pop_back()

template<typename _Tp, typename _Alloc = std::allocator<_Tp>>

void std::deque< _Tp, _Alloc >::pop_back ( )

inlinenoexcept

Removes last element.

This is a typical stack operation. It shrinks the deque by one.

Note that no data is returned, and if the last element's data is needed, it should be retrieved before pop_back() is called.
