<需求分析>
老陈希望通过一款软件来储存自己出的题，然后让孩子自己去做并给出评价，
1，用户可以输入题。
2，可以储存用户输入的题。
3，可以通过用户输入的题进行出题。
4，可以做出评价。
<设计思路>
1，创建windows窗体，设计窗体，并根据窗体进行编码。
2，首先创建储存文件夹。
3，写一个储存的方法。
4，然后是读出用户所出的题。
5，写一个判断正误的方法。
<代码实现>

<测试>
<总结>
刚开始写时真的没有一点头绪，不知道怎么实现写入，不用数据库不知道怎么保存，就是写入了也会清空上次的数据，终于不再清空上次的了，但是又不知道怎么一个一个的读出来，只能读出一个，但是最后还是一个一个的实现了。感觉自己增长了不少，同时有感觉很有成就感。知道了代码的严肃性，懂得了有时候看似不起眼的位置其实起了很大的作用。
