Ok guys i am having a function template problem here:

Basically and finally (after a huge WORKOUT!!!) i have 5 files all working...

OrderedList.h & .cc
Member.h & .cc
Node.h & .cc
ClubTable.h & .cc  - Basically the HashTable
and finally the main.cc


Now the problem is that where do i actually put the function templates - in the .cc of the upper files or the main.cc??
Thats the first question the rest will follow on.

Put them in a separate header (.h) file that is included by all the .cc files that need to use the function templates, otherwise you probably will get linker errors.

there is no separate header file? i mean we have a question here in a book.... it says that

how could your program be adapted to using templates which deals with any data type?

Then create one or put them in a .h file that is included in all .cc files anyway.

if there is only one main.cc you can put all into that file.

That is ok for assignment projects where you don't use the classes/structs of previous lessions. But if you have the requirement to reuse the classes in further projects or if you use more than one cpp/cc file, you *have* to put the class definitions to separate header files which can be included by any cpp/cc file. In case of template classes put the implementation to the header file as well - as already told above - cause the implementation was needed for any concrete template type used.

When creating header files you should protect them for getting included twice by adding

#ifndef  HEADERFILENAME_H
#define HEADERFILENAME_H

put here all the rest
...

#endif // HEADERFILENAME_H
