This article mainly introduces the application program written in high-level language in the computer, which is very detailed and has certain reference value. Friends who are interested must finish reading it.

Generally speaking, the application program written in high-level language is called "source program". This program is a series of human-readable computer language instructions, which can not be run directly in the computer, and needs to be translated into machine language by corresponding testimony processing program.

The applications we usually use are released after the source code is compiled and packaged, and the final result is for the user and the end customer.

The source program refers to the uncompiled text file written in accordance with certain programming language specifications, which is a series of human-readable computer language instructions; the source program is the application program written in assembly language and high-level language.

The source program cannot be run directly in the computer, and the corresponding testimony processor needs to be translated into machine language before it can be executed.

The ultimate goal of computer source code is to translate human-readable text into binary instructions that can be executed by the computer. this process is called compilation and is done through the compiler.

Program use

The source program is generally many lines of English software that can be opened in notepad and written in programming language.

The source program can only be run after it is compiled into the target program. The general target program can no longer be modified.

The software installed on our computers are all target programs. Except for the source programs of the scripting language, other source programs cannot be run directly.

Proponents of open source software believe that source programs should be provided to users so that they can modify them themselves, which is conducive to the development of the software industry. Opponents feel that this is not conducive to the protection of copyright.

If you don't know how to program, the source program can ignore it. It does not affect the normal use.

As a special part of the software, the source code may be included in one or more files. A program does not have to be written in the same format of source code. For example, if a program is supported by the C language library, it can be written in C language, while the other part can be written in assembly language in order to achieve high efficiency.

More complex software, the source program files can reach thousands of. In order to reduce the complexity, we must introduce a system that can describe the relationship between the source code and how to compile correctly. In this context, the revision control system (RCS) was born and became one of the necessary tools for developers to revise the code.

There is another combination: the source code is written and compiled on different platforms, and the technical term is software migration.
