Question

Hello! I know this has been answered before but I would love a new solution for it. This would be in C++

Create a class named Building with one public pure virtual function computerEnergyConsumption() that returns a double value of the instance variable which stores the energy consumed by the building. Create the two classes SolarBuilding and WindMill that both publicly inherit from Building. SolarBuilding has an instance variable that stores the energy generated by the solar panels. WindMill has an instance variable that stores the energy generated by the windmill. All member variables from classes must have getter and setter functions. Both classes should have the member variable(s) passed in and set in the constructor. Both classes must overridethe computerEnergyConsumption() function of the base class and use the instance variables in their computation. Use appropriate access modifiers in each class to enforce information hiding.

#include <iostream>
#include <iomanip>
using namespace std;

class Building
{
private:
    double energyConsumed;
public:
    virtual double computeEnergyConsumption() = 0;
    double getEnergyConsumed() { return this->energyConsumed; }
};

class SolarBuilding : public Building
{
private:
    double energyGenerated;
public:
    SolarBuilding(double energyGenerated)
    {
        this->energyGenerated = energyGenerated;
    }
    double getEnergyGenerated() { return this->energyGenerated; }
    void setEnergyGenerated(double energy) { this->energyGenerated = energy; }
    double computeEnergyConsumption() { return getEnergyGenerated(); }
};

class WindMill : public Building
{
private:
    double energyGenerated;
public:
    WindMill(double energyGenerated)
    {
        this->energyGenerated = energyGenerated;
    }
    double getEnergyGenerated() { return this->energyGenerated; }
    void setEnergyGenerated(double energy) { this->energyGenerated = energy; }
    double computeEnergyConsumption() { return getEnergyGenerated(); }
};

int main()
{
    SolarBuilding solarBuilding(3560.44);
    WindMill windMill(2500.00);

    cout << setprecision(2) << fixed;
    cout << endl << "Solar Panel [Energy consumed: " << solarBuilding.computeEnergyConsumption() << " units]";
    cout << endl << "Wind Mill [Energy consumed: " << windMill.computeEnergyConsumption() << " units]" << endl;
    return 0;
}
