Construct a back insert iterator
This function generates a back insert iterator for a container.
A back insert iterator is a special type of output iterator specifically designed to allow algorithms that usually overwrite elements (such as copy) to instead insert new elements at the end of the container.
Parameters
- x
- Container for which the back insert iterator is constructed.
Return value
A back_insert_iterator that inserts elements at the end of container x.
