Thread: C++ Classes, includes and so forth

Hello,

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.

Thanks,

In CMS.h, you should add

Code:

#include "Table.h"

right before the class definition, so the compiler can find the 'Table' class.

Also in 'Table.h' add:

Code:

#include <multimap>

and change

Code:

multimap<uint32_t, uint32_t> items;

to

Code:

std::multimap<uint32_t, uint32_t> items;

Finally in 'Table.cpp' you write:

Code:

#include <iostream>
#include <map>
#include <stdint.h>
#include <unistd.h>
using namespace std;
#include "Table.h"

You should generally avoid the 'using namespace xxx' commands, but if you want to use it, put it after all #include's.

Wow many thanks! I was able to fix everything with your help.
