Re: [Dev-C++] Is it possible - templates (.h and .cpp) ?

Hi,
    excuse me but I'm just a newbie in C++ (most of my developpements 
are made in ANSI-C) but was curious about the subject and made some 
google search and found this URL: 
http://www.cplusplus.com/doc/tutorial/tut5-1.html. There, the author 
says at the end the following:

/The macro-like functionality of templates, forces a restriction for 
multi-file projects: the implementation (definition) of a template class 
or function _must_ be in the same file as the declaration. That means we 
cannot separate the interface in a separate header file and we must 
include both interface and implementation in any file that uses the 
templates. /

/Going back to the library of functions, if we wanted to make a library 
of function templates, instead of creating a header file (*.h*) we 
should create a "template file" with both the interface and 
implementation of the function templates (there is no convention on the 
extension for this type of file other than there be no extension at all 
or to keep the .h). The inclusion more than once of the same template 
file with both declarations and definitions in a project doesn't 
generate linkage errors, since they are compiled on demand and compilers 
that allow templates should be prepared to not generate duplicate code 
in these cases. /




    Hope this helped.
