源程序是指未编译的按照一定的程序设计语言规范书写的文本文件。

源代码（也称源程序），是指一系列人类可读的计算机语言指令。

在现代程序语言中，源代码可以是以书籍或者磁带的形式出现，但最为常用的格式是文本文件，这种典型格式的目的是为了编译出计算机程序。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-Source code is not compiled in accordance with certain standard programming language written in text files. Source code (also known as source code), is a human-readable computer language instructions. In modern programming languages, source code is the form of books or tapes, but the most common format is a text file, this typical format is intended to build a computer program. The ultimate goal of computer source code is translated into human readable text of the binary instructions a computer can perform this process is called compilation, completed by the compiler
