这是一个学生成绩管理系统，其中“I”表示插入，“L”表示浏览，“Q”表示查询， “E”表示退出，“D”表示删除，“M”表示修改,"c"表示统计各分数段人数,"p"表示打印. 本程序实现了： （1）单独运行以上各功能,即在进入主菜单以后，点一功能键后关闭，再进入主菜单 点别的功能键。如运行"cjgl"文件后,在出现的主界面中点“I”，可插入数据，插入完 以后，关闭；在出现的主界面中点“M”，可修改数据，修改完以后关闭，用同样的方法 可运行其它的功能。 （2）连续运行部分的功能。-This is a performance management system for students, "I" to insert said, "L" said View, "Q" said inquiries, "E" from "D" to delete said, "M" said the amendments, "c", said Statistics the fraction of the number of "p" said Print. this procedure was realized : (a) separate operations over the function, which is to enter the main menu after a point after the closure of function keys, and entered the main menu point other function keys. To run "cjgl documents" in the main interface midpoint "I" can be inserted in the data, insert, after closing; At the midpoint of the main interface, "M", may revise the data, modify, after the closure, the same
