 #include<iostream>  
 #include<string>  
 using namespace std;  
 class wheel  
 {  
   private:  
   string name_of_compnay;  
 public:  
 void GetCompany()

 }  
 void print()  
 {  
   cout<<"Wheel compny is "<<name_of_compnay<<endl;  
 }  
 };  
 class car   
 {  
   private:  
     int Number_of_wheel;  
     wheel objWheel;//object of wheel class inside car(Assocation) relationship between class .  
   public:  
     int GetNumbeOfWheel()  
     {  
       cout<<"How many wheel has problem in your car :";  
       cin>>Number_of_wheel;  
        objWheel.GetCompany();  
     }  
     void print_car()  
     {  
       objWheel.print();  
       cout<<"You can change :"<<Number_of_wheel<<endl;  
     }  
 };  
 int main()  
 {
