Question

Create a class called planet with private members name, percent02, temp. Create a constructor prototype and implementation. In the main, create 2 objects of class planet, one with arguments and the other without. Create a function to change name, percent02 and temp after the object has been created and a function that displays the current values of the members. Implement the operations specified above in the main of your program. This is all in C++, please help.

Please find the code below:::::

#include <iostream>
#include <string>
using namespace std;
class Planet{
private:
   string name;
   float percentO2;
   int temp;
public:
   Planet(){
       name="";
       percentO2 = 0;
       temp = 0;
   }

   Planet(string n,float p,int t){
       name=n;
       percentO2 = p;
       temp = t;
   }

   string getName() const
   {
       return name;
   }

   float getPercentO2() const
   {
       return percentO2;
   }

   int getTemp() const
   {
       return temp;
   }

   void setName(string name)
   {
       this->name = name;
   }

   void setPercentO2(float percentO2)
   {
       this->percentO2 = percentO2;
   }

   void setTemp(int temp)
   {
       this->temp = temp;
   }

   void display(){
       cout<<"Name of the Planet : "<<name<<endl;
       cout<<"Percent of O2 of the Planet : "<<percentO2<<endl;
       cout<<"Temperature of the Planet : "<<temp<<endl;

   }

};

int main(){
   Planet p;
   Planet p2("Earth",68.32,24);
   cout<<"Printing Planet p : "<<endl;
   p.display();
   cout<<endl;
   cout<<"Printing Planet p2 : "<<endl;
   p2.display();

   cout<<"\nSetting value to Planet P"<<endl;
   p.setPercentO2(99.99);
   p.setName("Mars");
   p.setTemp(120);
   p.display();

   return 0;
}
