Actuator class represents an actuator that can be controlled by setting a value. The Controller class is responsible for processing the sensor value and generating the actuator value.
In the main function, the program starts by creating instances of the Sensor, Actuator, and Controller classes. The user is prompted to enter a sensor value, which is then set in the sensor object. The Controller’s process method is called to process the sensor value and generate the actuator value, which is then displayed to the user.
Finally, the program cleans up by deleting the dynamically allocated objects.
Overall, this program demonstrates the use of C++ in an embedded system context and showcases best practices in coding, including the use of classes, encapsulation, and dynamic memory management.
