一、
随着互联网的快速发展，文件传输和共享变得日益频繁。在传输过程中，了解文件的 MIME 类型对于正确处理和显示文件内容至关重要。MIME 类型是一种用于标识文件类型的机制，它由类型和子类型两部分组成。例如，文本文件的 MIME 类型可能是 "text/plain"。文件扩展名通常与 MIME 类型相对应，例如，".txt" 扩展名通常表示文本文件。
Snobol4 语言因其强大的文本处理能力，在处理文件扩展名与 MIME 类型匹配问题时具有独特的优势。本文将介绍如何使用 Snobol4 语言编写一个程序，该程序能够读取文件扩展名并输出相应的 MIME 类型。
二、Snobol4 语言简介
Snobol4 是一种高级编程语言，由 J. E. Hopcroft 和 J. D. Ullman 在 1966 年设计。它是一种基于规则的语言，主要用于文本处理。Snobol4 的语法简洁，易于理解，特别适合于模式匹配【5】和字符串操作。
Snobol4 的基本语法包括以下元素：
- 变量【6】：用于存储数据。
- 运算符【7】：用于执行算术和逻辑运算。
- 控制结构【8】：用于控制程序的流程。
- 文本模式：用于匹配字符串。
三、文件扩展名与 MIME 类型匹配程序
以下是一个使用 Snobol4 语言编写的简单程序，用于匹配文件扩展名与 MIME 类型。
