Change the number of elements stored.
void resize( std::size_t count);
Resizes the container to contain count
elements. If capacity() < size() + count,
a reallocation occurs first, and all iterators and references are invalidated.
Any past-the-end iterators are always invalidated.
size()
> count,
the container is reduced to its first count
elements.
size()
< count,
additional null values are appended.
Linear in abs(size() - count), plus the cost of reallocation if capacity() is less than count.
Strong guarantee. Calls to memory_resource::allocate
may throw.
