2、=(structstudent*)malloc(sizeof(structstudent));//创建一个节点printf("====请输入学生信息二===");printfC请输入学生学号:”)；scanf("%s",p->xuehao);while(strcmp(p->xuehao,M0M)!=0){end=p;printf(H姓名:“)；scanf(”％s”,p->name);printf(”性别:“)；scanf(M%s",p->xingbie);printf("年龄:“)；scanf(H%d'&p->nianling);printf(M电话:“)；scanf(n%d'&

3、p->dianhua);printf(H证件号:“)；scanf("%s",p->licence);printf(”家庭住址:“)；scanf(H%s'*,p->address);printf(n邮箱:“)；scanf('*%s",p->youxiang);p=(structstudent*)malloc(sizeof(structstudent));end->next=p;//end=p;printfC*请输入学生学号:“);scanf(H%sH,p->xuehao);}end->next=NULL;returnhead;voidsave(structstudent*head)//保存

4、链表为磁盘文件{FILE*fp;structstudent*p;charfilename[20];intch;printf(M请输入要保存的文件名:”)；scanf("%s",filename);if((fp=fopen(filename,nrn))!=NULL){printfC*该文件已经存在，是否覆盖？M);printf(Ml>覆盖.2、不覆盖“)；scanf(”％d“,&ch);if(ch!=l){printfC*请重新输入要保存的文件名:”)；scanf("%s",filename);}}if((fjp=fopen(filename,',w"))==NULL){print

6、ddress);fprintf(fp/'%s",p->youxiang);p=p->next;}fputs(noverM,fp);printf(H文件保存成功!“);〃getchar();fclose(fp);}voidoutput(structstudent*head)〃输出链表{structstudent*p;p=head;if(p=NULL){printf(”未创建任何记录!”)；getchar();return;//head;}while(p!=NULL)//do{printf(M学号：%s'p->xuehao);printf(H姓名：%sM,p->name);
