    So how many different places did you cobble this together from?

    Code:
    Error E2268 assignment3.c 77: Call to undefined function 'display_an_account' in function main()
    Take a look at these error messages...
    Each one tells you a line number (77 in the example above), what the problem is, and which function it happens in...

    Just work through each one until you get them all fixed.

    Code:
     struct details
     {
         int number;
         char first_name[];
         char surname [];
         ADDRESS address;
         int age; 
         DATE DOB;
         int balance;
     };
    Give the array the number of elements.
    You don't want incomplete array here.

    Go through the errors one at a time starting at the first one.

    Error E2268 assignment3.c 77: Call to undefined function 'display_an_account' in function main()
    display_an_account is not prototyped. You may think it is, but a simple search will show you that it is not.
    Error E2108 assignment3.c 144: Improper use of typedef 'DETAILS' in function remove_an_account(details *)
    struct details needs sizes for the char array I think.
    Error E2227 assignment3.c 144: Extra parameter in call to search_database(details *) in function remove_an_account(details *)
    Pretty obvious. Prototype is: void search_database(DETAILS []) yet you define it and call it with two parameters.

    No we wouldn't know that... what we'd know is that we've helped you cheat on your final exam.

    Look, it's pretty simple... if you didn't bother to learn this in class, you should fail the test.

    Then you ALL deserve to fail, and he should be sacked.
    You would all be utterly useless in the workplace, so there's no point is there?

    Look at it this way, save yourself another year or two of going down the wrong road.

    Oh, and FWIW, read this
    A development process
    Dumping sorry messes of code on the forum for us to fix isn't going to work.

    Small steps, compiled often means you don't get swamped with errors.

    Another FWIW for the first error - learn how to spell.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    You might also notice a more than passing similarity to IrishFeeney's code... as well.

    here what is your problem.. im only starting in college and im sorry if im not stephen hawking .im new to doing programming.. the point of these boards are to get help and learn not listen to some inconsiderate person like yourself going on just cause your better doesnt mean you can moan on at other people
    DO YOU KNOW HOW TO READ?

    Each of the error messages you got has a line number and an explaination right in it.
    It's litterally telling you what's wrong with your code. All you need to do is Read and Fix...

    There is only one reason you can't do that... because you didn't write the code in the first place.
    If you had written it, you would know what's going on inside it and fixing errors would be childsplay.

    Then you are trying to fix the WRONG errors... you need to go, as a class, to the dean or principal and DEMAND a professor who actually knows what he's doing.

    No you should not fail because you have a bad teacher... but promoting you to the next year isn't the right answer either, since it's plain obvious you haven't learned the necessary materials...

    Therefore your only workable solution is to get a new teacher and get caught up on the stuff he didn't cover...

    And, btw, don't wait around for that to happen... there are a ton of books, e-books, tutorials and other courseware you can climb into and catch up... as I told feeney... sitting around waiting for people to spoon feed you information is a total fools errand.
