软件工程结对项目---黄金点游戏

Posted 2020-10-10 忆杉

github源码和工程文件地址：https://github.com/HuChengLing/GoldPointGame

基本要求：黄金点游戏是一个数字小游戏。

其游戏规则是：N个同学（N通常大于10），每人写一个0~100之间的有理数 (不包括0或100)，交给裁判，裁判算出所有数字的平均值，然后乘以0.618（所谓黄金分割常数），得到G值。提交的数字最靠近G（取绝对值）的同学得到N分，离G最远的同学得到－2分，其他同学得0分。玩了几天以后，大家发现了一些很有意思的现象，比如黄金点在逐渐地往下移动。

主要功能：由用户自主输入10个数字，然后由程序自主判断哪些得分和不得分并将结果进行排行。

设计思想：将小游戏移植到安卓上，有图形界面更吸引人。

 人员：本次结对编程，我的队友是易聪，他是我的室友。他做事比较低调，默默勤劳工作。我们这次编程我们明确分工协同完成此次项目。并分别编写了博客和上传工程文件到GitHub上。
