设计并实现一个学生管理系统，即定义一个包含学生信息（学号，姓名，成绩）的的顺序表，可以不考虑重名的情况，系统至少包含以下功能：

　　(1) 根据指定学生个数，逐个输入学生信息；

　　(2) 逐个显示学生表中所有学生的相关信息；

　　(3) 给定一个学生信息，插入到表中指定的位置；

(4) 删除指定位置的学生记录；

(5) 统计表中学生个数；

(6) 利用直接插入排序或者折半插入排序按照姓名进行排序；

(7) 利用快速排序按照学号进行排序；

(8) 根据姓名进行折半查找，要求使用递归算法实现，成功返回此学生的学号和成绩；

(9) 根据学号进行折半查找，要求使用非递归算法实现，成功返回此学生的姓名和成绩。-Design and implement a student management system, namely the definition of a student information (student number, name, results) of the sequence table, can not consider the same name, the system contains at least the following functions: (1) according to the specified student number, enter individual students　(2) display information for all students in the student table one by one　(3) to set a student information and inserted into the location specified in the table　(4) Delete the specified location of student records　(5) Statistics table the number of secondary school students　(6) the direct insertion sort, binary insertion sort to sort by name　(7) quick sort to sort according to student number　(8) binary search based on name, requires the use of a recursive algorithm to achieve successful return according to student number, student number and grades of students　(9) binary search requires the use of non-recursive algorithm, the successful return of the names and achievements o
