Inserts elements at specified position in the container.
1-2) inserts
value
before the element pointed to by pos
3) inserts
count
copies of the value
before the element pointed to by pos
4) inserts elements from range
[first, last)
before the element pointed to by pos
. The behavior is undefined if first
and last
are iterators into *this.
5) inserts elements from initializer list
ilist
.No iterators or references are invalidated.

[edit] Parameters
pos | - | element before which the content will be inserted |
value | - | element value to insert |
first, last | - | the range of elements to insert, can't be iterators into container for which insert is called |
ilist | - | initializer list to insert the values from |
Type requirements | ||
-
InputIt must meet the requirements of InputIterator .

[edit] Return value
1-2) iterator pointing to the inserted value
3) iterator pointing to the first element inserted, or pos
if count==0.
4) iterator pointing to the first element inserted, or pos
if first==last.
5) iterator pointing to the first element inserted, or pos
if ilist
is empty.
[edit] Complexity
1-2) Constant.
3) Linear in count
4) Linear in std::distance(first, last)
5) Linear in ilist.size()
