转贴：用c语言做一个图形界面"程序"
文章摘要:
这个小程序引用了c语言中的图形函数，构造了一个640*480的图形界面，其中包括了一个静态的菜单。程序中可以有一段音乐（当然是pc喇叭放出的难以忍受的音乐），可以驱动鼠标，画指定大小的圆（稍作修改一下就可画出多种图形了），执行ms-dos命令，还有一小段动画（崭且称之为动画吧，实在太不起眼了），有帮助信息提示如何操作，虽小，但应用了c给我们的较多功能。

用c语言做一个图形界面"程序"
今天看了秦岭兄的"C语言制作的下拉文本菜单"一文，突然想起我在上学期做的一次课程设计，也想发表出来，供大家品论。
这个小程序引用了c语言中的图形函数，构造了一个640*480的图形界面，其中包括了一个静态的菜单。程序中可以有一段音乐（当然是pc喇叭放出的难以忍受的音乐），可以驱动鼠标，画指定大小的圆（稍作修改一下就可画出多种图形了），执行ms-dos命令，还有一小段动画（崭且称之为动画吧，实在太不起眼了），有帮助信息提示如何操作，虽小，但应用了c给我们的较多功能。
这是我在大二开学初匆忙完成的（为了应付作业），其中有很多不当之处，比如，用了不被人看好的goto语句，没有层次等，希望大家予以指正。
标题中的引号，是因为他根本算不上什么程序，不能解决什么问题。因为看了秦岭兄的文章，才斗胆将它拿出来。以下时源代码部分，保持原文，其中还有我当时的一些充满好奇的注释，也希望能给初学者(我自己也是一个初学者)一点提示。
