// This program will create a file, store data into it, and then print that
// data on the terminal

#include <stdio.h> // Include the standard C library for i/o
#include <stdlib.h> // Include the standard library for system calls and memory management

void main() {

    // Declare a character buffer, which will store the data to be written in the file
    char buffer[256];

    // Declare a FILE pointer
    FILE *fp;

    // Ask the user for the data to store
    printf("Please enter data to store in the file: \n");

    //write the data to the file
