个人作业 | 易学教程

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

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
