Passing global variables

New D.I.C Head Joined: 7 Jan, 2008 Posts: 1	I am trying to do an assignment where I declare at first 4 variables (actually they are linked lists), and try to pass them through 10 functions where only the last one actually uses them. Is there a way so that all my functions don't have to hold 4 parameters which they do not use, but they only pass? a kind of global variable accessed from anywhere (even if my functions are located in a header file)? I tried to declare them as global variables outside the main, and I tried to declare them on a separate namespace, but it still gives me errors Thank you for your time.

Any were in your application will be able to access them even when in different functions. Really what the assignment wants you to do is pass local variables declared in the main function to the rest of the functions. Each function then pass them onto the next and so on. You need to first declare 4 variables and just call the next function passing those variables to them. Also post your code up so we can help spot ur errors.
