#key# EOF: indicates "end of file" #key# is a special delimiter or data that is placed at the end of a file after the last byte of data in the file.

The purpose of this delimiter is to indicate the end of file to file-reading programs. This is also useful for the storage and transmission of data.



# Code
## 1. EOF file in C++
The following code detects the EOF in C++. It reads and displays each character in the file until it reaches the end of file delimiter. Once EOF is detected, it outputs it as well.

#include <iostream>  
#include <fstream>      

int main () {

  std::ifstream is("myfile.txt");   // open file

  char c;
  while (is.get(c)) 
    std::cout << c;

  if (is.eof())  
    std::cout << "[EoF reached]\n";
  else
    std::cout << "[error reading]\n";

  is.close();

  return 0;
}

## 2. EOF file in Python
The following code detects the EOF in Python. It reads and displays each character in the file until it reaches the end of file delimiter. Once EOF is detected, it outputs it as well.

f = open("myfile.txt", "r")
while True:
    line = f.readline()
    if not line:
        print("EoF reached")
        break
    print(line)

What is EOF?

EOF indicates the end of a file in programming, signaling file-reading programs when to stop processing data.
