软件工程结对作业01

程序设计思路：先设计一个页面让用户进行选择自己所需要进行的服务类型，在根据选择的不同的选项跳转到不同的页面再次进行进一步的具体选择。然后根据用户的选项去生成不同的算式存到数据库中，在输出出到web页面上，用户输入得到的结果后在将数字和数据库中的结果进行比对，如果错误就保存错误的题号在最后将错误的题号。

编程的总结和体会：

　　在这个构建整个网页的的过程中，我渐渐体会到了程序代码和一个软件之间的差别，刚开始写小的程序时我可以在一个文件或者几个文件里写，但随着规模大的扩大渐渐地构建整个程序有了困难，除了差错无法准确的定位，并且存在一些逻辑上的错误，更是无法及时纠正，中间出现可很多错误，我也向同学和朋友请教问题所在，也借鉴了同学的意见和建议，做出了这个简单的网页程序，，中间还有许多小的bug和我也没有发现的错误。我会记住这个我的第一个小小的项目，在以后的学习和工作里改正我的错误。以后我会有提高的。
