C++98: std::reverse()

std::reverse() reverses elements in a range. Strings have their own reverse() function. Here is an example:

#define _SCL_SECURE_NO_WARNINGS 1 // Turn off Microsoft Error/Warning

#include <algorithm>
#include <iostream>
#include <iterator>

int main()
{
  //            Index: 0  1  2  3  4  5  6  7
  int   sequence[8] = {1, 2, 3, 4, 5, 6, 7, 8};
  int * iter_beg    = &sequence[0];
  int * iter_end    = &sequence[8];

  std::reverse(iter_beg, iter_end);

  std::copy(&sequence[0]                             ,
            &sequence[8]                             ,
            std::ostream_iterator<int>(std::cout, " "));

  std::cout << std::endl;
  return 0;
}
// Output: 8 7 6 5 4 3 2 1
