①统计各开发商房产开发总建筑面积和销售总额,按销售总额从高到低排序后输出。排名开发商名称房屋总套数总建筑面积销售总额12 ②输入年份,统计该年度十二个月份房产销售的套数和销售金额。年份:2011月份销售总套数总建筑面积销售总金额12 12③统计各楼盘房屋套数、售出套数、销售金额,按销售金额从高到低排序后输出。排名楼盘名称房屋套数售出套数销售金额12 ④分别统计出售率最高的5个楼盘,从高到低排序后输出楼盘名称、楼盘房屋套数、售出套数。排名楼盘名称房屋套数售出套数出售率12 5二、总体设计对有关系统全局问题给出总体的解决方案,也就是从全局的角度考虑“怎么做”。主体数据结构由三向链表组成。录入信息时都采用后进先出式。录入楼盘时,根据开发商名称确定开发商结点。录入购房信息时,由于购房信息不包括开发商名称,故采取遍历楼盘结点的方式根据楼盘名搜索楼盘结点。修改及删除开发商时根据开发商名称查找。修改及删除楼盘结点时先根据开发商名称确定开发商结点,再根据楼盘名称在此结点下搜寻楼盘结点。删除及修改房产销售信息时先根据楼盘名称确定楼盘结点,在根据身份证号确定购房信息结点。•数据查询功能:.开发商信息查询:a）按名称查找,遍历开发商链表,找到就输出b）按房屋套数:遍历输出.楼盘信息查询:a）按楼盘名称:遍历开发商链表,没到ー个开发商结点,遍历该结点下的楼盘链，输出符合条件的楼盘信息b）按开盘日期和平米均价：遍历开发商链表,没到ー个开发商结点,遍历该结点下的楼盘链，输出符合条件的楼盘信息.房产销售信息查询：a）按身份证：遍历链表，找到符合条件的销售信息就输出并退出遍历。b）按客户姓名与购房日期:遍历链表,输出所有符合条件的销售信息。•数据统计:.统计开发商总建筑面积和销售额:在录入楼盘及购房者信息的同时就进行开发商信息的统计,输出前进行排序后输出,输出时ー页输出五个开发商信息.输入年份,统计该年度十二个月份房产销售的套数和销售金额。定义ー个结构,该结构的内容包括月份,销售套数和销售金额遍历购房信息链表,根据购房信息中的日期判断是否属于这一年,如果属于这一年的购房日期,则根据日期中的月份进行选择。待遍历完全,输出数据。.统计各楼盘房屋套数、售出套数、销售金额,按销售金额从高到低排序后输出。各楼盘的房屋套数在插入楼盘是已确定,售出套数与销售金额在插入购房信息时确定,之后再调用该统计函数时先使所有楼盘信息连成一条新链,之后排序输出。.分别统计出售率最高的5个楼盘,从高到低排序后输出楼盘名称、楼盘房屋套数、售出套数。先将所有楼盘形成一条链,同时计算出售率,之后进行排序,最后输出。三、数据结构设计对实现系统主体功能的算法所涉及的数据结构进行设计,要求用图或表进行准确、具体地描述,同时需说明数据结构的用法。开发商信息typedefstructbuilder_nodecharbuilder_name[30];charCEO[30];intall_housenum;floatall_area;floatmoney;structbuilder_node*next;structhouses_node*hnext;}BUILDER_NODE;中文字段名代码类型及长度举例开发商名称builder_namechar[30]海天房产CEOCEOchar[30]张:.房屋总套数all_housenumint300总建筑面积all_areafloat340.234总销售额moneyfloat345.23开发商链表指针*nextstructbuilder_node楼盘指针*hnextstructhouses_node功能:用来存储开发商信息楼盘信息/*・楼盘信息链结点结构**/typedefstructhouses_node(charhou_name[30];charbuilder_name[30];chardate[12];charaddress[20];floatarea;inthou_num;floatbuild_area;floatpresqm_price;charlinkman[20];charlinkphone[20];inthou_sell;floatmoney_sell;floatsell_per;structhouses_node*next;structclient*cnext;}H0U_N0DE;中文字段名代码类型及长度举例楼盘名称hou_namechar[30]开发商builder_namechar[30]开盘日期datechar[12]楼盘地址addresschar[20]占地面积areafloat房屋套数hou_numint720建筑面积build_areafloat每平米均价presqm_pricefloat联系人linkmanchar[20]“chenguoqing”联系电话linkphonechar[20]12345678901售出套数hou_sellint销售额money_sellfloat销售率sell_perfloat楼盘指针*nextstructhouses_node购房信息指针*cnextstructclient作用:存储楼盘信息购房信息结构:typedefstructclientcharclientname[20];charid[20];chardate[12];charhousetype[12];charhou_name[30];charbuild_num[10];floatbuild_area;floatpresqm_price;floatdiscount;floatactualprice;charsaleman[20];structclient*next;}CLIENT_N0DE;中文字段名代码类型及长度举例客户姓名clientnamechar[20]身份证号idchar[20]购房日期datechar[12]房型housetypechar[12]“3s2tle2w”
