menu(); do printf("ttPlease choice you number(1-5)"); scanf("%d",&n); if(n<1|n>5) w=1,getchar(); else w=0; while(w=1); switch(n) case 1:regist();break; case 2:stati();break; case 3:search();break; case 4:modify();break; case 5:exit(0); void menu () /*菜单函数*/ printf("ttt*客房管理系统*n"); puts("nttt (1).登记 n"); puts("ttt (2).统计 n"); puts("ttt (3).查询 n"); puts("ttt (4).修改 n"); puts("ttt (5).退出 n"); puts("nt*n"); void return_confirm(void) printf("n按任意键返回n"); getchar(); #include "stdio.h" #include "string.h" /在使用中要用到的字符串都包含在本文件中#include "stdlib.h" #include "math.h" #define NUM 50 struct Client char Name20; int Sex; /famale 0,male 1; int Age; char ID_card20; /*居民身份证*/ int year; int month; int date; /*住店时间*/; struct Hotel char Room_ID10; /*房间号*/ char Tel10; int Price; /*住房单价*/ int Sign; struct Client Client_list; /*实现两个结构体的嵌套*/RoomNUM; 注:menu函数能提供菜单方式选择功能,可以根据用户需要进入到所想要的操作模块中,此外把menu函数独立出来,可以方便随时对它进行调用,容易返回到系统界面。并用结构体来存放客户信息。2、各功能模块函数部分:(1)输入模块:需求分析 对信息进行输入程序:void regist() /*登记函数*/ void printf_one(int i); void save(int n); void printf_back(); int load(); void printf_face(); int i,n,c; n=load(); do for(i=0;i<n;i+) if(Roomi.Sign=1) printf("Room%s has been fulln",Roomi.Room_ID); else puts("nregister new recordn"); printf("n Room%s is empty",Roomi.Room_ID); printf("nplease enter Room%s's information",Roomi.Room_ID); puts("nplease enter customer's Namen"); scanf("%15s",&Roomi.Client_list.Name); printf("nplease enter Sex and Agen"); scanf("%3d %3d",&Roomi.Client_list.Sex,&Room i.Client_list.Age); puts("nplease enter customer's ID_cardn"); scanf("%20s",&Roomi.Client_list.ID_card); printf("nplease enter year and month and daten"); scanf("%5d %5d %5d",&Room i.Client_list.year,&Roomi.Client_list.month,&Room i.Client_list.date); Roomi.Sign=1;/把房间标记为已满 printf_face(); printf_one(i); printf("nn Are you sure?nnt1.suret2.cancle and againt3.Back without save bb"); scanf("%d",&c); if(c=1) save(n); printf_back(); else if(c!=2) menu(); while(c=2);return_confirm(); int load() FILE *fp; int i; if(fp=fopen("Hotel.txt","r")=NULL) printf("nCannot open filen"); exit(0); for(i=0;!feof(fp);i+) fscanf(fp,"n%s%s%d%d%s%d%d%s%d%d%dn",&Room i.Room_ID,&Roomi.Tel,&Roomi.Price, &Roomi.Sign,&Roomi.Client_list.Name,&Room i.Client_list.Sex, &Roomi.Client_list.Age,&Room i.Client_list.ID_card, &Roomi.Client_list.year,&Room i.Client_list.month,&Roomi.Client_list.date); fclose(fp); return(i); void printf_one(int i) printf("n%-5s %5s %5d %d", Roomi.Room_ID,Roomi.Tel,Room i.Price,Roomi.Sign); printf("n%-s %5d %5d %10s",Roomi.Client_list.Name,Room i.Client_list.Sex,Roomi.Client_list.Age,Roomi.Client_list.ID_card); printf("n%-5d %5d %5dn", Roomi.Client_list.year,Room i.Client_list.month,Roomi.Client_list.date); void save(int n) FILE *fp; int i; if(fp=fopen("Hotel.txt","w")=NULL) printf("nCannot open filen"); exit(0); for(i=0;i<n;i+) fprintf(fp,"%-5s %-15s %-5d %-5d %-15s %-5d %-5d %-20s %-5d %-5d %-5dn",Roomi.Room_ID,Roomi.Tel,Roomi.Price,Roomi.Sign, Roomi.Client_list.Name,Roomi.Client_list.Sex, Roomi.Client_list.Age,Roomi.Client_list.ID_card,Roomi.Client_list.year, Roomi.Client_list.month,Roomi.Client_list.date); fclose(fp); void printf_face() printf("nRoom_ID Tel Price Sign"); printf("nName Sex Age ID_card"); printf("nyear month date"); void printf_back() int w; printf("nntSuccessful.-nn"); printf("Do you want to back?nnt1).Yest2).No: bb"); scanf("%d",&w); if(w=1) menu(); 本函数的功能为登记用户及房间信息,包括姓名、性别、年龄、年份、月份、日期及身份证、。系统依次分配房间号并定义此房间为非空。管理员可根据具体情况登记相应用户人数的信息。在此申明由于本程序并未将用户信息存入磁盘,因此务必先登记用户信息再执行功能菜单中的其他功能。(2)统计模块:需求分析 该模块的功能是显示所有客户记录信息。程序:void stati() /*统计函数*/ void Time_stati(); void Room_ID_stati(); void Price_stati(); int c; do puts("nnstatistic by =>nn1).Time2).Room_ID 3) Price"); printf("Which you need<1-3>?: bb"); scanf("%d",&c); if(c>3|c<1) puts("nChoice errror!Please again!"); getchar(); while(c>3|c<1); switch(c) case 1:Time_stati();break; case 2:Room_ID_stati();break; case 3:Price_stati();break; return_confirm(); void Time_stati() /*统计入住的时间*/ int n,i,k=0,w,w0=1,w2=0; struct Hotel s; n=load(); do do w=-1; puts("nplease enter the time that you want to statistic.n"); puts("nplease enter the year:"); scanf("%d",&s.Client_list.year); puts("nplease enter the month:"); scanf("%d",&s.Client_list.month); puts("nplease enter the date:"); scanf("%d",&s.Client_list.date); for(i=0,k=0;i<n;i+) if(s.Client_list.year=Room i.Client_list.year&&s.Client_list.month=Room i.Client_list.month&&s.Client_list.date=Roomi.Client_list.date) w=i; printf_face(); printf_one(i); k+; printf("nThere are %d recorders this day!",k); if(w=-1) printf("nNO exist!please. Enter error!"); printf("nThere are no recorders this day!"); printf("nDo you want to retry another?nnt1).Yes 2).No and back 3).Back to menu bb"); scanf("%d",&w0); if(w0=2) stati(); else if(w0!=1) menu(); else printf("nSuccessful!_ _.nEnter another time?nnt1).Yes 2).Back to menut bb"); scanf("%d",&w2); if(w2!=1) menu(); while(w=-1&&w0=1); while(w2=1); void Room_ID_stati() /*统计房间号*/ int n,i,k=0,w,w0=1,w2=0; struct Hotel s; n=load(); do do w=-1; puts("nplease enter the Room_ID that you want to statistic.n"); scanf("%s",&s.Room_ID); for(i=0,k=0;i<n;i+) if(strcmp(s.Room_ID,Roomi.Room_ID)=0) w=i; printf_face(); printf_one(i); k+; printf("nThere are %d recorders in this Room!",k); if(w=-1) printf("nNO exist!please. Enter error!"); printf("nThere are no recorders in this Room!"); printf("nDo you want to retry another?nnt1).Yes 2).No and back 3).Back to menu bb"); scanf("%d",&w0); if(w0=2) stati(); else if(w0!=1) menu(); else printf("nSuccessful! _ _.nEnter another Room_ID?nnt1).Yes 2).Back to menut bb"); scanf("%d",&w2); if(w2!=1) menu(); while(w=-1&&w0=1); while(w2=1); void Price_stati() /*统计房间单价*/ int n,i,k=0,w,w0=1,w2=0; struct Hotel s; n=load(); do do w=-1; puts("nplease enter the Room's price that you want to statistic.n"); scanf("%d",&s.Price); for(i=0,k=0;i<n;i+) if(s.Price=Roomi.Price) w=i; printf_face(); printf_one(i); k+; printf("nThere are %d recorders at this price!",k); if(w=-1) printf("nNO exist!please. Enter error!"); printf("nThere are no recorders at this price!"); printf("nDo you want to retry another?nnt1).Yes 2).No and back 3).Back to menu bb"); scanf("%d",&w0); if(w0=2) stati(); else if(w0!=1) menu(); else printf("nSuccessful!.nEnter another Room'price?nnt1).Yes 2).Back to menut bb"); scanf("%d",&w2); if(w2!=1) menu(); while(w=-1&&w0=1); while(w2=1); 本函数的功能为输出统计功能菜单选项,包括根据按性别统计、根据年龄统计及根据入住时间统计。系统根据输入的选项执行相应的函数。(3)查找模块程序: void search() /*查找函数*/ int i,n,k,w1=1,w2,w3; struct Hotel s; n=load(); do w2=-1; do k=-1; printf("nnEnter ID_card that you want to search! ID_card:"); scanf("%s",&s.Client_list.ID_card); for(i=0;i<n;i+) if(strcmp(s.Client_list.ID_card,Room i.Client_list.ID_card)=0) k=i; w2=1; printf_one(k); break; if(k=-1) printf("nnNo exit!Please."); printf("nnAre you again ?nt1).again 2).No and back bb"); scanf("%d",&w1); if(w1!=1) menu(); while(k=-1&&w1=1); if(w2=1) printf("nnSuccessful._.n"); printf("nWhat do you want to do?nt1).Search another 2).Back to menu bb"); scanf("%d",&w3); if(w3!=1) menu(); while(w3=1); 本函数的功能为输出查询功能菜单选项,包括根据房间号查询、根据姓名查询及根据性别查询。系统根据输入的选项执行相应的函数。(4)修改模块需求分析 该模块的功能是插入客户记录信息并且不能覆盖原有客户信息。程序:void modify() /*修改函数*/ int modify_date(int i,int k); struct Hotel s; int i,n,k,w0=1,w1,w2=0; n=load(); do k=-1; printf_face(); for(i=0;i<n;i+) if(i!=0)&&(i%4)=0) printf("nnRemember Room_ID that you need to modify! Pass any key to continue ."); getchar(); puts("nn"); printf_one(i); do printf("nnEnter Room_ID that you want to modify!Room_ID:"); scanf("%s",s.Room_ID); for(i=0;i<n;i+) if(strcmp(s.Room_ID,Roomi.Room_ID)=0) k=i; s=Roomi; if(k=-1) printf("nnNo exist! Please again"); while(k=-1); printf_face(); printf_one(k); w1=modify_date(k,n); if(w1=1) printf("nnSuccessful _ _.nAre you modify another?nnt1).Yes 2).Back with savet bb"); scanf("%d",&w0); w2=1; else w0=0; if(w2=1) Roomi=s; if(w0!=1&&w2=1) save(n); while(w0=1); menu(); int modify_date(int i,int k) int c,w1; do puts("nnmodify by =>nn 1).Name 2).Sex 3).Agen 4).ID_card 5).Time 6).All data 7).Cancle and back"); printf("Which you need?: bb"); scanf("%d",&c); if(c>7|c<1) puts("nChoice errror!Please again!"); getchar(); while(c>7|c<1); do switch(c) case1:printf("Please enter new Name:");scanf("% s",&Roomi.Client_list.Name);break; case 2:printf("Please enter new Sex:");scanf("% d",&Roomi.Client_list.Sex);break; case 3:printf("Please enter new Age:");scanf("% d",&Roomi.Client_list.Age);break; case4:printf("PleaseenternewID_card:");scanf("%s",&Roomi.Client_list.ID_card);break; case5:printf("Pleaseenternewyearmonthdate:");scanf("%d%d%d",&Roomi.Client_list.year,&Roomi.Client_list.month,&Room i.Client_list.date);break; case 6:printf("Please enter new All data
