In the 1980s, Dr. Bjarne Stroustrup and his colleagues at AT&T Bell Laboratories successfully developed C++ on the basis of C language. C++ language is a hybrid language, it retains all the advantages of C language, while adding object-oriented programming mechanism, we can regard C++ language as an improvement and extension of C language.
C++ is compatible with C, so programs written in C can be used in C++ almost unchanged. Compared with C language, C++ language has made a certain extension of the functions of C language, while adding object-oriented programming mechanism. The object – oriented programming mechanism is introduced to improve development efficiency. C/C++ language application is very extensive, so learning C/C++ can be used for what?
- Laboratory development
I can’t say that C++ is the best language in the world, but C++ is basically a big language for engineering students. Apart from the computer major, many engineering majors, such as telecommunications, electrical, communication and other majors, will basically use C++ in normal learning. All said C++ both process oriented and object oriented characteristics, both has a relatively good running speed, and good large-scale project development ability, it can simply dominate the university laboratory.
- The backend development
There are only a few major back-end development languages, led by Java and C++, followed by Python and Go.
- The game development
Once you’ve mastered the basic syntax of C++, it’s still a good idea to develop a game, and industry-level 3D game engines are still written in C or C++. Although I can’t finish a huge online game by myself, it’s still a good idea to start simple, write some small games, and then work your way up to a large game development team. The corresponding jobs mainly include game development engineer, game engine architecture engineer, etc.
- Client development
After all, C++ is already a mature language, so there are plenty of other development jobs to choose from besides backend development. Client development, of course. I believe most math C++ students have used C++ to write desktop software. At that time, I still use MFC, and I can write a relatively simple interface by clicking on the code book. So if you don’t want to do the back end, you can totally rely on C++ to find a job in client development. Do the client also need a solid foundation of programming and computer theory, and may also be familiar with Windows/C++ compiler link mechanism, QT client development technology system, Windows message mechanism and other technologies. So, if you are a C++ student and don’t care about the industry’s nameless job discrimination chain, finding a job in client development is also a good idea. It’s just that you may need to rethink the role of the client as opposed to backend development.
- Multimedia development
At present, multimedia technology has also penetrated into People’s Daily life, and audio and video have become a very important means for people to obtain information. Audio and video are compressed and packed according to certain rules during transmission. Video coding technology from the beginning of H.261 to h.265 today, has experienced more than 30 years of development, and all the implementation code is realized by C or C++. The latest HEVC coding standard is realized by C++ code, which is interested in learning C++ grammar, you can go to the official website of the ITU (international telecommunication union) to download the source code to view. The corresponding positions are image algorithm engineer, video coding r&d engineer, audio and video transcoding engineer, etc.
- Embedded development
The above job choices are partial to the software direction, and C/C++ there is a very large employment direction, is to do embedded. Embedded itself may be a bit of hardware, but now do anything, are hard and soft. Embedded development will also involve network programming, concurrent programming and other aspects. A common explanation might be that embedded code runs on a small system other than a traditional computer. This direction requires basic circuit theory literacy in addition to programming ability. Generally, companies recruiting for embedded development positions are mainly Internet + companies with hardware products, such as Xiaomi and Huawei. Many companies are doing work related to the Internet of things, which is hot after all. Of course, there will be other business directions, such as chips, robotics, etc.
- Artificial intelligence (ai)
Artificial intelligence, machine learning and other directions are also indispensable C or C++ language figure. It should be emphasized that although C++ language can be used in a wide range of directions, it is far from enough to only master C++ grammar. The above application fields are based on C++ language. To enter these fields, it is necessary to further study the knowledge of relevant fields systematically and to contact the content of real enterprise projects. A journey of a thousand miles begins with a single step. Now learning to program students more and more, also have a lot of people want to change careers to learn this, but most people learn the high wages are seen good prospects, but what he learned to do all don’t know, today, to share with you learn C/C + +, you can what direction development, hope to be able to help your future development direction.
Finally, when you encounter problems, it is also very important to ask big gods. It is suggested to chat with this group and discuss with seniors. You will also get a lot of help. Can also exchange learning experience, technical problems, you can get PDF books source code, tutorials and so on for free use.
