If you have enough time try to write an application using C++ - go over the basics so when you'll be asked to show coding skills you'll be able to write code fluently.

I've noticed that during C++ centric interviews it is common practice to ask question about how it works:

<ul>
<li>How virtual methods are implemented?</li>
<li>What happens when you call <code>new</code> - how memory is allocated?</li>
<li>What is the difference between struct and class?</li>
<li>Why should you mark your class d'tor as virtual?</li>
</ul>

I guess a good way to learn all those is to read a good C++ book - if you have the stomach for it you can read <a href="http://www.research.att.com/~bs/3rd.html" rel="noreferrer">Stroustrup book</a> - but there bound to be other books just as good (with less pages in them).

Have a look at the <a href="http://www2.research.att.com/~bs/bs_faq2.html" rel="noreferrer">C++ Style and Technique FAQ</a>

blocks|key|822636|text|作为一个应聘者，我依赖于经验。作为一名面试官，我最喜欢(通常也是唯一的)+C%2B%2B面试问题是“告诉我关于复制构造器的信息”。令人惊讶的是，这打开了许多途径，而且很少有人意识到这些途径--这可以使面试变得非常简短。如果受访者回答了这个问题，我就会问：“你最喜欢的C%2B%2B书籍有哪些?为什么？”|type|unstyled|depth|inlineStyleRanges|entityRanges|data|822637|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

As an interviewee, I depend on experience. As an interviewer, my favourite (and often only) C++ interview question is "Tell me about the copy constructor". It's amazing how many avenues this opens up, and how few people are aware of them - it can make for a very short interview. If the interviewee gets past that, I then ask "Which are your favourite C++ books, and why?"

blocks|key|75217|text|懂这门语言。你可以试着预测他们会问什么问题，但是C%2B%2B可能意味着很多不同的事情，这取决于你问的是谁。对一些人来说，它是一个笨拙的Java，所有的问题都是关于动态内存分配、虚函数和继承。对于其他人来说，这一切都是关于RAII的，并避免了内存管理。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|75218|有些人认为STL是最重要的问题，有些人可能想深入了解该语言的一些更微妙的方面(从Neil在他的回答中提到的复制构造函数，到未定义行为的常见情况，或者异常安全)|75219|它是一门庞大而复杂的语言，人们可以对它提出很多不同的问题。除非你知道他们可能会关注哪些领域，否则你不太可能在最后一刻温习功课。|75220|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Know the language. You can try to predict what questions they'll ask, but C++ can mean a lot of different things depending on who you ask. To some people, it's a clumsier Java, and all the questions will be about dynamic memory allocation, virtual functions and inheritance. To others, it's all about RAII, and avoiding memory management.

Some think the STL is the most important to ask questions about and some might want to dig in to your knowledge of some of the subtler aspects of the language (ranging from the copy constructor that Neil mentioned in his answer, to common cases of undefined behavior, or exception safety)

It's a big, complex language, and people can ask a lot of different questions about it. Unless you have some idea what areas they're likely to focus on, you're not likely to achieve much with last-minute brushing up.

It depends: I went for a job with a certain large games company and 90% of the questions were graphics and micro-optimisation questions (this was for a C# testing role, stupidest test of my life!).

However, if you're going for a normal desktop-app role, you'll probably get asked about UIs, or if you're going for some sort of embedded computing role you'll likely be asked about optimisation and memory management.

In any case, I'd brush up on your BOOST, as an example of a good library, and your pointer knowledge.

blocks|key|821453|text|我只想回顾一下这门语言的基础知识:确保你记得如何创建类，知道什么时候通过引用传递它，什么时候通过指针传递，以及为什么你想要这样做而不是通过值传递。为什么你想要一个虚方法，当你需要一个复制构造函数时，使用C%2B%2B风格的转换而不是C风格的转换的原因是什么，诸如此类|type|unstyled|depth|inlineStyleRanges|entityRanges|data|821454|我可以想象，记住一两个关于C%2B%2B的战争故事会有帮助：(“天哪，常量的正确性很难！”，“所以我曾经和一个同事/老师就C%2B%2B的这个细节发生了争执，我学到了这一点……”|821455|如果这是一份入门级的C%2B%2B工作(应该是你有限的C%2B%2B经验)，我想这会很好，而且如果没有一位划桨/高级工程师来指导你，你不会(希望)被投得太深。|821456|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

I would just review the basics of the language: make sure you remember how to make classes, know when to pass it via reference and when to pass in via pointer, and why you'd want to do that vs pass by value. Why you'd want a virtual method, and what are the reasons one uses the C++ style casts vs the C style casts, when you'll need a copy constructor, things like that

I'd imagine what would help is remembering a war story or two about C++: ("man, const correctness is hard!", "so I once got into a fight with a coworker/teacher about this finer point of C++, and I learned that.."

If the job is for an entry level C++ job (which it should be with your limited C++ experience), I'd imagine that would be fine and that you'll (hopefully) not get cast too deep without a paddle/senior engineer to guide you.

"write a function that counts the number of 'on' bits in a byte"

that never gets old...

I saw a cool bitwise way of doing it once that could count all the on bits in a 32 bit DWORD in like 4 or 5 operations!
