| iterator insert( const value_type& value ); | (1) | |
| iterator insert( value_type&& value ); | (2) | (since C++11) | 
| iterator insert( iterator hint, const value_type& value ); iterator insert( const_iterator hint, const value_type& value ); | (3) | (until C++11) (since C++11) |

Inserts element(s) into the container.
1-2) inserts value. If the container has elements with equivalent key, inserts at the upper bound of that range.(since C++11)
3-4) inserts value in the position as close as possible, just prior(since C++11), to hint.
5) inserts elements from range [first, last).
6) inserts elements from initializer list ilist.
No iterators or references are invalidated.

[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 | 
| Type requirements | ||
| - InputItmust meet the requirements ofInputIterator. | ||
[edit] Return value
1-2) returns an iterator to the inserted element.
3-4) returns an iterator to the inserted element.
5-6) none.
[edit] Complexity
1-2) Logarithmic in the size of the container, O(log(size())).
3-4) Amortized constant if the insertion happens in the position just after(until C++11)/before(since C++11) the hint, logarithmic in the size of the container otherwise.
5-6) O(N*log(size() + N)), where N is the number of elements to insert.
