Only File handling and classes in library management system project code in c++. Can u plz help in the first evaluation of my project by telling be just the classes and file handling code in c++ of library management system. Give me the code of these without any errors.

The major three classes in the file handling are:

1) ifstream

Helps in reading the files

2) ofstream

Helps in writing the files

3) fstream

It helps in both reading and writing files.

Step-by-step explanation

Writing files:

#include <iostream>

// it includes the file stream classes from the library.

#include <fstream>

using namespace std;

int main() {

  // Create and open a text file

 ofstream file("filename.txt");

  // Write to the file

file << "Files can be tricky, but it is fun enough!";

// Closes the file stream

file.close();

}

Reading files:

#include <iostream>

// it includes the file stream classes from the library.

#include <fstream>

using namespace std;

int main() {

// Create a text string, which is used to output the text file

string str;

// Read from the text file

ifstream file("filename.txt");

while (getline ( file, str))

{

  // Print the read line to the context

  cout << str;

}

// Closes the file stream

file.close();

}
