Life Cycle: software requirements, software design, software testing, software maintenance
Areas of specialization: Software configuration management, software project management, software engineering processes, software engineering models and methods of software quality
Rationale: calculation based on a mathematical basis, foundation engineering
2: textbooks do not understand the question
(1) For the second chapter of regression testing regression, explanation is given on the book can be understood as a "return to a previous abnormal state" do not understand. Internet search data regression testing is to modify the re-test after the old code, in order to confirm the modification does not introduce new bugs or cause other code to generate an error, both say whether there is a conflict, do not understand.
Growing content (2) software engineers, the software engineers and talked about the contrast of ordinary programmers, how to become a qualified software engineer? First of all to have good programming skills, as a qualified software engineers proficient in at least one language editing, the ability to program directly determines the efficiency of project development; a strong command of English, in the English program of the current environment, recently technical articles are inseparable and English; has a good sense of team, only the team can better solve large-scale projects.
(3) There are a lot of comments in the code, but that is necessary, is it? Internet search data there is no clear answer to this question
(4) Why do code review, wrote the book review is for developers who are in the dry developer should stem the problem, the data is written to help developers learn the code base, and help them learn new skills, thereby enhancing their skills, and that do not improve their skills not need to do a code review
(5) the definition of how a typical user? Typical users of the popular and unpopular typical user can do to contain
3: Mobile Software
(1) game: king of glory
Analysis: downloaded freshman at the time, was watching a friend play this game very interesting feeling to be downloaded from a web, is king of glory may charge money, usually when a good entertaining game, and this game Dan is fascinating is relatively easy, indulge them not so good.

(3) Living Software: Ctrip, the US group, hungry yet, railway 12306,
Because home away from home each time farther than it needs to buy train tickets, rail 12306 is the first ticket I downloaded the software, because it is the official ticketing software, to have more confidence, but the US group with Ctrip tickets deficiencies that they can not advance to grab votes, Ctrip is a focus on buying software, but the US group is more and more features, like not only can buy train tickets can also be ordering the regiment attractions tickets, etc., and hungry it is a focus on a software ordering, when this software because new customers a discount and the intensity is relatively large.
(4) Video Software: Tencent video deft iQIYI
When I bought this phone on download Tencent video, was the students by seeking qq to me face to face soon pass over. Use good, but then came out with a point of view can only play in iQIYI so I downloaded the iQIYI, both programs are members of the ad-free but relatively speaking Tencent membership would love Odd ratio Arts Member cheap, which is why the use of Tencent later than one video of the main reasons iQIYI in recent years, network video is very small fire was also recommended by the deft roommate this software, this software can not only publish video they can also see people all over the world of video, and can also be carried out to make money and live a reward, usually watch a live amusing is good.
(5) payment software: micro-channel qq Alipay
(6) School Software: Yi campus sports world report
(7) Music selfie Software: Meng excited card machine b612 Netease cloud music cool dog qq
