constexpr void resize(size_type sz);

1

#

Preconditions: T is Cpp17DefaultInsertable into list.

2

#

Effects: If size() < sz, appends sz - size() default-inserted elements to the sequence.

If sz <= size(), equivalent to:list::iterator it = begin(); advance(it, sz); erase(it, end());

constexpr void resize(size_type sz, const T& c);

3

#

Preconditions: T is Cpp17CopyInsertable into list.

4

#

Effects: As if by:if (sz > size()) insert(end(), sz-size(), c);else if (sz < size()) { iterator i = begin(); advance(i, sz); erase(i, end());}else ; // do nothing
