【源碼】C語言 + 圖形庫 = 簡單又好看的圖書管理系統！

直接上代碼，就是這么任性！

各位小伙伴也都可以去運行一下，之前也弄了一個圖書管理系統，但是今天加了個界面，需要注意的是記得安裝好圖形庫哦！

弄了一個好看的界面，順帶也加上了音樂也感覺還不錯吧，而且也比較基礎的！加油~

 

 

 

第一個圖是主要界面以及功能方面，然后就是后面兩個圖，兩個功能一個是添加功能，一個是瀏覽，涉及到的知識點也並不是很多。

    1、文件操作；

    2、graphics.h頭文件以及圖形界面庫函數；

    3、C語言基本語法與控制結構。

其實的話，編程是很有樂趣的，前提是你得喜歡這個，但是也不要局限在知識點里面了，編程思維是很重要的。

 

最后，不管你是轉行也好，初學也罷，進階也可，如果你想學編程~
