1) 实现对两个文件数据进行合并,生成新文件3.txt

2) 抽取出三科成绩中有补考的学生并保存在一个新文件4.txt

3) 对合并后的文件3.txt中的数据按总分降序排序(至少采用两种排序方法实现)

4) 输入一个学生姓名后,能查找到此学生的信息并输出结果(至少采用两种查找方法实现)

5) 要求使用结构体,链或数组等实现上述要求.

6) 采用多种方法且算法正确者,可适当加分. -1) The realization of the merger of the two files of data to generate a new file 3.txt 2) extracted from three subjects for students in make-up and save a new file 4.txt 3) of the merged file 3.txt in data in descending order by total score (at least in two sequencing methods to achieve) 4) Enter the name of a student, the student can find this information and the output (at least by two to find ways to achieve) 5) require the use of structure, chain or an array such as the above-mentioned requirements. 6), using a variety of methods and algorithms are correct, may be appropriate bonus.
