你有没有问过你的导师要澄清一下吗？

好吧，它看起来非常简单。尝试在教科书中查找聚合
。关于这个问题的思考 - 从一张卡开始，然后
想到一个甲板，这应该让你感动。
我唯一不喜欢的东西要理解的是，一张完整的牌照可以拥有所有56张牌。

1.你对你理解的部分的具体了解更多
，你的问题是什么，你得到的帮助就越大。
2.我认为首先教授方法是不好的想法
是现实生活中真正的C ++程序员的首选。所以，在创建你自己的动态操作数组之前，你应该
熟悉std :: vector并且总是使用它，除非它不合适
由于某种原因。同样地使用std :: random_shuffle进行所有
改组，除非由于某种原因它不合适。
3.做什么：写一些代码。不要尝试在
做一切，但是在每一步之后进行编译和测试。如果您的代码没有工作，请记得在询问
问题时在此处发布相关的摘录。 Marshall Cline的C ++ FAQ中介绍了这个问题。在发布之前检查常见问题解答总是好的。
总是很好。您可以在以下网址获取常见问题解答

4.你的教练显然有一个关于
& ;聚合" ;.您可能只是礼貌地忽略它并且
使用以普通方式包含其他类的类。
I have been given a list of exercises to do by my tutor, one of which is
this:

Which i am finding very difficult to understand what is required and how
exactly to do it.. Any thoughts/idea''s will be greatfully recieved!

Have you asked your tutor for some clarification?

Well, it looks pretty straightforward. Try looking up "aggregation"
in your textbook. Ponder on the problem -- start with a Card, then
think of a Deck, this should get you moving.
The only thing that I don''t comprehend is how a full deck of
cards can have "all the 56 cards".

1. The more specific you are about what part you _do_ understand
and what your questions are, the better the help you will get.
2. I think it''s a bad idea to teach methods first that would not be
the first choice of a real C++ programmer in real life. So, before
creating your own dynamically manipulated array, you should be
familiar with std::vector and use it always unless it is unsuitable
for some reason. Likewise use std::random_shuffle for all your
shuffling unless it is unsuitable for some reason.
3. What to do: write some code. Don''t try to do everything at
once, but compile and test after each step. If your code doesn''t
work, remember to post relevant excerpts of it here when asking
questions. This issue is covered in Marshall Cline''s C++ FAQ. It
is always good to check the FAQ before posting. You can get the FAQ
at: http://www.parashift.com/c++-faq-lite/
4. Your instructor apparently has a tic about the word
"aggregation". You should probably just politely ignore that and
use classes that contain other classes in the ordinary manner.
