How Do I Learn Open Source Programming?

A programming language can be simply understood as a language that can be recognized by both computers and people. A computer language allows programmers to precisely define the data that computers need to use and precisely what actions to take in different situations. ^[1]

The computer programming language can realize the communication and communication between human and machine, and the computer programming language mainly includes assembly language, machine language and high-level language, the specific content is as follows: ^[2]

The first computer was invented in the 1940s. At that time, various computer controls were mainly implemented by manual operations, but they were seriously inconvenient in terms of convenience. After years of development, relevant personnel proposed the use of programming languages The idea of controlling the computer, although the programming mode at that time was not perfect, but it has greatly promoted the development of computer programming languages. The computer programming language was gradually perfected in the half century that followed. With the development of society, the technological requirements in various fields are constantly increasing, which makes the development of computer programming more and more complicated and diversified. In this case, some visual and integrated language environments are beginning to emerge. Only a few keystrokes are needed to complete the writing of a piece of code, which greatly reduces the capital and time costs of computer programming. Coupled with the emergence of some high-level languages, such as

Programming languages are generally divided into low-level languages, high-level languages, and the object-oriented era. ^[1]

(1) Comprehensively consider the hardware environment in which the software runs. If in

Develop

At the current stage, in order to obtain higher application quality of computer software technology and continuously improve the level of informatization in all sectors of society, researchers in related fields are continuously improving and innovating programming languages in computers to improve The intuitiveness and ease of learning of computer programming languages enable programmers to obtain more convenient programming languages. At present, the more widely used programming languages include PHP, Java, C ++, VB, and C. Different programming languages are The application advantages are also different, so during the specific application period, you need to combine your own needs to choose a programming language with high adaptability and pertinence to ensure the advantages of the selected programming language. ^[2]

With the development and progress of science and technology, computers continue to innovate in software and hardware technologies, especially in the multi-core era, which has gradually changed the traditional form of computer architecture. Affected by this development form, computers should also do programming languages. With corresponding changes, only in this way can the information development needs of all sectors of society be better met. To achieve optimization and innovation in programming languages, it is necessary to expand from programmer operations, programming language applications, and object-oriented space. And platform independence. ^[2]

(1) To ensure the convenience of the user's various operations. As far as current computer programs are concerned, its core main lines are data abstraction and object-oriented programming. In order to make the operations of programming languages more convenient, it is necessary to ensure that programming languages are easy to learn and continue to reduce their professionalism. Taking the convenience of use as the main development direction, to ensure that users only need to master the basic concepts and operation methods, they can write some simpler programs to ensure convenient operation. ^[2]

(2) The programming language should be based on objects to achieve deep development and provide a highly dynamic interface model and simple class mechanism. Utilizing the inheritance mechanism, subclasses can apply the methods given by the parent class to achieve code reuse. In addition, the computer network itself has a strong openness. Therefore, in the future development of programming languages, security should be fully considered, so that program writing can obtain a more secure environment. Therefore, security protection should be provided. The mechanism is constructed, and the safety characteristics of the writing environment are ensured by constructing a security system in combination with the relevant characteristics of program writing. The promotion of platform independence is mainly to write programs that can be transplanted between different platforms or machines, to avoid being affected by the platform. This is also an important direction for the future development of writing languages. Under this development mode, applications will be more effective Convenient, it will get a wider range of applications. ^[2]

DSL Programming language declarative programming and DSL

Declarative programming tells a computer to calculate "what" rather than "how" to do it. ^[1]

Programming language functional programming

The code is concise and fast to develop; it is close to natural language and easy to understand; more convenient code management; easy to "concurrent programming"; hot upgrade of code. ^[1]

Programming language dynamic language

Dynamic language means that a program can change its structure when it is running. It represents a faster and simpler technology trend and will inevitably become the protagonist of building software and IT technology in the future. ^[1]

Programming languages concurrent programming

The inevitable requirement of the multi-core era. ^[1]
