In The Name Of ALLAH
Advanced Programming - Homework 2
Dr.Amir Jahanshahi
Deadline: Friday, 13 Farvardin - 23:00
# Introduction
In this homework, you'll be implementing a **super!** smart room in C++. This room has a **DHT11** sensor to measure both temperature and humidity. Let's see.
**Note**: You must not remove any keyword in variables and functions definitions, but you can add some keywords wherever necessary.
# Room Class
This class represents our room. It has the following member functions and member variables.
```c++
class Room{
private:
size_t id;
double temperature{28};
double humidity{95}; // Make this as last 2 digits of your student no
std::unique_ptr dht;
public:
Room(size_t id, double temperature, double humidity);
double getTemperature() const;
double getHumidity() const;
void changeTemperatureStdev(double stdev);
void changeHumidityStdev(double stdev);
};
```
Names of variables and functions are clear about their application. You only need to know about the **DHT11** class now.
# DHT11 Class
This class represents the sensor. It has a pointer to the room to get the temperature and humidity. But, as every sensor has, this sensor has some measurement noise. So it gets measurements as a **Normal** random variable with the specified mean (from the room class) and specified standard deviation. Let's see contents of this class.
```c++
class DHT11{
private:
double temp_stdev{1};
double hum_stdev{1};
Room* proom;
public:
DHT11(double temp_stdev, double hum_stdev);
DHT11(double temp_stdev, double hum_stdev, Room* proom);
double getTemperature() const;
double getHumidity() const;
};
```
**Question 1**: What would you do for your code to be able to run the next block successfully? Explain and do it!
```c++
const Room r2(2, 35, 50);
r2.changeHumidityStdev(83);
std::pair p{r2.
dht->getStdevs()};
std::cout<
