Final Project

Task:

       We design a Library Management System but this time using File handling Technique.

(It creates a file and store the entered data in it,

we can also extract the data from any file using same technique)

Source code:

#include <iostream>

#include <conio.h>

#include <fstream>

#include<windows.h>

using namespace std ;

int main (  ) 

{

cout << " \n\n\t\t\t|--------------------| " << endl ;

cout << " \t\t\t|                    | " << endl ;

cout << " \t\t\t|       Library      | " << endl ;

cout << " \t\t\t|      Management    | " << endl ;

cout << " \t\t\t|       System       | " << endl ;

cout << " \t\t\t|                    | " << endl ;

cout << " \t\t\t|--------------------| " << endl ;

Sleep(3000); 

system("CLS");

string *books;

      int no,B_Pages,B_Price;

      string B_Name,A_Name,B_Edition;

ofstream file ( "data.txt",ios::app) ;

{

if ( file.is_open())

 {

 

           cout << " \n\n\t\tHow many books, you wants to enter " ;

cin >> no ;

books=new string[no];

for ( int i = 0 ; i < no ; i++ )

{  

           cout<<"\n\t::Enter the Following things of book #"<<i+1<<"::"; 

cout<<"\n\n\tEnter the Serial No. of book from 1--5::";

           cin>>books[i];

           file << " \n ____________________ " ;  

           file << " \n      *** New Book ***    \n " ;

cout<<"\nEnter the Name of book::";

           cin>>B_Name;

           file << "\nBook name:" ;

           file << B_Name;

           cout<<"\nEnter the Name of Author::";

           cin>>A_Name;

           file << "\nAuthor name:" ;

           file << A_Name;

           cout<<"\nEnter the Edition of book::";

           cin>>B_Edition;

           file << B_Price;

          }

getline(rfile,line) ;
