Hello everyone,


Just a basic question which I could not find answer from MSDN
currently, for frequently used member functions for queue class, there
is,

1. push;
2. pop;
3. back;
4. front.

I know (1) will throw exception, for example, out of memory. How about
(2), (3) and (4)? Will they be possible to throw any exceptions and in
what situations if there are exceptions? From MSDN declaration of
exception specification for the functions, I can not find the answer.


thanks in advance,
George
