    Sorting hand of cards in poker

    I am working on an assignment that involves creating a simplified poker game. I am new to C++, but this is for class, so I am here to learn. Anyways...

    After I deal each players hand vector, how would I sort the vector before it prints? They are char vectors called hand1 for player 1, and hand2 for player 2. The deck vector is a char as well, but the rank array is a string (so that the number 10 prints), and the suit array is a char (so that the actual symbols print). Instead of printing: 8<heart>, 3<club>, A<spade>, 4<spade>, 9 <diamond>, 8<club>, 2<club>, it would print: 2<club>, 3<club>, 4<spade>, 8<heart>, 8<club>, 9 <diamond>, A<spade>.

    I hope this was enough information. I can send my code if you'd like to look at it. No pointers, no classes. I'm not at that level yet (unless there is no other way to do what I am asking). I can improve upon this project in my next class.

    Sort it before you print?
    std::sort would work, but that would require iterators or pointers.

    How would I use sort with a vector? I have tried something similar with lists (which I have not ever used before this), but it definitely did not sort in any way.

    If you have a vector v, then

    std::sort(v.begin(), v.end());

    How exactly do you want the output to look like?

    I simply replaced your loop with

    std::sort(p1Hand.begin(), p1Hand.end());
    std::sort(p2Hand.begin(), p2Hand.end());

    to sort. But I don't know if the output is what you expect.

    Well over here you complain about how long you've been working on it, and how nice it would be to have as many people as possible to look at it.

    But if you're just going to delete the code as soon as only ONE person has read and replied to it, well -

    On the one hand, I normally revive posts deleted because "you got an answer".
    But somehow, I think it's more fitting that you should continue to suffer in silence knowing that no-one else can now contribute to your question.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    No - the OP can post it again themselves, if they're sincere about actually wanting some help.

    I wasn't thinking about the OP, but rather other people who would see this thread.
    That is why editing out or removing the code is a bad idea.

    This sounds like an interview question. I will add to it with how would you sort the deck making sure you touched every card and that the deck was fully shuffled in one pass?
