encapsulation c++ help

Question

Hi, can somebody correct my code?

#include <iostream>
using namespace std;

//class definition
class Car{

//private area
private:
int horsepowers;

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

//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;
}

THE ACTUAL PROBLEM:

You are a supercar engineer and currently setting the engine's horsepower.
Complete the given program by completing methods to set and get the horsepower of the car object in order to output it.
The program should warn "Too much" if the inputted horsepower is above 800.

Sample Input
950

Sample Output
Too much
950

DEFAULT CODE:

#include <iostream>
using namespace std;

//class definition
class Car{

//private area
private:
int horsepowers;

//public area
public:
//complete the setter function
void setHorsepowers() {

}

//complete the getter function
int getHorsepowers() {

}

};

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();

Answer 1

Setter function should be:
void setHorsepowers(horsepowers) {
this->horsepowers = horsepowers;
}

Getter function should be:
int getHorsepowers() {
return horsepowers;
}

In main function you should write if statement:
if (car.getHorsepowers() > 800) {
cout << "Too much" << endl;
}
cout << car.getHorsepowers() << endl;

Answer 2

Getter functions are used to return private attributes (horsepowers) inside the class (Car).So, you should just simply return horsepowers inside it.

int getHorsepowers(int h){
return horsepowers;}

The setter function is a void function . It doesn't return anything. You can print here whatever you want. So, you should print the warning and the value of horsepowers with a simple condition using if & else.

void setHorsepowers(){
if(h>800){

cout<<"Too much"<<endl; //this will always be printed whenever you call the setter function & the condition is met.
h=horsepowers;} // this is returned by getter function.

else{horsepowers=h;} //just return the value with no warning.

Remaining code remains the same.
