说明：  编写成绩管理程序 1.要求 a) 可以按学号输入高等数学成绩和大学物理成绩，分别存储在2个数组中，之后计算总成绩，保存在另外一个数组中（在3个数组中，元素的下标就是学号）。 b) 可以按学号次序显示学生的成绩； c) 可以按总分、高等数学或大学物理成绩排序（注意：排序的时候不要改变数据元素在数组的次序，否则学号与成绩就不匹配了。可以使用一个辅助数组存储学生的学号，排序的时候只改变辅助数组的元素次序）。 d) 可以显示排序后的结果。 e) 程序要有简单的菜单。
(Write performance management program 1. Requirements a) You can input advanced mathematics scores and college physics scores according to the student number, and store them in two arrays respectively, then calculate the total scores, and save them in another array (in three arrays, the subscript of the element is the student number). b) Students' grades can be displayed in the order of student number; c) You can sort by total score, advanced mathematics or college physics (Note: don't change the order of data elements in the array when sorting, otherwise the student number and grade will not match. You can use an auxiliary array to store students' student numbers, and only change the element order of the auxiliary array when sorting. d) The sorted results can be displayed. e) The program should have a simple menu.)
