I wrote an article about how to learn C language well yesterday and someone asked me how to learn C ++ well. So I wrote some of my learning experience here, hoping to help you. First, we will only talk about C ++ because we have learned about algorithms and systems in C language.
- C ++ is the most difficult language. The most difficult programming language in the world may not belong to C ++. Do not think that the learning curves of C ++ and C ++ can be quite Bt in a few days. You can read this article. C ++ is a very free language, and it is a bit Bt and scary. I even think C ++ is not a mature programming language, because it is too easy to make mistakes. So,You must have a very cautious attitude at the beginning, and treat c ++ as a tough beast..
- Ask the question "Why ?". When learning C ++, you must ask the following questions: "Why is this?" and "why. For example, many people know that C ++ has a copy constructor and an initialization list, but do you know why copy constructor is required? Why is there an initialization list? Why is there a template and rtti? Why not? Is it to make a language cool? This is not the case at all. Any feature in C ++ has some real reasons,You must understand why C ++ should be designed so that you can learn C ++ well.. Take a look at C ++ evolution and design.
- Reading books, a large number of C ++ books. You can read these books in the order below (it took me about 4-5 years and I am still reviewing them today)
- C ++ primer, this preliminary reading may make you suffer, and read the features and why of all languages. Of course, the C ++ programming language written by the father of C ++ is also good. Just read one of the two books (I am reading the former ).
- Understanding the syntax of C ++ is only the first step in the long journey. You also need to take a look at Objective C ++ and more
The two books of Objective C ++ are not very thick, but I have been seeing them since 02 years ago. Every time I read them, I have a new experience. These two books are too classic. If you are not familiar with the C language, these two books will let you go back to the C language class.
- Think in C ++ is also another classic book. It is required to learn C ++, but the translation of the Chinese version is not good. So read the English version.
- "C ++ meditation" is also worth reading. It is very precious to teach not programming but thinking.
- Predictional C ++ and more
Predictional C ++ shows you how to solve various problems and some common classic errors.
- Advanced C ++ and modern
C ++ lets you know the magical usage of C ++.
- Generic programming and STL is something that puts C ++ into practice. Very powerful. STL-a god-like Template Library (containers, algorithms, and function objects.
- In-depth exploration of the C ++ object model allows you to understand what C ++ is under the compiler, and the performance of C ++ is not bad. This is too critical for C ++ programmers. I have previously written "C ++ virtual function table Parsing" and "c ++ Object Memory layout" in this category.
- Comparison with Java. I personally think Java has made a lot of adjustments, specifications, and restrictions on the immature C ++ language. So, let's compare Java and C ++ and think about why some things can be done in C ++, but not in Java. For example, a Java exception must be caught. Otherwise, the compilation fails. Why does Java not provide Operator Overloading? Why does Java introduce interfaces for multi-inheritance? Why is there no I/O compaction stream like C ++ in Java? Why does Java not support pointers? Why can Java achieve garbage collection? And so on.Java embodies a lot of object-oriented design things. Learning Java helps you learn how to better use C ++ for programming..
- Object-Oriented Design. Although object-oriented may be a scam. However, I think some practices in object-oriented design are very good, such as the single principle and dependency inversion principle. Design patterns must be read, and object-oriented analysis and design can be read.However, the design mode cannot be centered for programming, but the design mode should be used to solve the problem..
- Class Library Learning. Let's take a look at how MFC encapsulates windows APIs, How ace is object-oriented, how boost is object-oriented, and how cppunit is designed. Of course, there are too many design patterns in Java JDK. For details, refer.
I hope it will not scare you, and you are welcome to add it.
----- Update 2011/03/30 19:20 ----
Update several points of view:
- 1) I am not good at writing book reviews, so the recommended books may make you feel a little confused. You can go to Douban or China-pub to check the book reviews.
- 2) C ++ has many odd tricks, some of which are BT, including virtual function tables. Some may think it is boring, but I think it is interesting, on the one hand, you can understand the implementation details of a language, and on the other hand, you can broaden your thinking. I have benefited a lot from learning this knowledge.
- 3) The above is my personal learning experience. I think it is very effective for me.
- 4) There are many and many such articles on the Internet. I am not the first to write such an article, nor do I write the best. I don't want to talk about it in a long article. I just want to show you the approximate learning style. After all, C ++ is profound and profound, and cannot be said in any article. It is easier.
