Defined in header <iterator>
template< class Container > std::back_insert_iterator<Container> back_inserter( Container& c );

back_inserter is a convenience function template that constructs a std::back_insert_iterator for the container c with the type deduced from the type of the argument.

Parameters

c

-

container that supports a push_back operation

Return value

A std::back_insert_iterator which can be used to add elements to the end of the container c

Possible implementation

template< class Container > std::back_insert_iterator<Container> back_inserter( Container& c ) { return std::back_insert_iterator<Container>(c); }
