Subject: Nice combination algorithms=0D

I have been learning C++ for some time and here are 2 nice standard libra=
ry=20
algorithms for combinations. next_permutation() and =0D
=0D
=3D=3D>prev_permutation() defined in <algorithm>. Reference: TC++PL 3 on =

545, 18.10).=0D

And since they are generic they can be used with whatever kind of objects=
 (e
g. .NET objects). An example:=0D

#include <iostream>=0D
#include <string>=0D
#include <algorithm>=0D
 =0D
int main()=0D
{=0D
 using namespace std;=0D
 =0D
 string s=3D"abcd";=0D
 =0D
 do=0D
   cout<<s<<endl;=0D
 while(next_permutation(s.begin(), s.end()));=0D
