我现在要写一个程式， 要求输入3个学生的姓和名（分开来输入姓，名）， 然后输入这3个人的3个成绩， 然后算出平均分， 输出 是三个人的名字， 三个人的成绩， 三个人的平均分数， 还要输出谁的分数最高， 谁的最低， 谁的在中间

输出应该像这样：

王  90， 90， 90，  平均：90   最高
李  80， 80， 80，  平均：80   中间
张  70， 70， 70，  平均：70   最低

但是前提一定要是用class来编写

这个程式我差不多写完了， 但是最后比谁高谁低的，我是先把他们的平均分按从小到大排了， 但是现在排列出了点问题，大家帮忙找一找我的错误。（在最下面）

我帖子从新编过了， 大家再看看，帮帮忙

我写得不对么？？？

你写的对，但是我刚刚改过我程式了， 你再看看 （我注释的部份）， 不知道哪错了，不能排列

你的排序是什么排序方法阿？？
稀奇古怪的。

呵呵，楼主写的好多啊~~
