数据结构课设图书管理系统

梦里梦外; 2023-01-03 09:19 109阅读 0赞

在做这个课设之前本来是打算用easyx写的 但是最后发觉easyx+链表的写法 对自己而言等于写不来

所以最后还是花了一个晚上写了个黑白类型的(因为时间比较赶所以还是调用了很多别人直接的框架,将就看吧)

    #include<string.h>
    #pragma warning(disable:4996)//可以利用该代码消去警告类
    
    #define Max 2 //定义最多能借几本书的宏定义
    #define NEW1 (book *)malloc(sizeof(book))
    #define NEW2 (RD*)malloc(sizeof(RD))
    //---------------------------------------------------三个结构体变量定义----------------------------------------
    typedef struct book { 
    	char book_num[10];//图书编号???
    	char book_name[20];//图书名称?
    	char book_writer[10];//图书的作者?
    	int book_xkc;//现有量
    	int book_zkc;//库存
    	int n; 
    	struct book *next;
    }book;
    
    
    typedef  struct borrow
    { 
    	char jy_num[10];//借书的总数
    	char limit_date[40];//还书日期 防止溢出的问题
    }BO;
    typedef struct reader
