iter_swap(3C++)			       -		       iter_swap(3C++)

Standard C++ Library Copyright 1998, Rogue Wave Software, Inc.

NAME
       iter_swap

	- Exchanges values in two locations.

SYNOPSIS
       #include <algorithm>
       template <class ForwardIterator1, class ForwardIterator2>
       void iter_swap (ForwardIterator1, ForwardIterator2);

DESCRIPTION
       The  iter_swap  algorithm  exchanges  the  values pointed to by the two
       iterators a and b.

EXAMPLE
       #include <vector>
       #include <algorithm>
       #include <iostream>
       using namespace std;

       int main ()
 {
  int d1[] = {6, 7, 8, 9, 10, 1, 2, 3, 4, 5};
   //
   // Set up a vector.
   //
  vector<int> v(d1+0, d1+10);
   //
   // Output original vector.
   //
  cout << "For the vector: ";
  copy(v.begin(), v.end(),
       ostream_iterator<int,char>(cout," "));
   //
   // Swap the first five elements with the
   // last five elements.
   //
  swap_ranges(v.begin(), v.begin()+5, v.begin()+5);
   //
   // Output result.
   //
  cout << endl << endl
  << "Swapping the first 5 elements with the last 5 gives: "
	<< endl << "	 ";
  copy(v.begin(), v.end(),
       ostream_iterator<int,char>(cout," "));
   //
   // Now an example of iter_swap -- swap first and
   // last elements.
   //
   iter_swap(v.begin(), v.end()-1);
   //
   // Output result.
   //
  cout << endl << endl
	<< "Swapping the first and last elements gives: "
	<< endl << "	 ";
  copy(v.begin(), v.end(),
       ostream_iterator<int,char>(cout," "));
  cout << endl;

  return 0;
 }

Program Output

For the vector: 6 7 8 9 10 1 2 3 4 5
Swapping the first five elements with the last five gives:
    1 2 3 4 5 6 7 8 9 10
Swapping the first and last elements gives:
    10 2 3 4 5 6 7 8 9 1

WARNINGS
       If your compiler does not support default template parameters, then you
       always  need  to	 supply the Allocator template argument. For instance,
       you have to write:

       vector<int, allocator<int> >

       instead of:

       vector<int>

       If your compiler does not support namespaces, then you do not need  the
       using declaration for std.
