Why am I getting "invalid conversion from 'Queue*/Stack*' to 'int'" error message?

Why am I getting the errors invalid conversion from 'Queue*' to 'int' & conversion from 'Stack*' to non-scalar type 'Stack' requested?

I've tried modifying Queue & Stack but to no avail. I am doing an assignment that Implements Stack using Queues & Implements Queue using Stacks.
