一、简述题目要求:


  1、除了整数之外,还要支持真分数的四则运算,真分数的运算,例如:1/6 + 1/8 = 7/24

  2、运算符为 +, −, ×, ÷

  3、并且要求能处理用户的输入,并判断错误,打分统计正确率

  4、要求能处理用户输入的真分数,如 1/2, 5/12 等

  5、程序基于GUI 界面

  6、记录用户的对错总数,程序退出再启动的时候,能把以前的对错数量保存并在此基础上增量计算

  7、有计时功能,能显示用户开始答题后的消耗时间

  8、界面支持中文简体/中文繁体/英文,用户选择一种


 二、实现步骤:


  a、需求分析

           写一段程序可以生成GUI界面,在GUI 界面上可以进行中文简体/中文繁体/英文切换,在做题过程中需要计时并显示用户答题时间,在用户输入答案时,需要对输入的参数进行过滤,当用户输入非法文字,例如:“#,@,我不知道”等会被检测到,并给予相应的错误提示,在用户结束答题后,需要显示用户答题后的各种参数并实现可以查看错题库功能。

  b、功能设计

      逻辑结构图

 

       基本功能  

          计时功能,切换语言功能,兼容获取分式和整数参数功能,生成真分式题目以及最简分式功能,运算功能,校验答案功能。

       扩展功能

          过滤非法字符功能,题目进度功能,生成用户错题库功能

       高级功能

          多级运算功能

  c、设计实现

          为满足功能需求,下面主要写了八个函数:

public void add();      //加法运算
public void sub();      //减法运算
public void mul();      //乘法运算
public void div();      //除法运算
public void ran();      //生成题目
public void check();    //校验答案
public string StringClear(string ai)   //过滤非法字符
public void thread()  //计时功能

四、总结


   

      先来一片面包:队友之前作业都是用c++写的,都对c#比较熟悉,代码以我的为基础进行GUI转换。

      再把肉放上:首先我们设计了一套流程图,根据流程图具体分析问题,发现问题,解决问题,问题的解决方法都在博客上做了总结,我们共同编写生成题目功能,实现动态计时功能,错题库功能,语言切换功能,字符过滤功能,对话框的弹出功能,在代码复审期间我们做了加减乘除运算优化升级和代码的重构,代码格式的规范,碰到难点,便和队友lianyg(连永刚)Dialect(林方言)探讨,共同解决,连永刚同学缺点是做事慢了一点,优点持之以恒,最终找到解决方法,林方言同学缺点是对代码语法不是太熟悉,不过他确实挺好问,理解能力好。

      然后再来一片面包:经过了两天的共同奋斗,从刚开始对GUI的一无所知,到将四个GUI窗体灵活调用,最终能实现所有功能,并让界面最大程度简洁化,提高界面整洁度。

     由于要用C#做成GUI界面,并且内容新加了其他功能,下面总结一下这次我们所遇到难点

         问题一:如何产生GUI界面

            解决该问提主要是借助于VS2013平台可自动生成窗体控件,然后阅读自动生成的源码,从中学习并加以利用。

         问题二:计时功能

            由于要计时功能,使时间在窗体上动态变化,这就意味这要使用线程,从而可以保证主线程可以继续监听消息。

         问题三:过滤功能

            在用户输入答案,如果输入非法字符就会被过滤并得到提示,在这里主要是将用户输入的值转化成 char ,然后将其与 ASCII 值进行对比,从而实现此功能。

   We are a team and we work as a team!
