std::list fixed size

Question

How can I create std::list with a fixed element count?

Answer 1

#include <list>

// list with 5 elements, using default constructor
const size_t fixedListSize(5);
std::list<int> mylist(fixedListSize);  

If you want it to always have exactly 5 elements you'd have to wrap it in a facade class to prevent insertion and erasure.

If that is indeed what you want, you'd be better off using a different container instead of list, since as noted in other responses you would be hiding the most advantageous features of list.
