## Function replace_nth_copy

boost::algorithm::replace_nth_copy — Replace nth algorithm.

## Synopsis

    template<typename OutputIteratorT, typename Range1T, typename Range2T,
             typename Range3T>
      OutputIteratorT
      replace_nth_copy(OutputIteratorT Output, const Range1T & Input,
                       const Range2T & Search, unsigned int Nth,
                       const Range3T & Format);
    template<typename SequenceT, typename Range1T, typename Range2T>
      SequenceT replace_nth_copy(const SequenceT & Input, const Range1T & Search,
                                 unsigned int Nth, const Range2T & Format);

## Description

Replace an Nth (zero-indexed) match of the search string in the input with the format string. The result is a modified copy of the input. It is returned as a sequence or copied to the output iterator.

Parameters

Format

  A substitute string

Input

  An input string

Nth

  An index of the match to be replaced. The index is 0-based.

Output

  An output iterator to which the result will be copied

Search

  A substring to be searched for

Returns: An output iterator pointing just after the last inserted character or a modified copy of the input
Notes: The second variant of this function provides the strong exception-safety guarantee
