Error: missing type specifier

I'm trying to do my first application on C++ using MVC pattern. So, I have a view class, ClientTsFrm, and the ClientTS class, the controller. To notify to the view class, I decided to use the Observer pattern, so ClienTS heritages from Subject.h.

ClientTsFrm has a member called ClientTS in order to do a communication, but when I build the project, it shows this error:

Error 51 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int (src\lib\ClientTS.cpp) TeamTranslate

Error 50 error C2143: syntax error : missing ';' before '*' (src\lib\ClientTS.cpp)

Hope someone could help me. If you need more code, just let me know please.

Thank you for your time.
