1、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
