Enter the characters you see below Sorry, we just need to make sure you’re not a robot. This article is about the software concept. For the film, see Source Code. For “source coding”, see Data compression. This article needs additional citations for verification. Simple C-language source code example, a procedural programming language.
The resulting program prints “hello, world” on the computer screen. In computing, source code is any collection of code, possibly with comments, written using a human-readable programming language, usually as plain text. Most application software is distributed in a form that includes only executable files. If the source code were included it would be useful to a user, programmer or a system administrator, any of whom might wish to study or modify the program. The notion of source code may also be taken more broadly, to include machine code and notations in graphical languages, neither of which are textual in nature. For the purpose of clarity “source code” is taken to mean any fully executable description of a software system.
It is therefore so construed as to include machine code, very high level languages and executable graphical representations of systems. Often there are several steps of program translation or minification between the original source code typed by a human and an executable program. The earliest programs for stored-program computers were entered in binary through the front panel switches of the computer. When IBM first offered software to work with its machine, the source code was provided at no additional charge. At that time, the cost of developing and supporting software was included in the price of the hardware. For decades, IBM distributed source code with its software product licenses, after 1999. Most early computer magazines published source code as type-in programs.

Occasionally the entire source code to a large program is published as a hardback book, such as Computers and Typesetting, vol. A more complex Java source code example. Written in object-oriented programming style, it demonstrates boilerplate code. With prologue comments indicated in red, inline comments indicated in green, and program statements indicated in blue.
The source code for a particular piece of software may be contained in a single file or many files. Though the practice is uncommon, a program’s source code can be written in different programming languages. The code base of a computer programming project is the larger collection of all the source code of all the computer programs which make up the project. It has become common practice to maintain code bases in version control systems. The revision control system is another tool frequently used by developers for source code maintenance.
Computer programmers often find it helpful to review existing source code to learn about programming techniques. The sharing of source code between developers is frequently cited as a contributing factor to the maturation of their programming skills. Porting software to other computer platforms is usually prohibitively difficult without source code. Without the source code for a particular piece of software, portability is generally computationally expensive.
Decompilation of an executable program can be used to generate source code, either in assembly code or in a high-level language. Programmers frequently adapt source code from one piece of software to use in other projects, a concept known as software reusability. The situation varies worldwide, but in the United States before 1974, software and its source code was not copyrightable and therefore always public domain software. In 1983 in the United States court case Apple v.
Copyright Act gave computer programs the copyright status of literary works. In 1999, in the United States court case Bernstein v. United States it was further ruled that source code could be considered a constitutionally protected form of free speech.
