【源码】C语言 + 图形库 = 简单又好看的图书管理系统！

直接上代码，就是这么任性！

各位小伙伴也都可以去运行一下，之前也弄了一个图书管理系统，但是今天加了个界面，需要注意的是记得安装好图形库哦！

弄了一个好看的界面，顺带也加上了音乐也感觉还不错吧，而且也比较基础的！加油~

 

 

 

第一个图是主要界面以及功能方面，然后就是后面两个图，两个功能一个是添加功能，一个是浏览，涉及到的知识点也并不是很多。

    1、文件操作；

    2、graphics.h头文件以及图形界面库函数；

    3、C语言基本语法与控制结构。

其实的话，编程是很有乐趣的，前提是你得喜欢这个，但是也不要局限在知识点里面了，编程思维是很重要的。

 

最后，不管你是转行也好，初学也罢，进阶也可，如果你想学编程~
