C++ Program Using Encapsulation-Display Book Details & Compute Costs.

This is a sample program on encapsulation, Using encapsulation here we display the details of a book and compute costs.

#include <iostream.h>
#include <conio.h>
#include <stdio.h>

class book
{
    int bookno;
    float price;
    char booktitle[100];

    float total_cost(int n)
      {
         return (price*n);
      }

  public:

    void input()
      {
         cout<<"Enter Book Number, Price & Name Of Book";
         cin>>bookno>>price>>booktitle;
      }

    void purchase()
      {
         int n;
         cout<<"Enter Number Of Copies:";
         cin>>n;
         cout<<"Total Cost:"<<total_cost(n);

      }
};

void main()
{
    clrscr();
    book B;
    B.input();
    B.purchase();
    getch();
}

OUTPUT:

Enter Book Number, Price & Name Of Book
15422
