这个程序包含了学生宿舍信息的录入、修改，学生楼栋信息的录入、毕业生的退舍、智能分配宿舍等功能，但不能进行删除的操作，总体来说使用简单方便。
这个程序应该满足以下几个要求：（1）信息的输入：需要建立起完整的宿舍信息数据库,从而实现通过输入学生入住的楼栋号、宿舍号，该宿舍入住的人数以及入住的学生的信息（包括学生的姓名、学号和系别），来添加学生信息，实现信息录入。
（2）信息的修改：进行信息输入后，过一段时间后，想要对里面的信息进行修改，可以通过学号等关键字对其进行修改。
（3）信息的查询：这个程序应该可以实现通过按学号或房号进行查找的过程。
在此使用的是折半法，查找过程是：先确定待查记录所在的范围（区间），然后逐步缩小范围直到找到或找不到该记录为止。
这样可以缩短查找时间，同时还可以减少查找的次数。
（4）退出程序：当完成了所有的操作之后就要进行退出操作了。
2 课题分析2.1需求分析学生宿舍管理是一个很大的项目，在早期，还没有利用计算机管理时，一切都是利用人工进行管理的，这样管理起来既烦琐又复杂，资料也很容易被丢失，而且耗时、耗资金。
而利用本系统，可以高效地对学生宿舍进行统一管理与控制，资料也不容易被丢失，这样大大节省了人力与资源，提高了管理效率，给管理人员带来很多方便，基于以上分析有如下分析：（1）要实现交互工作方式，各项操作结束后均应返回主菜单。
（2）系统本无任何信息数据，要建立数据文件，需要开发一个信息录入功能，即首先创建一个学员线性表，同时我们可以将数据暂时保存在内存中，所以我们开发信息存盘功能；（3）信息录入后都要保存在内存中，用户看不到，需要设计一个信息显示功能，信息的显示应该便于查询，所以需要具备按各种关键字显示的功能；（4）由于有些新同学入校，所以设计了插入功能；（5）当用户操作完毕需要退出时，提供了退出选项，便于使用者退出交互式工作系统2.2 存储结构设计本系定义的存储结构为顺序存储结构，结构体为typedef struct{char ID[20]; //学号char name[20]; //姓名char gender[10]; //性别char dormitory[4]; //宿舍号}Student;typedef struct{char ID[4]; //宿舍号int max_num; //可容纳人数int current_num; //已入住人数char gender[10]; //男舍或女舍2.3 算法设计及其分析在此系统中，根据对查阅资料的了解，我们对宿舍人员的信息以及各种函数进行了定义，具体如下：（1）将宿舍人员信息定义为一个名字为typedef struct的结构体，其中包括char ID{20},char name[20],cahr gender[10],char dormitory[4]分别表示学号、姓名、性别和宿舍号，将宿舍信息定义为一个名字为typedef struct的结构体，其中包括char ID[4],char max_num,char current_num,char gender[10],分别是宿舍号、可容纳人数、已入住人数、男舍或者女舍。
（2）功能函数加上主函数一共有十二个，功能函数包括create()，open()，insert_dorm()，insert_stu()，dormnumsearch()，change()，namesearch()，check_out()，numsearch()，exchange()，display()，main()，分别用新增楼栋，新增宿舍信息，新增学生入住宿舍信息，毕业生退舍，互换宿舍，姓名查询，学号查询，宿舍号查询，互换宿舍，调换宿舍，职能分配宿舍，退出本系统的功能。
（3）在主函数中，使用一个while语句来选择调用主菜单中的各个功能函数。
由于本人负责新增宿舍楼栋，新增宿舍信息，新增学生宿舍信息的功能，所以操作如下：单击数字键“0”则为新增楼栋信息单击数字键“1”则为新增宿舍信息单击数字键“2”则为新增学生宿舍信息在每次操作前都要输入相应的编号。
各功能函数的具体实现如下：void create(){printf("\n请输入新增楼栋名称：\n");scanf("%s", filename);_fp = fopen(filename, "rb+");if (_fp == NULL){ //如果文件不存在则建立文件否则提示文件已存在_fp = fopen(filename, "wb+");fp = fopen(strcat(filename, "学生"), "wb+");if (fp == NULL || _fp == NULL){printf("File not open!\n");exit(-1);}}elseprintf("文件已存在!\n");fclose(fp);fclose(_fp);}void open(){printf("请输入学生宿舍所在楼栋：\n");scanf("%s", filename);_fp = fopen(filename, "rb+");fp = fopen(strcat(filename, "学生"), "rb+");if (fp == NULL || _fp == NULL){printf("File not open!\n");exit(-1);}}void insert_dorm(){Dormitory * d = (Dormitory*)malloc(sizeof(Dormitory));open();printf("\n请输入宿舍号，可容纳学生数，已容纳学生数，男舍/女舍(空格隔开，‘#’结束)：\n");scanf("%s", d->ID);while (strcmp(d->ID, "#")){scanf("%d %d %s", &d->max_num, &d->current_num, d->gender);fwrite(d, sizeof(Dormitory), 1, _fp);scanf("%s", d->ID);}fclose(_fp);fclose(fp);}void insert_stu(){long locate, pre_locate;int flag = 0;Student *s = (Student*)malloc(sizeof(Student));Dormitory * d = (Dormitory*)malloc(sizeof(Dormitory));open();printf("\n请输入学号、姓名、性别、宿舍号(空格隔开，‘#’结束)：\n");scanf("%s", s->ID);while (strcmp(s->ID, "#")){ //不相等继续读取，相等为0便退出循环不再读取数据scanf("%s %s %s", s->name, s->gender, s->dormitory);locate = ftell(_fp);while (fread(d, sizeof(Dormitory), 1, _fp)){if (!strcmp(d->ID, s->dormitory)){ //每增加一个学生，相应寝室的实际人数应当增加一个fseek(_fp, locate, SEEK_SET);d->current_num++;fwrite(d, sizeof(Dormitory), 1, _fp);flag = 1;break;}locate = ftell(_fp);}if (flag == 0){printf("不存在该宿舍！\n");exit(-1);}fwrite(s, sizeof(Student), 1, fp);rewind(_fp);scanf("%s", s->ID);}fclose(_fp);fclose(fp);}void change(){int flag = 0, tag = 0;long locate, locate_b, locate_c;char input_stunum[20];char input_dormnum[4];char previous_dormnum[4];Student *s = (Student*)malloc(sizeof(Student));Dormitory * d = (Dormitory*)malloc(sizeof(Dormitory));open();printf("\n请输入需要调换宿舍学生学号：\n");scanf("%s", input_stunum);locate = ftell(fp);while (fread(s, sizeof(Student), 1, fp)){if (!strcmp(input_stunum, s->ID)){flag = 1;printf("该学生信息如下：\n%-20s%-20s%-20s%-20s\n", "学号", "姓名", "性别", "宿舍号");printf("%-20s%-20s%-20s%-20s\n", s->ID, s->name, s->gender,s->dormitory);strcmp(previous_dormnum, s->dormitory);printf("\n请输入新宿舍的宿舍号：\n");scanf("%s", input_dormnum);locate_b = ftell(_fp);while (fread(d, sizeof(Dormitory), 1, _fp)){if (!strcmp(input_dormnum, d->ID)){tag = 1;if (d->current_num == d->max_num)printf("该宿舍已满员！");else{//更换学生宿舍信息fseek(fp, locate, SEEK_SET);strcpy(s->dormitory, input_dormnum);fwrite(s, sizeof(Student), 1, fp);//更换新宿舍信息fseek(_fp, locate_b, SEEK_SET);d->current_num++;fwrite(d, sizeof(Dormitory), 1, _fp);rewind(_fp);//更换旧宿舍信息locate_c = ftell(_fp);while (fread(d, sizeof(Dormitory), 1, _fp)){if (!strcmp(previous_dormnum, d->ID)){fseek(_fp, locate_c, SEEK_SET);d->current_num--;fwrite(d, sizeof(Dormitory), 1, _fp);break;}locate_c = ftell(_fp);}}break;}locate_b = ftell(_fp);}if (tag == 0){printf("不存在该宿舍!");exit(-1);}break;}locate = ftell(fp);}if (flag == 0)printf("\n不存在该学生！\n");fclose(_fp);fclose(fp);}void namesearch(){int flag = 0, tag = 0;long locate;char input_name[20];char dor_num[4];char ID[20];Student *s = (Student*)malloc(sizeof(Student));Dormitory * d = (Dormitory*)malloc(sizeof(Dormitory));open();printf("\n请输入需要搜索的姓名：\n");scanf("%s", input_name);while (fread(s, sizeof(Student), 1, fp)){locate = ftell(fp);
