从最高到最低对字符串数组和双数组进行排序(并行数组）并对齐文本

好吧，我会咬一口，这个程序确实会从最高到最低对数字进行排序，但只有当数字按从高到低的顺序排列时，它才会进行排序；如果是偶发性的，就不会。这里有两个例子来说明我的意思。

示例1:12,11,10,9,8,7,6,5,3,2.1。

示例2:32,25,24,31,10,11,15,16,8,19,18,5。

你可以看到，在例子2中，有些数字是按顺序排列的，比如32 25 24，但有些数字不是。这是我的主要问题。我的第二个问题是将文本垂直对齐，使其看起来整洁。我应该用setw left，right吗？请给予反馈。

注1：我使用的IDE是代码块。

注意2：请记住，无论用户为某个特定月份输入的数字是多少，都必须垂直平行。

注3：我很确定问题出在我的选择排序上。所以你真的应该看看函数void selectionsort，因为这是完成所有排序的函数。我只是不知道我的分类哪里出了问题。其他一切似乎都井然有序。
