  • 计划

            计划需要八天时间

  • 开发

            需求分析

                        作为排球比赛的现场工作人员,我需要统计每一名队员的得分及技术统计,以便于颁发最有价值成员奖确定赛会的最佳阵容

           生成设计文档

                       把每个人是怎么得分的用详细的数据记录下来

            设计复审

                        由小组成员讨论 负责进行

            代码规范

                        根据Visual Studio 2010规范写

            具体设计

                      

            具体编码

代码复审

和小组成员一起进行了代码复审 代码可以正常运行

测试  

   无错误

报告

   计算工作量

        差不多一周的时间

 事后总结

      这是新学期的第一次迭代,感觉效率不高,不知道如何下手 过了个寒假对代码又陌生了  在接下来的时间 要继续打代码 手要勤快 要多想  多练习 希望以后自己能把代码好好练练 加油吧
