Want to be a good programmer, believe that these seven skills must be mastered, is the basic skills, they are: arrays, strings and hash tables, regular expressions, debugging, two languages, a development environment, SQL language, writing software ideas. The role of these 7 types of weapons is described below.

arrays, strings, and hash tables

Any professionally trained programmer will not be unfamiliar with the various data structures involved in the course of "data structure", but in actual programming, most data structures will not be used and will never be used. Even so, a thorough understanding of the conceptual and implementation details of basic data structures remains a task for every programmer. This is not only because mastering these knowledge will help to apply them more correctly and flexibly, but also because the thirst for the details behind the language is the quality of a good programmer.

Regular expressions

In the day-to-day work of programmers, data processing occupies a considerable proportion. And all the data in the text occupies a considerable proportion. Text can be understood, with good transparency, conducive to system development, testing and maintenance must have a certain law to follow a rule, when you master a regular expression language, you can develop intuitive instincts of programming, to achieve a higher level, but also in practice to provide higher development and execution efficiency.

Debugging

Software debugging is an important part of software engineering, its process appears in every stage of software engineering, from the initial feasibility analysis, prototype verification, to the development and testing phase, and then to the release of maintenance and support, there are software debugging process involved. Learning and flexible application of software debugging technology, not only can improve the efficiency of programmers, but also conducive to the sense of the code and control, deepen the understanding of software and systems. In addition, debugging technology is a kind of effective weapon to solve all kinds of software problems, it has obvious advantages over other indirect methods. Software has great beauty, debugging see true work!

Two languages

Any professional software technician will use the programming language as its own weapon. They represent the developer's understanding of the computer itself and the persistence of the software development effort. At the same time, building on the basis of programming language also marks the development of the professional path of the programmer to a new stage, and a single language has some limitations, the essence of software development is to process information and data. A scripting language designed to handle data is often one of the necessary weapons to become more professional. So proficiency in both languages is not necessary for any developer, but is often necessary for a highly specialized developer.

A development environment

As technology advances, the IDE has become more and more powerful, far beyond our original image, more and more content is covered in the IDE, from requirements analysis, business to build a large number of software releases, the IDE has gradually covered the entire lifecycle of software development.

SQL language

Speaking of SQL, most programmers have a clear sense of what their role is-to access the database. Indeed, data is the core of information systems, and computer applications without data have no meaning. In an information system, a large amount of data exists essentially as an entity-relational model, while an RDBMS supports a simple but expressive provider of SQL, as well as built-in transaction acid property assurance and failure recovery capabilities--so RDBMS naturally becomes the standard data storage medium for most information systems. So, no matter what language you use to develop information systems, from C, C++,delphi to Java, from Perl to Python to Ruby, using SQL to access an RDBMS is a skill we have to cultivate.

The idea of writing software

Talking about the nature of the programmer's weapons, technical books, they are like Kenji, sword, although not immediately converted into a huge damage output, but the time to study hard, one day become alongside body knowledge is also perhaps. However, although a variety of technical books voluminous, to remove the introduction of easy-to-use references and complex esoteric academic monographs, can make all programmers often see the new method cheats or not much.
