C++ is Tencent’s most popular programming language. With the further development of cloud computing and microservice-related technologies, Go is the fastest growing language and has surpassed JavaScript to become the second most popular programming language in Tencent. At the same time, TypeScript, with its architecture and compatibility, is the second fastest growing language in 2020 and the most promising front-end language.
Tencent to C++ so much attention, the author personally think or with this programming language itself!
C and C++ are the necessary paths to truly learn programming, and the guidelines to always come back to. When you as a programmer, the longer, the more feel the importance of the underlying language, so again turn head to consider, every review to have further understanding of the programming world, the use of such a lot of grammar is let nature take its course, learning is more and more easily, to realize one day, you can put the knowledge system of c + + is simplified to a two pages of content, Use it to guide the learning of other languages, this is not a programming field in the “Jiuyang miracle”?
No one says you have to be crazy to learn it well. The importance of C++ is to explain “object-oriented programming ideas”, not how familiar you are with its library (STL). The best way to learn an idea is not to get too hung up on its grammatical form. Because you understand the idea of object-oriented programming, its library is a bunch of algorithms and classes that you already have, and you just use them. Use it a few times and you’ll be good at it. So knowing how to use things in the library doesn’t tell you how deep you’ve developed them, because you haven’t developed them.
Learning c + + and don’t think too complicated, it is easily to use abstract data structure, the complex algorithm to confuse yourself, to scare people, programming world really deep water, knowledge update speed is fast, so hard is inevitable, so it is difficult to learn programming said, scared beginners trembling with no faith, this is not a skill. To say complex things easily is called skill. Is the question worth pondering for the “preacher”.
Only by learning the essence of the programming world (C/C++), which is not the language you must learn to work in Tencent, but by practicing the internal mental skills, can you have fast learning ability and be competent for the ever-changing needs of the future work.
