    //Variable which want to write
    int data[]  = {65,66,67,68,69};
    //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 array in file
    fwrite(data, sizeof(data),1, fp);
    fclose(fp);
