C语言图书管理系统课程设计.doc

题目：图书管理系统要求：能录入新图书；能浏览图书信息；能自主查询图书信息；能修改图书信息；能删除图书信息。程序如下：#include#include#includetypedef struct char number10;/书号char name20;/书名char author20;/作者char publish50;/出版社char time20;/出版时间float price;mbook;typedef struct int count;/书的本数mbook book100;/最大可有100本书mlibrary;mlibrary library;void save()/保存图书信息。FILE *fp;if(fp=fopen(library.doc,w)=NULL)printf(n不能保存图书信息n);return;fwrite(&library.count,sizeof(int),1,fp);fwrite(library.book,sizeof(library.book0),library.count,fp);void putin() /*定义录入函数*/ int y=1;system(cls);while(y) printf(t请输入您的书籍的书号:);scanf(%s,library.booklibrary.count.number);printf(t请输入书名:);scanf(%s,);printf(t请输入作者名:);scanf(%s,library.booklibrary.count.author);printf(t请输入出版社:);scanf(%s,library.booklibrary.count.publish);printf(t请输入出版时间:);scanf(%s,library.booklibrary.count.time);printf(t请输入该书的价格:);fflush(stdin);scanf(%f,&library.booklibrary.count.price);library.count+;printf(n是否继续录入(1.继续;0,退出录入):);fflush(stdin);scanf(%d,&y);if (y!=1)y=0;break; save();void lookup()system(cls);printf(图书号t图书名t作者名t出版社t出版日期t图书价格n);for (int i=0;ilibrary.count;i+)printf(%st%st%st%st%st%6.2fn,library.booki.number,,library.booki.author,library.booki.publish,library.booki.time,library.booki.price);fflush(stdin);getchar();void search_by_name() /*定义按书名查询*/ char s220; int flag=1;printf(n请输入要查询的书名: );fflush(stdin);scanf(%s,s2);printf(图书号t图书名t作者名t出版社t出版日期t图书价格n);for(int i=0;ilibrary.count;i+ )if(strcmp(s2,)=0) flag=0;printf(%st%st%st%st%st%6.2fn,library.booki.number,,library.booki.author,library.booki.publish,library.booki.time,library.booki.price); if (flag)printf(cannot found!);fflush(stdin);getchar();void search_by_author() /*定义按作者名查询*/ char s320;int flag=1;printf(请输入要查询的书的作者: );fflush(stdin);scanf(%s,s3);printf(图书号t图书名t作者名t出版社t出版日期t图书价格n);for(int i=0;ilibrary.count;i+ )if(strcmp(s3,library.booki.author)=0) flag=0;printf(%st%st%st%st%st%6.2fn,library.booki.number,,library.booki.author,library.booki.publish,library.booki.time,library.booki.price); if (flag)printf(cannot found!);fflush(stdin);getchar();void search() /*定义查询函数*/ int a;system(cls); /*进行清屏*/ printf(tt*n);printf(开始查询n); printf(ttt1-search_by_namen); printf(ttt2-search_by_writern); printf(ttt0-exitn); printf(tt*n) ; printf(tt请选择你想要的查询方式:);fflush(stdin); scanf(%d,&a); switch(a) case 1:search_by_name();break; case 2:search_by_author();break;case 0:return;void del() /*定义删除函数*/ char number10;system(cls); /*清屏*/printf(n Please type in the number of the book you want to delete:);fflush(stdin);scanf(%s,number);int i;for (i=0;ilibrary.count;i+)if(strcmp(number,library.booki.number)=0)break;if (i!=library.count)for(;ilibrary.count-1;i+)strcpy(,library.booki+1.name);strcpy(library.booki.number,library.booki+1.number);strcpy(library.booki.publish,library.booki+1.publish);strcpy(library.booki.author,library.booki+1.author);strcpy(library.booki.time,library.booki+1.time);library.booki.price=library.booki+1.price;library.count-;elseprintf(n cannot found!n);save();fflush(stdin);getchar();void update()/修改图书信息char number10;system(cls); /*清屏*/printf(n Please type in the number of the book you want to delete:);fflush(stdin);scanf(%s,number);int i;for (i=0;ilibrary.count;i+) if(strcmp(number,library.booki.number)=0) printf(图书号t图书名t作者名t出版社t出版日期t图书价格n); printf(%st%st%st%st%st%6.2fn,library.booki.number,,library.booki.author,library.booki.publish,library.booki.time,library.booki.price); break; if (i!=library.count)mbook book;printf(ntt请输入修改后此图书的信息n);printf(t请输入图书号:);scanf(%s,book.number);printf(t请输入图书名:);scanf(%s,);printf(t请输入作者名:);scanf(%s,book.author);printf(t请输入出版社:);scanf(%s,book.publish);printf(t请输入出版时间:);scanf(%s,book.time);printf(t请输入该书的价格:);fflush(stdin);scanf(%f,&book.price);strcpy(,);strcpy(library.booki.number,book.number);strcpy(library.booki.publish,book.publish);strcpy(library.booki.author,book.author);strcpy(library.booki.time,book.time);library.booki.price=book.price;save();elseprintf(n cannot found!n);fflush(stdin);getchar();void main()FILE *fp;if(fp=fopen(library.doc,r)=NULL)printf(n不能打开图书信息库n);fp=fopen(library.doc,w+);printf(n初始化图书信息库,初始化之后要重启程序n);library.count=0;fwrite(&library.count,sizeof(int),1,fp);fclose(fp);return;fread(&library.count,sizeof(int),1,fp);fread(library.book,sizeof(library.book0),library.count,fp);fclose(fp);int a; do system(cls);printf(nnnnntttt图书信息管理系统ttttn);printf(tt*n);printf(ttt1 -图书信息录入n);printf(ttt2 -图书信息浏览n); printf(ttt3 -图书信息查询n);printf(ttt4 -图书信息删除n);printf(ttt5 -图书信息修改n);printf(ttt0 -退出图书信息系统n);printf(tt*n);pri
