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, that define a student information (student number, name, results) of the order of the table, you can not consider the case of the same name, the system contains at least the following functions: (1) In accordance with the designated student number, enter individual students　(2) one by one to display the information of all students in the student table　(3) given the student information inserted into the location specified in the table　(4) delete the specified location, student records　(5) Statistics Table of middle school students number　(6) the use of direct insertion sort or binary insertion sort to sort by name　(7) the use of quick sort sort according to student number　(8) binary search by name, require the use of a recursive algorithm successfully return According to the student number, the number of students and grades　(9) binary search, require the use of non-recursive algorithm to achieve successful return to the student&#
