[c-prog] Linking error using templates

[saurabh jain]

Hi,
   Is it necessary to have interface and implementation of a template class in 
the same file?
If I move the implementation to a separate .cpp file and call the member 
function from another file, I get linker error : " undefined reference to ..... 
'"
Things work fine when the implementation is in the same ".h" as the 
interface/declaration.

Can anyone explain what is happening in this case?

Thanks,
Saurabh
