Yeah, I got bit by the same bug. The university tended to lean on Java, and then allowed you to choose the language you wanted to work with during projects.

The best way is to just jump in. Start small, take baby steps, and just Google things that confuse you when you get there. Also find projects that have released their source code. See how they structure their programs. Basically, just tinker with concepts. There is plenty of information around the web.

Make it fun and grab a <a href="https://rads.stackoverflow.com/amzn/click/com/1598633600" rel="noreferrer" rel="nofollow noreferrer">C++ game development book</a> so it doesn't become mind numbing too quickly.

blocks|key|704215|text|如果你已经了解Java/C#，我建议你直接使用C而不是C%2B%2B。根据该网站的说法，GLUT具有与C%2B%2B相同的C绑定，因此您应该已经准备好了。无论如何，学习C的最好方法是购买并阅读一份“C编程语言”，然后坐下来与C编译器一起运行你的东西。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|704216|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|$]]

If you already know Java/C# I'd recommend going directly to C instead of C++. According to the website, GLUT has the same bindings for C as C++ so you should be all set. Anyways, the best way to learn C is to purchase and read a copy of "The C Programming Language" and sit down with your C compiler and get your stuff to run.

I love this book in all 3 editions, and it was one of the books in a class I had as a Senior at UT, but it's just not a starting book. You can become comfortable in C++ with a lot less, though you certainly won't be one with the compiler until you have read Meyer's work. 

I don't know if it's still in print but I found Navigating C++ usefull, but I was also very comfortable with pointers from Pascal. Err of course I am forgetting that 15 years ago you had to learn what OOP was, now it's a little more assumed. So perhaps Meyer's is not out of line. Thoughts?

blocks|key|5158942|text|主要有两点不同:语法和内存管理。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5158943|在C%2B%2B中有指针，它是更强大(或更弱，取决于您对power的解释)的对象引用，这是您从Java中已经知道的。|5158944|在Java中，您可以这样做：|5158945|Thing+mything+=+new+Thing();+//+mything+is+an+object+reference
mything.method();|code-block|syntax|javascript|5158946|在C%2B%2B中，您将执行以下操作：|5158947|Thing+*+mything+=+new+Thing();+//+mything+is+an+object+pointer
mything->method();
delete+mything;|5158948|句法上的区别很明显：'->‘而不是'.’。当从指向对象的指针调用对象方法时。在C%2B%2B中，当你处理完一个对象时，你必须显式地释放内存。归根结底，在C%2B%2B和Java中，您正在做同样的事情:实例化对象和调用方法，在每一行的末尾放置无用的分号，等等。|5158949|mything+=+Thing()+#+mything+is+whatever+I+want+it+to+be
mything.method()|5158950|浏览任何不太像样的C%2B%2B文本将帮助您填写其余的细节。|5158951|entityMap^0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|W|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|X|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|Y|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|Z|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|10|8|@]|9|@]|A|$]]|$1|M|3|N|5|H|7|11|8|@]|9|@]|A|$I|J]]|$1|O|3|P|5|6|7|12|8|@]|9|@]|A|$]]|$1|Q|3|R|5|H|7|13|8|@]|9|@]|A|$I|J]]|$1|S|3|T|5|6|7|14|8|@]|9|@]|A|$]]|$1|U|3|-4|5|6|7|15|8|@]|9|@]|A|$]]]|V|$]]

There are two main differences: the syntax, and memory management.

In C++ you have pointers, which are more powerful (or less powerful depending on your interpretation of power) object references, which you already know about from Java.

In Java you might do this:

<pre><code>Thing mything = new Thing(); // mything is an object reference
mything.method();
</code></pre>

In C++ you would do this:

<pre><code>Thing * mything = new Thing(); // mything is an object pointer
mything-&gt;method();
delete mything;
</code></pre>

The syntactical difference is obvious: '->' instead of '.' when calling an object method from a pointer to an object. In C++, you have to free the memory explicitly when you are done with an object. At the end of the day you are doing the same thing in C++ and Java, instantiating objects and calling methods, putting useless semicolons at the end of every line, etc. Is it any wonder that Python is becoming so popular?:

<pre><code>mything = Thing() # mything is whatever I want it to be
mything.method()
</code></pre>

Skimming through any half decent C++ text will help you fill in the rest of the details.

blocks|key|2903830|text|我也非常推荐Bruce+Eckel的Thinking+in+C%2B%2B。对于想要进入C%2B%2B思维模式的有经验的程序员来说，这是一本很棒的书。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2903831|他很好心，把他的书制作成了电子版的available+for+free。|2903832|entityMap|0|LINK|mutability|MUTABLE|url|http://mindview.net/Books/TICPP/ThinkingInCPP2e.html|1|http://mindview.net/Books/DownloadSites/^0|I|F|0|0|H|I|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@$A|Q|B|R|1|S]]|C|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|F|3|-4|5|6|7|X|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]]]

I also thoroughly recommend Bruce Eckel's <a href="http://mindview.net/Books/TICPP/ThinkingInCPP2e.html" rel="nofollow noreferrer">Thinking in C++</a>. A fantastic book for already experienced programmers that want to get into the C++ mindset. 

He is kind enough to make electronic versions of his books <a href="http://mindview.net/Books/DownloadSites/" rel="nofollow noreferrer">available for free</a>.

blocks|key|2903869|text|我强烈建议任何学习C%2B%2B的人阅读Stroustrups+"The+C%2B%2B+Programming+Language“。Meyer和Eckel有很棒的东西，但没有什么比向一个决定语言应该是什么以及他打算如何使用它的人学习更好的了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2903870|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|$]]

I strongly recommend that anyone learning C++ reads Stroustrups "The C++ Programming Language." Meyers and Eckel have great stuff, but nothing beats learning from the guy who decided what the language should be and how he intended for it to be used.

blocks|key|704524|text|我也有同样的问题。我能找到的唯一一本书就是"Pro+Visual+C%2B%2B+2005+for+C#+Developers"+by+Dean+C.+Wills。这是一本很好的读物，有很好的例子，我认为这本书的角度可能就是你想要的。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|704525|entityMap|0|LINK|mutability|MUTABLE|url|https://rads.stackoverflow.com/amzn/click/com/1590596080^0|L|1K|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I had the exact same issue. The only book I was able to find was <a href="https://rads.stackoverflow.com/amzn/click/com/1590596080" rel="nofollow noreferrer" rel="nofollow noreferrer">"Pro Visual C++ 2005 for C# Developers" by Dean C. Wills</a>. It's a good read with excellent examples, and I think the angle from which the book comes is probably what you're looking for.

blocks|key|5159114|text|你需要一种完全不同的感觉来处理内存。还要考虑释放所有你不再需要的东西。在Java和C#中，您只需释放对象，内存就会为您清理干净-这在CPP中是做不到的|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5159115|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|$]]

You will need a completely differnt feeling for memory handling. Also think about freeing everything you don't need anymore. In Java and C# you just let go of your objects and the memory gets tidy up for you - you can't do that in CPP

At my university most of my classes have been in Java. I have also recently learned C# (and the Visual Studio environment) at a summer internship. Now I'm taking an Intro to Computer Graphics class and the grad student teaching the class prefers us to use C++ to access the OpenGL bindings via GLUT.

Does anyone have any good resources on how to make a good transition from Java/C# to C++? Obviously pointers are going to be a big issue, but any other things I should be looking out for? Any tutorials, guides, etc. would be very helpful!

Thanks!

在我的大学里，我的大部分课程都是用Java编写的。我最近还在一次暑期实习中学习了C# (和Visual Studio环境)。现在我正在上一门计算机图形学入门课程，讲课的研究生更喜欢我们使用C++通过GLUT访问OpenGL绑定。有没有人有关于如何很好地从Java/C#过渡到C++的好的参考资料？显然，指针将是一个很大的问题，但我还需要注意其他事情吗？任何教程、指南等都会很有帮助！谢谢!
