resize() [3/3]

void resize	(	std::size_t	new_size,
		do_not_initialize_t
	)

Changes the size of the vector without initializing memory allocated for any new elements, if there are any. .

Parameters

new_size

The desired size of the vector. If the value is less than the current size of the vector, the excessive elements are removed from the end of the vector. If the value is greater than the current vector size, new memory is allocated, as required, but the elements themselves are left uninitialized.

Warning

The caller is responsible for construction of the elements in place of the respective memory locations prior to any operations upon vector and/or its elements that might involve assignment, access or destruction of the new elements.
