What do programmers need to learn?

Programmers who only know one programming language are not good IT apes.

If you want to be a good programmer, it is obviously not enough to be proficient in only one programming language. However, there are so many programming languages, and it is impossible for us to learn them all, so what choice should we make?

In fact, we do not need to be familiar with every programming language. In its current form, all you need to do is master the three programming languages ​​that are most in demand today. To put it bluntly, these are the three best languages ​​for finding a job.

1. C language

As the most basic low-level language, C language is a must for programmers who are interested in being system engineers or architects. Prepared.

The main purpose of C language is, in addition to realizing the underlying functions of the programming language, it is also used to implement the operating system, and it also has a lot of use in the communication field.

Although relatively speaking, it is a little clumsy at the development and application level, but at the bottom level where efficiency is important, there is a huge room for development.

2. Java language

The most widely used language at present is Java.

Java is often associated with "enterprise". Because of its good language features and rich framework, it is deeply favored by enterprises. I believe you can always hear discussions about J2EE, JSP, Hibernate and the like.

At the same time, Java also has a place in the mobile phone field. Before the popularity of smart phones, most mobile phones used supporting Java applications as a selling point. After the outbreak of smartphones, the home field of mobile phones became Android, and Java continues to exist as the standard programming language of Android.

3. Python language

Python is also called the "glue language" because of its rich and powerful libraries. Various modules made in other languages ​​​​(especially C/C) can be easily connected together.

A common application situation is to use Python to quickly generate a prototype of the program (sometimes even the final interface of the program), and then rewrite the parts with special requirements in a more suitable language. For example, the graphics rendering module in 3D games has particularly high performance requirements, so it can be rewritten in C/C and then encapsulated into an extended class library that can be called by Python.

Python is mostly used in server development and IoT development. For example, information security, big data processing, data visualization machine learning, Internet of Things development, APIs of major software, desktop applications, etc.

With the rise of artificial intelligence and big data, these are all written in Python language. Therefore, Python is a good choice for students with no basic knowledge.
