What should a programmer know?

Programmer is one of the most important professions. In most modern spheres of activity, computers are used, and a specialist of the corresponding profile is the main one who is responsible for their practically significant functions for a person, and in many respects for their performance. What skills should a programmer have to successfully solve his problems? What basic knowledge does a person need to become such a specialist?

We can study the competencies of a programmer in the following main aspects:

  • features of tasks solved by a person in a given specialization, as well as the necessary skills correlated with them and knowledge;
  • the specificity of individual software development languages ​​as the main components of a programmer's toolkit.

Let us consider the essence of the noted aspects in more detail.

What should a programmer know to solve his problems?

A person working as a programmer can deal with a large number of problems. These include:

  • writing computer programs;
  • development of software concepts;
  • adaptation of programs to different categories of users (in terms of interface and functions);
  • testing and debugging software.

Let us study the essence of these areas of activity of programmers, as well as what skills they must have to successfully perform the corresponding functions.

Language competence

Writing programs is the main competence of a specialist in the profile under consideration. "Soft" is created using special languages, and a person will have to master the appropriate level of proficiency in them. This is thus a key requirement for a programmer's knowledge.

As for the first task, software can be developed for the internal needs of the company (for example, for the purpose of organizing work with databases and equipment, managing financial flows) or for an external consumer (within the framework of a corporate order or by bringing the product to a retail market under a commercial brand).

What programming languages ​​should a programmer know? It largely depends on what kind of software he creates. Within the framework of internal corporate tasks, the programmer most often works with databases, servers, debugging, testing, writing equipment control algorithms. These competencies will most likely require knowledge of universal, multifunctional languages: C, C, Java, Ruby. When it comes to working with databases, you can't do without SQL proficiency. Knowledge of Python will be useful to a specialist - one of the easiest to learn, but very necessary and demanded language.

Thus, a novice programmer should not be a certified mathematician, but have the ability to understand the principles of constructing formulas, building various logical dependencies, working with variables, etc. All this will come in handy when creating software.

Successful mastering of all the programming languages ​​discussed above presupposes knowledge of English. The point is not only that it is used as the main one when writing various commands and scripts. A significant amount of documentation and quality training materials are written in English. Moreover, their authors are not necessarily British or Americans. Many developers from China, India, Russia use English as the main language for publishing various materials and communicating with colleagues.

When creating this or that kind of software, if we are not talking about a learning process or an experiment, a programmer must roughly understand who will be the final consumer of the product. In this sense, a specialist will need basic knowledge from the field of marketing, possibly sociology and other humanitarian spheres, which allows him to study the characteristics of the target groups of users of the solution.
