I've got:

/////////CPair.cpp:
class CPair{
   //stuff here...
}

//CPair::methods...


////////Main.cpp:
void someMethod(){
    CPair pair;
}

but it's complaining that the CPair class is undefined?!?!?! How can I get around this??? Maybe some header file? :S

generally you will have  a

1) Cpair.h file with the


class CPair{
   //stuff here...
}
 
and then a Cpair.cpp

2) Cpair.cpp which will have

#include "Cpair.h"

CPair::methods...

3.) Main.cpp

which will have

#include "CPair.h"

void someMethod(){
    CPair pair;
}


================
the reason you are getting is because the file main.cpp cannot see the declaration/definition of CPair
