1、学生管理系统 define CRT SECURE NO WARNINGS include include include voidAppendNode longlong studentID char studentName 10 char studentSex 4 int score 4 添加数据 voidDisplayNode structlink head 显示数据 voidInsertNode longlong studentID char studentName 10 char studentSex 4 int score 4 插入一条数据 按总分的从大到小排序 voidInsertN
2、odeNumber longlong studentID char studentName 10 char studentSex 4 int score 4 按学号的从小到大排序 voidNumberSorting int flag 按从大到小对数据进行排序 1 对总分 进行排序 2 对学号进行排序 voidDeleteNodeID 输入学号删除 voidDeleteNodeName 输入学号删除 voidDeleteMemory structlink head 删除聊表所占用的内存 voidSave 保存数据 voidOpen 打开数据 voidFindID 按学号查找学生 voidFind
3、Name 按姓名查找学生 voidMenu typedefstructstudent longlongstudentID charstudentName 10 charstudentSex 4 intscore 4 STU structlink STU student structlink next structlink head NULL 保存输入的学生信息数据 structlink head1 NULL 保存排序后的学生信息数据 intmain longlongstudentID charstudentName 10 charstudentSex 4 intscore 4 定义要输入学生信
4、息的变量 charc intmenu 保存要进行的选项 Open while 1 system pause Menu printf 请输入要进行的操作 scanf d switch menu case 0 exit 0 break case 1 printf 请输入 Y或y来添加数据 n scanf c while c y c Y printf 请输入学生学号 scanf lld printf 请输入学生姓名 scanf s printf 请输入学生性别 scanf s inti 0 printf 请分别输入学生四门课的成绩 for i 0 inext NULL pr pr next pr n

11、udent studentID studentID strcpy p student studentName studentName strcpy p student studentSex studentSex p student score 0 score 0 p student score 1 score 1 p student score 2 score 2 p student score 3 score 3 sum p student score 0 p student score 1 p student score 2 p student score 3 if head1 NULL
12、head1 p else sum1 pr student score 0 pr student score 1 pr student score 2 pr student score 3 while sum1 sum pr pr next sum1 pr student score 0 pr student score 1 pr student score 2 pr student score 3 if sum1 next head1 head1 p else pr temp p next pr next pr next p else pr next p return voidDeleteNo
13、deID 输入学号删除 structlink p head pr head longlongstudentID 0 if head NULL printf 对不起 没有数据可以删除 return printf 请输入你要删除的学生的学号 scanf s studentID while studentID p student studentID p p next if studentID p student studentID if p head head p next else pr next p next free p else printf 你要查找的这个数据未找到 return void
14、DeleteNodeName 输入姓名删除 structlink p head pr head charstudentName 10 if head NULL printf 对不起 没有数据可以删除 return printf 请输入你要删除的学生的姓名 scanf s studentName while 0 strcmp studentName p student studentName p p next if 0 strcmp studentName p student studentName if p head head p next else pr next p next free p
15、 else printf 你要查找的这个数据未找到 return voidSave 保存链表中的数据 FILE fp structlink p head if fp fopen demo txt w NULL printf 打开文件失败 return while p NULL fprintf fp 20lld 10s 5s 4d 4d 4d 4d p student studentID p student studentName p student studentSex p student score 0 p student score 1 p student score 2 p studen
16、t score 3 p p next fclose fp return voidOpen 将文件中获得的数据写入到链表中 longlongstudentID charstudentName 10 charstudentSex 4 intscore 4 FILE fp charc if fp fopen demo txt r NULL printf 文件打开失败 return while c fgetc fp EOF fscanf fp 20lld fscanf fp 10s studentName fscanf fp 5s studentSex fscanf fp 4d fscanf fp 4d fscanf fp 4d fscanf fp 4d AppendNode studentID studentName studentSex score fclose fp voidFindID structlink p head longlongstudentID 0 if head NULL printf 没有数据查找 return printf 请输入你要查找的学生的学号 scanf ll
