umm, sorry if it was not understandable, i tried to come up with a very long name for a type i want to define... so i made the name myself, don't try it it won't work. unless you define such a class....

Depending on the spacing...(if it doesn't matter) you can use a LIFO stack... I'd use the STL stack...the code would look like this:
#include <iostream>
#include <string>
#include <stack>

using...
