1、X X 師 范 大 學 實 驗 報 告課 程 C語言課程設計 任課老師 學 號 姓 名 院 系 _年_月至_年_月 注意事項1. 使用C語言，代碼已在vs中運行過，可以運行（主要功能都能實現）2. 需求分析，前期設計都沒寫，請同學們自己完成3. 附帶有 student.txt 文件，將其移動至 F:stu 文件夾中，運行程序時可直接選 6號指令，從中讀取學生信息。如果沒有該txt文件（可能會在上傳過程中丟失），仍需在F盤下新建stu文件夾，各文件將保存于該文件夾中4. 按word格式輸出尚未設計好，有興趣可自己完成5. 按excel格式輸出，完成后需自行調整相應列寬（拉寬），使內容美觀6. 從
