I'm doing a very simple content managment system. We have a database of 3 tables; booze, cars and houses. User can add tuple (x, y) to respective table, where x is type and y is amount.
Reason for this trivial software is to learn a second language aside Java.
Simple monolithic programs (1 file main.cpp) from course are straightforward, but in example I present (see attachment) classes are not recognized in other files.
Can someone please take a look? It's very fustrating to receive error's when I'm not sure of the cause.
