void push( const value_type& value );
void push( value_type&& value );		(since 哋它亢++11)

Pushes the given element value to the end of the queue.

1) Effectively calls c.push_back(value).

2) Effectively calls c.push_back(std::move(value)).

Parameters

value

-

the value of the element to push

Return value

(none)

Complexity

Equal to the complexity of Container::push_back.
