[C++]Unresolved externals

[P1X3]

Programm.cpp [url]http://pastebin.com/uaUa1jxL[/url]
Array.h [url]http://pastebin.com/XRr2zqEP[/url]
Array.cpp [url]http://pastebin.com/LqtuNajx[/url]

Whenever a class member that is implemented in cpp is invoked, I get the unresolved externals error.
Moving the implementation to header gets rid of the error, but then header will be a mess.

Must of missed something minor

First I didn't think that this was possible, but when I searched for a possible solution and found this:
[url]http://stackoverflow.com/questions/115703/storing-c-template-function-definitions-in-a-cpp-file[/url]

So it seems that you might be missing
[CPP]
template <class T>
[/CPP]
before each function declaration in your array.h .
Then in your array.cpp file add definitions for the types you want to use the templates with
for example like this:
[CPP]
using namespace std;
template void Array::Add<string>(string* str);
template bool Array::Delete<string>(string* str);
template int Array::Delete<string>(string*, bool delete);
template string* Array::Each<string>();
[/CPP]

Or if you don't know what types you are going to use, atleast I think that, you need to define the function bodies in your header.

Also as the solution in the link above suggested you should read
"-- 35.12, 35.13, and 35.14 from the C++ FAQ Lite:
[URL]http://www.parashift.com/c++-faq-lite/templates.html[/URL]"

However, please note that I'm not the worlds most experienced C++ programmer so I might have made a mistake somewhere, but I'm glad if I could be of any help.

Thank you. Helped to clear few things out of the way.

So if I move implementation into a header should I expect any issues other than longer compile times?

Well, this is what I had to do in my own project.
I haven't noticed an increase in the compile times because of this. So I think it won't cause any issues
and this is the recommended way (I think) if you don't know what classes are needed to have the templates.
