举例来说，如果试图编译程序时由于存在无法解析的符号而失败了，那么就可能是编译过程前面某个步骤出现了问题！

For instance, if the attempt to compile a program fails due to unresolved symbols, it's possible that an earlier phase of the build process did something wrong!

从编译程序中符号表的总体组织和表项属性信息组织来看，符号表是一种算法复杂性很高的数据结构，而且也不利于用户与图形界面的交互。

Symbol table is data structure which has high arithmetic complexity from whole structure and items' attribute information, and it is inconvenient for users to interact with graphic interface.
