数据结构中关于查找、排序的应用。对学生的基本信息进行管理。 设计一个学生信息管理系统，学生对象至少要包含：学号、姓名、性别、成绩1、成绩2、总成绩等信息。要求实现以下功能：

1．总成绩要求自动计算；

2．查询：分别给定学生学号、姓名、性别，能够查找到学生的基本信息（要求至少用两种查找算法实现）；

3、排序：分别按学生的学号、成绩1、成绩2、总成绩进行排序（要求至少用两种排序算法实现）。

-Data structure on the search, sorting applications. Basic information on students to manage. Design a student information management system, students target to include at least: study number, name, sex, results 1 results 2, total score and other information. Requirements to achieve the following functions: 1. Automatically calculate a total score of the requirements　2. Inquiry: students were given number, name, gender, students can find basic information (required at least two search algorithms)　3, sorting: by students, respectively, No. 1 performance result 2, with a total score sort (requires at least two sorting algorithm).
