这个程序我已编译出现了下面的问题：
d:\microsoft visual studio\vc98\bin\2\book.h(5) : error C2504: 'Publication' : base class undefined
d:\microsoft visual studio\vc98\bin\2\tape.h(5) : error C2504: 'Publication' : base class undefined
d:\microsoft visual studio\vc98\bin\2\出版系统.cpp(5) : error C2059: syntax error : 'PCH creation point'
d:\microsoft visual studio\vc98\bin\2\出版系统.cpp(6) : error C2334: unexpected token(s) preceding '{'; skipping apparent function body
d:\microsoft visual studio\vc98\bin\2\出版系统.cpp(23) : fatal error C1004: unexpected end of file found
实在不知道该怎么修改，求大神解救！
