ForwardIt3 merge(ExecutionPolicy&&policy, ForwardIt1 first1, ForwardIt1 last1, ForwardIt2 first2, ForwardIt2 last2, ForwardIt3 d_first, Compare comp); (C++17 起) 归并二个已排序范围[first1, last1)和[first2, last2)到始于d_first的一个已排序范围中。
the first range of elements to merge first2, last2 - the second range of elements to merge d_first - the beginning of the destination range policy - the execution policy to use. See execution policy for details. comp - comparison function object (i.e. an object that satisfies the require...

suingstd::merge. Since that algorithm works only with iterators and only STL containers have iterators, one acceptable solution would be to save the files' contents into two STL containers and then merge the two usingstd::merge. Finally we can write the merged data back into a third text ...
