Why is this telling me it's missing storage class or type specifiers?

I imagine if i fix whats wrong it will fix everything, but i cant figure out whats wrong.

string = char[] or char*
no string in C or C++, use one of the above. Probably the array.

Wrong. No string in C.
The original poster forgot to prepend std:: to string:
string desc; std::string desc;
not only that, but I don''t think = operators are allowed in the initialization list.
i.e.: instead of this:
do this:
i.e.: instead of this:
Item() : desc = "", weight = 0 {} do this:
Item() : desc( "" ), weight( 0 ) {} 
Your Inventory constructor is screwy. Are you coming from a Java background? In C++ we distinguish between objects and references (or pointers) to those objects. Where you assign a new Item object (created via explicit constructor invocation) to each element of inv, you''re playing havok with your system. When you perform an assignment in C++ on a data type that lacks a native assignment operator (and copy constructor as a fallback), the compiler supplies a default which performs a bitwise copy. Which may not be desired behavior.

Nah, it was just a very early version of the class, heres my new one:
