Refactoring your C + + knowledge system

C++, A famous programming language . As a multi paradigm general programming language , It applies to a wide range of fields , Small to embedded , Large to distributed servers , You can see... Everywhere C++ The figure of .

Its development prospects are also very broad , AI and machine learning as future trends , The coat is Python( Model describes ), But the kernel still C++( High Performance Computing ).

Besides , Almost all universities in China will offer computer majors C++ Course , It has become the first language for many people to start programming , Why? C++ It's going to get so much attention ? I concluded. 3 Point to its core competitiveness :

  • The ability to abstract : This means higher development efficiency , meanwhile , what's more , It doesn't degrade performance because of abstraction .

  • performance : Although complete the same function ,C++ The number of lines of code required may be Python Three times , And the performance can be easily achieved Python More than ten times .

  • Power waste : Whether it's a mobile device , Or the server , We all pay more and more attention to power consumption . Use C++ It usually means low power consumption , The battery can run longer , Servers spend less on electricity .

However ,C++ It's also known for its complexity 、 It's hard to learn 、 Difficult to use . It's hard to master and master , So it's also easier to make mistakes 、 mis-used . But this way , skilled C++ Programmers will naturally get “ The level is very high , The pay is high ” The reputation of . So it's not exactly a bad thing .

C++ already 40 Year old , But it's still a very popular and dynamic language . After more than ten years of silence , And finally released the second edition of the language standard ——C++11—— after ,C++ New language standards are published every three years , Each version basically retains backward compatibility at the same time , Provides improvements and new features .

These new features are daunting to many people , The cost of learning is very high —— But it's a misunderstanding . These new features and related programming practices , Just let C++ It's easier to develop a lot of things .

Wu Yongwei, former senior system architect of Intel Asia Pacific R & D center , Deep tillage C++ 20 many years , He organized a copy of  C++ Learning path , It should help you :

In the field of development , Wu Yongwei is worthy of the name “ veteran ” 了 . He 1995 Graduated from Fudan University in , Now engaged in software development work 20 many years , Previous development engineers 、 project manager 、 Development Manager 、 Architect, etc .

He delves into technology , love C++, Like open source , I have been involved in translation 《 Interview with master programmer 》,GitHub We can also see some small open source projects that he maintains in his spare time , such as libunibreak etc. .

He started a column at geek time 《 modern C++ actual combat 30 speak 》, Take you to master C++ The modern nature of language , Grasp the essence of abstract expression , Practice development idiomatic pattern , Conquer complexity and solve practical problems .

There are many cases in the column + Code , Some grammar and rule details , Mr. Wu will also provide references at the end of the article . Follow and learn , Let me understand the modern C++ With a new understanding . I believe as long as you follow , It doesn't just work C++ Write abstract but natural code , It can also better solve the practical problems in the project .

I always believed , Calm down and study hard C++, It will benefit you for life , It will also make your programming go further .

Mr. Wu's column setting is also quite attentive , From basic to advanced to actual combat , All have , It's better to have C++ My basic friends come to see :

  • The basic chapter , Explain modern C++ The most important feature of , To help you understand the basic concepts ;

  • Improve , Talk about several independent topics , Help you master C++ Some of the advanced techniques in ;

  • Actual combat , Discuss the actual tools and third-party libraries , Help you polish your arsenal ;

  • Future , Discuss C++20 Some new features to be introduced in , Help you develop forward-looking .

Here's a list of columns , You can see what you can learn :
