I have just about completed my assignment for college - a simulation program
to show students how a stack, queue and linked list work.

There are a couple of errors on there - it compiles and runs fine - but it
would be great if another pair of eyes could scan it for me to see where it
is bombing out.

I hope someone can help - I need to get the documentation sorted soon

Many thanks

(a) You don't say what the errors are,
(b) You didn't post the section of code you're having trouble with, and
(c) You also didn't post a link to the code so we could see it.

So it's rather difficult to give you any specific help. However, I can
say:

It's almost certainly one or more bugs in your program.

I hope this was helpful to you...

You might also find it useful to add statements in strategic places to
log what is going on, values of important variables, etc.; stepping
through the code with the de{*word*81} will probably help; set breakpoints
in strategic locations.
