Any Garbage value in STL stack in c++?

Question

stack<int> s;
while(!s.empty()) s.pop;

I saw this in a book before using a STL stack. this means if the stack holds any value this will be popped out. but when I used a stack.I saw it don't hold any value after declaration. Is there any possibility to hold any garbage value after declaration of STL stack?

To simply answer your question, basically once you declare a stack it is not initialized with garbage values. (It is good practice to initialize stuff in general though)
