I'm getting an error in main() saying TitledEmployee is an undeclared identifier?

That's because you've got it buried in the Employees namespace. Use its full name: Employees::TitledEmployee frank; Have fun.

Thanks for the C++ help!

Ok, I just took the namespace out completely. Now i get this

1>assign18.obj : error LNK2028: unresolved token (0A00032B) "public: void __thiscall TitledEmployee::setTitle(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> >)" (?setTitle@TitledEmployee@@$$FQAEXV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z) referenced in function "int __cdecl main(void)" (?main@@$$HYAHXZ)

edit] maybe because I didn't define it.

That's just the compiler's obnoxious way of saying that you declared a method named TitledEmployee::setTitle but didn't define it anywhere.

What compiler are you using, BTW?
