#include <stdio.h>
typedef struct
{
    int id;
    char fName[16];
    char lName[16];
} s_employee;
int main()
{
    //Populate structure variable
    s_employee sAmlendraInfor =  {8886, "Amlendra", "Mishra"};
    //file pointer
    FILE *fp = NULL;
    //create and open the text file
    fp = fopen("aticleworld.dat", "wb");
    if(fp == NULL)
    {
        printf("Error in creating the file\n");
        exit(1);
    }
    //write the structure in file
