Thread: Template class

I had my template class with two-file organization

Code:

// MyClass.h
#ifndef MY_CLASS_H
#define MY_CLASS_H

template <class T>
class MyClass {
...
};

#include "MyClass.cpp"
#endif

//MyClass.cpp
#include "Myclass.h"
...

I included this class in my main program (#include "Myclass.h") and everything worked untill at some point after I added some stuff in my main program and add another class it gives me error "template function has already been defined" for every single member function in the template class. I could get away from getting that error by putting evertyhing in one file "MyClass.h" but I kinda like the two-file organization above.
So, what's wrong
Note that everything runs fine with two files when I compile using g++ but not .NET

Code:

//The template class 
#ifndef DICT_H
#define DICT_H

class Dictionary
{
...
... };

#endif

//The .cpp file needs
#include "dict_h.h"

Code:

//Main needs to include both
#include "dict_h.h"
#include "diction.cpp"

void main ()
{
	Dictionary x;
	x.readDict ();
	return;
}

Hope this helps to clear things up for you

NEVER #include a .c or .cpp.

>#include "MyClass.cpp"
>#include "diction.cpp"
There's no need to include a .cpp file. When the object files are linked together everything will be fine. You do need to include the header files so that everything will compile before linking though.

>void main ()
I'm surprised you have so many posts and still haven't stopped using void main. Main returns an int, always. Void doesn't even save you keystrokes anymore by allowing you to omit the return statement. Standard C++ returns 0 by default if main returns int and the return statement is omitted. So using void is one character less efficient than int. And there's this little matter about undefined behavior, but it pales in comparison to the one character difference in source code size.

Hooiii, you guys! Did you know that we're talking about template class ?
Anyway, I'm gonna go for one file .h(declaration and definition in one file). It seems to be the most common way; I looked up MSDN as well. I tried keyword export but .NET does not support it. What still puzzles me is that the method that I mentioned on my first post worked one time on .NET but never work again since then. It always works on g++, tho. But whatever, I made up my mind with one file template class
