    You seem to be very fond of using floating point variables...

    I know this won't actually solve the "real" problem, but surely an employee id is not a double? If they are, who is employe id 3.1415926...?

    	double a, b,d,e,f,g;
    	cout<<"1. Add an employee"<<endl;
    	cout<<"2. Modify employee data"<<endl;
    	cout<<"3. Delete an employee"<<endl;
    	cout<<"4. Exit this menu"<<endl;
    Are you planning on having options 1.2, 1.3, 1.8 and 2.5 as well? Otherwise either an integer or a char will do fine here (int will be less changes to the code below).

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    What syntax? Syntax for what?

    Outside of your DOS world, your header file is meaningless.

    I still don't know what to do. How should I change my code to to make it work?

    Write out your Employee class, keep it simple.

    Write the program that you were supposed to test it with as homework.

    Then write the other menu driven program. If it were me in your shoes, I would just shove Employee into a std::vector (look it up on the internet) and get the options working.

    I really don't know where a multidimensional array fits in, sorry. You'll have to ask your professor about it. I'm assuming that the multidimensional array is optional as a suggestion, and not something your professor wants you to do.

    What does your latest code look like?
    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.
