Inserts elements to the container.

1-2) inserts value.

3-4) inserts value, using hint as a suggestion where the element should go.

5) inserts elements from range [first, last).

6) inserts elements from initializer list ilist.

[edit] Parameters

hint	-	iterator, used as a suggestion as to where to insert the content
value	-	element value to insert
first, last	-	range of elements to insert
ilist	-	initializer list to insert the values from

[edit] Return value

1-2) returns a pair consisting of a bool denoting whether the insertion took place and an iterator to the inserted element.

3-4) returns an iterator to the inserted element or to the element, that prevented the insertion.

5-6) none.
