| 摘 要： | 主要讨论了如何利用C＋＋来实现VCT2．0数据库文件的格式检测。利用C＋＋中文件输入输出流和字符串处理功能，根据《城镇地籍数据库标准》和《土地利用数据库标准》中对VCT2．0数据库文件中分隔符和拓扑关系等格式信息的相关定义，完成了VCT2．0数据库文件的读取，文件格式错误检测，输出相关错误报告。

| Abstract: | The back-check of the format of VCT2.0 database file based on C＋＋ is discussed. Read file into memory character by the function of file instream and outstream in C＋＋.In terms of separator in Standard For Urban Cadastral Database and Standard For Land Use Database.Divide file stream into many strings, and compare with keyword in Standard For Urban Cadastral Database and Standard For Land Use Database.Accordingly make sure which part of file have read into memory. According to rule of different part in Standard For Urban Cadastral Database and Standard For Land Use Database, we can confirm whether the format has mistakes. |
