_X X 师 范 大 学 实 验 报 告课 程 C语言课程设计 任课老师 学 号 姓 名 院 系 _年_月至_年_月 注意事项1. 使用C语言，代码已在vs中运行过，可以运行（主要功能都能实现）2. 需求分析，前期设计都没写，请同学们自己完成3. 附带有 student.txt 文件，将其移动至 F:stu 文件夹中，运行程序时可直接选 6号指令，从中读取学生信息。如果没有该txt文件（可能会在上传过程中丢失），仍需在F盘下新建stu文件夹，各文件将保存于该文件夹中4. 按word格式输出尚未设计好，有兴趣可自己完成5. 按excel格式输出，完成后需自行调整相应列宽（拉宽），使内容美观6. 从下一页开始，复制余下全文，粘贴即可运行#include#define M 30 /班级总人数，暂定30，可修改#define N 3 /课程成绩门数，暂定3，可修改 int inputstu(struct student stu, int m, int n);void prinstu(struct student stu, int m, int n);int sortsno(struct student stu, int m);int sortage(struct student stu, int m);int sortmark(struct student stu,int sm, int m, int n);void prinsort(struct student stu, int m, int n);int writefile(struct student stu, FILE *fp, int m, int n);int readfile(struct student stu, FILE *fp, int m, int n);int fprinword(struct student stu, FILE *fp, int m, int n);int fprinexcel(struct student stu, FILE *fp, int m, int n);int seachsno(struct student stu,long sno, int m,int n);int seachsname(struct student stu,char sname, int m, int n);int desno(struct student stu, long sno, int m);int desname(struct student stu, char sname, int m);int cutin(struct student stu, int m, int n);
