Goal: Learn how to implement subclasses.

Assignment: You are developing a smart home system focused on energy efficiency. Part of this system is a smart thermostat that manages heating and cooling cycles to optimize energy usage. The software for the thermostat is built upon a general framework for all the smart devices in the home, however, it needs to be altered to work with the device.

Assume the existence of a SmartDevice class, defined as such:

class SmartDevice

$\{$

private:

string deviceName;

public:

string getDeviceName$()$ return deviceName;

SmartDevice$()\{$ deviceName $=$ "General Smart Device"; $\}$

void setDeviceName$($string name$)\{$ deviceName $=$ name; $\}$

$\}$

Define a derived class, SmartThermostat, from Smart Device that contains:

A private double member called temperature

A public accessor called 'getTemperature' that takes no parameters and returns a double

A public constructor that sets temperature to $20$ degrees, and deviceName to "Smart Thermostat" $($Hint: Look at the mutators in Smart Device$)$;

Everything in here is impossible and I legitimately feel the question is incorrect. Please help me$.$
