课程设计实验报告
班级：光电104—2 姓名：刘云龙 学号：201058501220

一、实验题目：使用C语言编写一个小游戏（拼图游戏）

二、实验目的：C语言是每一个通信学生的必修课之一，此次课程设计要求我们使用C语言编写一个小游戏，在完成课程设计的过程中，加强了我们对C语言的综合应用。虽然在平时的课堂上积累了很多的理论知识，但在实际应用时还是有很多不明白的地方。为了更好地完成实验要求，通过翻课本，请教同学，在网上查找资料等途径解决了试验中遇到的疑难。在完成实验的过程中，暴露了自己在C语言学习上的很多不足和缺陷，同时也解决了很多平时不明白的地方。

三、实验内容
本次试验选定的实验项目是使用C语言编写一个拼图游戏
以下是拼图游戏的源代码：

四、实验结果
选择这个小游戏的时候，没有想到会有这么难做，开始做甚至不知道从哪里下手，问了很多的人，加上上网查阅，最后才把这个小游戏做出来。不过，这个游戏还是有很多可以改进的地方的，尤其哈斯关于无解的情况。对于这个问题，我改动了很多地方还是不行，也尝试换成不同的玩法拼图，不过都是没有做出来。尽管有很多需要改进的地方，但是看着自己制作的拼图游戏能够玩，还是很有成就感的。希望以后自己能够做出更多更好地小程序。
