列出C ++，SQL和QT的重要主题 [英] List important topics for C++,SQL and QT

问题描述

下周我接受了关于C ++，QT和SQL的采访，任何人都可以给我一些关于C ++，QT和SQL的主题。

我几年没有接触过编程，所以失去了与编程的联系，也不知道C ++中的更新。



任何人都可以向我推荐一本好的书或网站，我可以提高我的知识。



提前感谢。

解决方案

你知道一周是非常短的时间。我几乎不相信你能为面试做好准备。但是：

C ++ 有一个新标准。如果你已经对语言有了很好的了解，我建议你只学习一些亮点，在我看来，这篇文章很适合：每个C ++开发人员应该使用的十大C ++ 11特性 [ ^ ]。另一方面，如果您不知道 C ++ ，您最好尝试理解该语言的基础知识。



我不知道 QT 所以我不能就这个论点向你提出任何建议。



如果您已经知道 SQL ，那么我想快速刷新您的知识就足够了。

另一方面，如果你没有' 有工作经验，是时候学习做一些练习。

就Qt而言，可能从下面开始，因为它支持了很多Qt开发：



信号和插槽 [ ^ ]

对象所有权和生命周期 [ ^ ]

活动 [ ^ ]



然而，Qt是巨大的，甚至上面的内容可能太多而无法覆盖1周。根据他们使用Qt的方式，可能会有关于网络的问题和 QML [ ^ ]，以及关于课程的具体问题。我发现在面试中说实话总是值得的，并说当你的知识存在差距，而不是回答一个你不知道答案的问题。


祝你好运！

I have an interview in next week on C++,QT and SQL can anyone give me imp topics of C++,QT and SQL.
I have not in touch with programming from couple of years, so lost touch with programming and also no idea about the updates in C++.

Can anyone suggest me a good book or sites where I can brush up my knowledge.

thanks in advance.

解决方案

You know a week is avery short time. I hardly believe you can properly prepare yourself for the interview. However:
C++ has a new standard. If you have already a good knowledge of the language I suggest you to learn just a few highlights, this article, in my opinion, is good for: Ten C++11 Features Every C++ Developer Should Use[^]. On the other hand if you don''t know C++, you better try to understand the basics of the language.

I don''t know QT so I can''t suggest you anything on this argument.

If you already know SQL, then I suppose a quick refresh of your knowledge would suffice.
On the other hand, if you haven''t a working experience with, it is time of studying an make a bit of practice.

In terms of Qt, probably start with the following as it underpins a lot of Qt development:

Signals and Slots[^]
Object Ownership and Lifetime[^]
Events[^]

However, Qt is huge and even the above may be too much to cover in 1 week. Depending on how they use Qt, there may be questions on networking and QML[^], as well as specific questions on classes. I''ve found it always pays to be honest in interviews and say when there is a gap in your knowledge, rather than answer a question you don''t know the answer to.

Good luck!
