Seven Essential weapons for programmers

Seven basic skills of programmers: array, string and hash table, Regular Expression Expression Language, debugging, two languages, a development environment, SQL language, the idea of writing software.

Array, string, and hash table

Any professionally trainedProgramClerk, there is no stranger to the various data structures involved in the "Data Structure" course, but in actual programming, most of the data structures will not be used, and will never be used. Even so, an in-depth understanding of the concept and implementation details of the basic data structure is still a task for every programmer. This is not just because Knowledge It will be helpful to apply them more correctly and flexibly, and it is also because the curiosity for implementation details behind the language is a quality of excellent programmers.

Regular Expression

In the daily work of programmers, data processing accounts for a considerable proportion. Text in all data accounts for a considerable proportion. The text can be understood and transparent, and is conducive to system development, testing, and maintenance. Therefore, a certain rule must be followed. When you master a regular expression language, it can cultivate your intuitive instinct for programming and reach a high level. It can also provide higher development and execution in practice. Efficiency .

Debugging

Software Debugging is an important part of software engineering, and its process appears in each stage of software engineering, the software debugging process is involved in the initial feasibility analysis, prototype verification, development and testing, maintenance and support after release. Learning and flexible use of software debugging technology not only improves Program Staff efficiency, and is conduciveCodeTo enhance the understanding of software and systems. In addition, the debugging technology is an effective weapon to solve various software problems. It directly hits the key and cannot be blocked, compared with other indirect Method Has obvious advantages. The software has great advantages. debugging is really helpful!

Two languages

Any professional software technician willProgramming LanguageAs your own weapon. They represent developers' understanding of computers and their attachment to software development. At the same time, it is built on Programming Language The Foundation also marks a new stage for the professional development of programmers, and a single language has certain limitations. The essence of software development is to process information and data. A scripting language dedicated to data processing is often one of the essential weapons for becoming more professional. Therefore, it is not necessary for any developer to be proficient in two languages, but it is often necessary for a developer with a high degree of specialization.

A Development Environment

With the advancement of technology, the IDE has become more and more powerful, far beyond our original image, more and more content is covered in the IDE, from demand analysis, business building a large number of software releases, IDE has gradually covered the entire lifecycle of software development.

SQL language

Speaking of SQL, the vast majority of programmers are very familiar with its role-it is used to access the database. Indeed, data is the core of the information system, and computer applications without data have no significance. In information systems, a large amount of data essentially exists in the entity-link mode, while RDBMS supports access interfaces that are as simple as SQL but with rich presentation capabilities, at the same time, it also provides built-in transaction acid features and fault recovery capabilities-therefore, RDBMS naturally becomes the standard data storage medium for most information systems. Therefore, no matter what language we use to develop information systems, from C, C ++, Delphi to Java, from Perl, python to Ruby, using SQL to access RDBMS is a secret that we must cultivate.

Idea of writing software

Speaking of programmer weapons Nature Technical books are indispensable. They are like boxing scores, swords, and classics. Although they cannot be converted into huge damage output immediately, it is not possible to study them on a regular basis and become an out-of-band one day. However, although various technical books are full of resources, apart from easy-to-use reference and complex and profound academic monographs, there are still not many secrets that can be seen by all programmers.
