包括：学生基本信息，如学号，姓名，性别，年龄，等；2.学生选修课程基本信息，包括课程编号，课程名称，考试成绩，平时成绩，综合成绩，学分，重修否，若重修，需考虑重修学期，重修成绩，并考虑多次重修情况。只能用C语言，要有用户界面，必须用结构体和链表等数据结构。/*-1-*/#include #include /*头文件*/#include#include#include#include#include#include #define NULL 0#define ESC 0x001b /* 退出 */#define F1 0x3b00 /* 查看帮助信息，调用HelpMassage()函数 */#define F2 0x3c00 /*输入学生成绩*/#define F3 0x3d00 /*按学号查找*/#define F4 0x3e00 /*按姓名查找*/#define F5 0x3f00 /*列出所有学生成绩*/#define F6 0x4000 /*统计*/struct stuType /*定义结构体变量*/ char NO11; /*学号长度为10*/ char XM10; char AGE2; /*年龄长度为2*/ float CJ4; /*包含4门成绩*/;/*-2-*/int JY_NO(char *stu_num,FILE *fp) /*检验学号的正确性*/ struct stuType stud; int NO; char *p=stu_num; if(strcmp(stu_num,#)=0) return 1; /*若输入#返回真值,不再循环输入*/ while(*p!=0) /*学号必须是数字，否则返回重新输入*/ NO=(int)*p; if(NO57) puts(ttUndefined SN!Please input again!n);/*非法学号!请重新输入!*/ return 0; else p+; /*指针加1*/ if(strlen(stu_num)!=10) /*若学号长度不为10,则返回重新输入*/ puts(ttLength of SN Error!n);/*学号长度不对*/ return 0; if(getchar()!=n) /*若学号后面的字符不是回车符，则学号长度大于10*/ printf(ttThe length of SN should more than 10!Please input again!n);/*学号长度大于10个,请重新输入*/ dowhile(getchar()!=n); /*用getchar接收多余的字符*/ return 0; else rewind(fp); /*使文件指针指向头*/ while(!feof(fp) /*若文件指针未到结尾,就继续执行下面的循环,feof遇到文件结束符返回非零值,否则返回0*/ fread(&stud,sizeof(struct stuType),1,fp); /*读取一定长度的数据*/ if(strcmp(stu_num,stud.NO)=0) /*学号的唯一性*/ printf(tt Repeat SN,Please input again!n);/*学号重复!请重新输入*/ printf(ttThe Record of this student:n);/*该学生成绩如下*/ printf(ttChinese:%.1fn,stud.CJ0);/*语文*/ printf(ttMath:%.1fn,stud.CJ1);/*数学*/ printf(ttEnglish:%.1fn,stud.CJ2);/*英语*/ printf(ttTotal:%.1fn,stud.CJ3);/*总评*/ return 0; return 1; /*-3-*/int JY_NO2(char *stu_num) /*检验学号*/ int NO; char *p=stu_num; if(strcmp(stu_num,#)=0)return 1; /*若输入“#”，则返回真值结束*/ if(strlen(stu_num)!=10) /*学号长度不为10*/ puts(ttLength of SN Error!n);/*学号长度不对*/ return 0; while(*p!=0) /*学号必须用数字,若包含有字母，或其它字符则返回假值重新输入*/ NO=(int)*p; if(NO57) puts(ttUndefined SN!Please input again!n);/*非法学号!请重新输入*/ return 0; else p+; /*指针加1*/ if(getchar()!=n) /*检验学号长度是否大于10，并把多余的字符去掉*/ printf(ttThe length of SN should more than 10!Please input again!n);/*学号长度大于10个,请重新输入*/ dowhile(getchar()!=n); return 0; return 1;/*-4-*/int JY_XM(char *stu_XM) /*检验姓名*/ int PD; char *p; p=stu_XM; while(*p!=0) /*姓名只能用英文*/ PD=(int)*p; if(PD0) puts(ttName should use English, Please input again!n);/*姓名只能用英文请重新输入*/ return 0; else p+; /*使指针加1，指向下一汉字*/ if(getchar()!=n) /*姓名长度不得大于5个*/ printf(ttThe length of Name is more than 5, Please input again!n);/*姓名长度大于5个请重新输入*/ dowhile(getchar()!=n); return 0; return 1; /*字符串全为汉字返回真*/*-5-*/int JY_AGE(float stu_AGE) /*年龄只能在0100之间*/ if(stu_AGE100) printf(ttInput Error!
