    how can i update a record????

    I was wondering if it is possible to display a record in a linked list, or any other structure and be able to update the record rather than delete the record an re-enter it

    any help would be awesome

    Well once it's in memory, you can do what you want with it

    Easiest thing to do is to visualise what is going on by drawing 'before' and 'after' pictures of your data structure (eg. array), and the action (eg. add) which you want to perform.

    Code:
    record[i] = update( record[i] );
    Update displays all the fields of a record, prompts for changes, then returns the updated copy when all is done. The assignment then updates your record.

    Or something else?
