It scans arguments the same as normal token processing, but instead of placing output tokens in the main preprocessor output, it builds a replacement token list for each of T ’s arguments.
WebFor both overloads, if the iterator type is mutable, f may modify the elements of the range through the dereferenced iterator. If f returns a result, the result is ignored. If n is less than zero, the behavior is undefined.. Unlike the rest of the parallel algorithms, for_each_n is not allowed to make copies of the elements in the sequence even if they are trivially copyable.
