Template classes and friend functions

[Dohojar]

I created a class for a growning array. The array can get bigger or
smaller depending on what I want to do with it. Now I had written all
the code for this class and designed it around an int array type and the
code worked fine. So then I make this array class into a template class and
I am getting linker errors. Now I know this is caused by the friend function
I have inside this class(well I think I know). my question is this, it there
a differnt way to declare friend functions in a template class than normal...
argh.

I don't think the errors are caused by the friend declaration. It's hard
to guess what exactly is wrong without seeing the code and the error
messages, but you should remember that unlike ordinary classes and
functions, templates' definitions (i.e., implementation) should appear
in the same translation unit as the declarations. In other words, if
your class a separate .h file and a .cpp implementation file, you
should move all the .cpp contents into the .h file.
