It would help if you described the error you're getting.

Line 14: customers is a std:queue of type <customerList>.
Line 81: names is a std::queue of type <int>
Line 82: customers.front() returns a value_type (which is a customerList). You then try to assign that to a queue<int> type. Those are different types. You can't assign one to the other.

The error message is quite clear. What are you trying to accomplish on line 82?
obscure (51)
It seems that he wants to iterate over the queue...

I wish to push front the customer generated numbers into the display.
LB (13399)
Then why did you use operator= instead of push()?

corrected. Thank you my friend.
