#include <iostream>

class Book {
 public:
   string BkName;
   int BkId;
   string BkAuthor;
  /* Book (string x, int y, string z){
   BkName = x;
   BkId = y;
   BkAuthor = z;
   }
   */
   void BKUpdateDetails()
   {
   cout<<"Enter Book Name: "; cin>>BkName;
   cout<<"Enter Book ID: "; cin>>BkId;
   cout<<"Enter Book Author: "; cin>>BkAuthor;
   }
   void BKDisplay()
   {
   cout<<"BookName"<<" "<<"BookId"<<" "<<"BookAuthor"<<endl;
   cout<<BkName<<" "<<BkId<<" "<<BkAuthor<<endl;
   }
};

int main()
{
    class Book b;
    b.BKUpdateDetails();
    b.BKDisplay();
    cin.get();
    return 0;
}
