源代码 Source code
（重定向自Programming code）
源代码（英语：Source code），也称源进程，是指一系列人类可读的计算机语言指令。
在现代进程语言中，源代码可以是以书籍或者磁带的形式出现；但最常用的格式是文本文档，这种典型格式的目的是为了编译出计算机进程。计算机源代码的最终目的是将人类可读的文本翻译成为计算机可以执行的二进制指令，这种过程叫做编译，通过编译器完成。

In computing, source code is any collection of computer instructions (possibly with comments) written using some human-readable computer language, usually as text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by a compiler program into low-level machine code understood by the computer. The machine code might then be stored for execution at a later time. Alternatively, an interpreter can be used to analyze and perform the outcomes of the source code program directly on the fly.
