Removes the last element of the container.

Ifempty() istrue:

• If the implementation ishardened, acontract violation occurs. Moreover, if the contract-violation handler returns under “observe” evaluation semantic, the behavior is undefined.
• If the implementation is not hardened, the behavior is undefined.

Iterators and references to the last element are invalidated. Theend() iterator is also invalidated.
