    That paragraph of supposed "facts" is nothing but opinion and poor assumptions based on insufficient data. The absolute LAST thing I would do is get into a freaking language war; its apples and oranges. Like I said, if you don't like it, go program in C.

    I can write a "permutation program" in less than five minutes using C++.

    These functions exist in the standard library:

    prev_permutation
    next_permutation



    I also dare say that they're pretty fast.

    Maybe if you want to use strcat() you can do this:
    if you have x, y, w as strings, and you want to put x and y in w.
    Code:
    strcat(w,y);
    strcat(w,x);
    or you can change the order but I think it will do the jub

    sangdrax, you sure those are iso standard? Well, guess that doesn't matter. Not bad for c++.

    Yeah, eibro, i'll go program in C. I wouldn't post this, except that you say i'm putting those forth as "Facts". Never said that. Put that forward as my opinion, and at this moment in time I stand by it.

    Yes. This is a quote from the ISO/IEC standard specification:

    25.3.9 Permutation generators
    Code:
    template<class BidirectionalIterator>
    bool next_permutation(BidirectionalIterator first,
    BidirectionalIterator last);
    template<class BidirectionalIterator, class Compare>
    bool next_permutation(BidirectionalIterator first,
    BidirectionalIterator last, Compare comp);
    1 Effects:
    [...]
    Code:
    template<class BidirectionalIterator>
    bool prev_permutation(BidirectionalIterator first,
    BidirectionalIterator last);
    template<class BidirectionalIterator, class Compare>
    bool prev_permutation(BidirectionalIterator first,
    BidirectionalIterator last, Compare comp);
    3 Effects:
