c++ - STL containers element destruction order

Question

Does ISO C++ standard mandate any sort of destruction order of objects inside STL containers?

• Are std::list/std::vector/std::map elements destroyed starting from the beginning or the end of the container?
• Can I rely on std::map storing its elements in std::pairs internally so a key in a pair is destroyed before its value (or vice versa)?

Answer 1

1. Unspecified in the standard.
2. Yes, but this means that the key is destroyed after its associated value.
