C++ Programing help: Write code to print out the Make, Model, and Year of the “crossOver1” variable.
Consider the below code. In this code, there are 4 classes (Automobile, Truck, Sedan, and CrossOverVehicle). The Automobile class is the based class of the Truck class and the Sedan class. The CrossOverVehicle inherits from both the Truck class and the Sedan class as its non-virtual base classes.
#include <iostream>
#include <string>
using namespace std;
// CLASS: Automobile
class Automobile
{
private:
string Make;
int Year;
string Model;
public:
string GetMake() { return Make; }
int GetYear() { return Year; }
string GetModel() { return Model; }
void SetMake(string value) { Make = value; }
void SetYear(int value) { Year = value; }
void SetModel(string value) { Model = value; }
public:
Automobile()
{
Make = "";
Model = "";
Year = 0;
cout << "Automobile default constructor is called." << endl;
}
Automobile(string make, string model, int year) :
Make(make),
Model(model),
Year(year)
{
cout << "Automobile constructor is called." << endl;
}
Automobile(const Automobile & src)
{
Make = src.Make;
Model = src.Model;
Year = src.Year;
cout << "Automobile copy-constructor is called." << endl;
}
public:
~Automobile()
{
cout << "Automobile destructor is called." << endl;
}
public:
const Automobile & operator=(const Automobile & src)
{
Make = src.Make;
Model = src.Model;
Year = src.Year;
cout << "Automobile assignment operator (=) is called." << endl;
return *this;
}
public:
static Automobile * CreateAutomobiles(int count)
{
return new Automobile[count];
}
};
// CLASS: Truck

}
public:
const Truck & operator=(const Truck & src)
{
Automobile::operator=(src);
cout << "Truck assignment operator (=) is called." << endl;
return *this;
}
};
// CLASS: Sedan
class Sedan : public Automobile
{
public:

}
public:
const Sedan & operator=(const Sedan & src)
{
Automobile::operator=(src);
cout << "Sedan assignment operator (=) is called." << endl;
return *this;
}
};
// CLASS: CrossOverVehicle
class CrossOverVehicle : public Truck, public Sedan
{
public:
CrossOverVehicle() :
Truck(),
Sedan()
{
cout << "CrossOverVehicle default constructor is called." << endl;
}
CrossOverVehicle(string make, string model, int year) :

int main()
{

// Provide code to print out the out the Make, Model, and Year of the “crossOver1” variable.
return 0;
