Answer 2

#include <iostream>
using namespace std;

//class definition
class Car{

//private area
private:
int horsepowers;

//public area
public:
//complete the setter function
void setHorsepowers(int x){
horsepowers = x;
if (x >800){
cout << "Too much" << endl;
}
}
//complete the getter function
int getHorsepowers() {
return horsepowers;
}

};

int main() {
//getting input
int horsepowers;
cin >> horsepowers;
//creating the object of class Car
Car car;
//setting the value for private member
car.setHorsepowers(horsepowers);
//printing the value of private member
cout << car.getHorsepowers();

return 0;
}

#include <iostream>

}
}
//complete the getter function
int getHorsepowers() {
return horsepowers;
}

};

int main() {
//getting input
int horsepowers;
cin >> horsepowers;
//creating the object of class Car
Car car;
//setting the value for private member
car.setHorsepowers(horsepowers);
//printing the value of private member
cout << car.getHorsepowers();

return 0;
}

Good Luck

Answer 4

I slightly edited this code there were some mistakes but I solved them, so I think this is the solution.

public:
//complete the setter function
void setHorsepowers(int x){
horsepowers = x;
}

//printing the value of private member
if (car.getHorsepowers() >800) cout << "Too much" << endl;
cout << car.getHorsepowers();
