    This is a part of a code i wrote, i BOLD-marked the problem,
    an anyone fine it?


    index = ((id%MAX_BORROW_SIZE)*(sizeof(
    brw_movie)));

    fseek(fp_borrowed, index, SEEK_SET);
    fread(&temp, sizeof(brw_movie), 1, fp_borrowed);

    if (temp.ordered == 1)
    {
    temp.ordered = 0;
    fseek(fp_borrowed, index, SEEK_SET);

    //temp.catalog_id = 0;
    fwrite(&temp, sizeof(brw_movie), 1, fp_borrowed);
    printf("Movie id# %d has been deleted from Borrowed Movies.\n", id);

    // **************** CHECK *************** //

    fseek(fp_borrowed, index, SEEK_SET);
    fread(&temp, sizeof(brw_movie), 1, fp_borrowed);
    printf(" --> %d\n", temp.ordered);



    OUTPUT -->

    What is the movie catalog no#? 22
    Your fine is: 75.000000 due to lag of 15 days!
    Movie id# 22 has been deleted from Borrowed Movies.
    --> 1
    The movie was already ordered by another customer (# 2).

    What happens if you comment out the line immediately before the bold printf?
