Circular Inclusion with Templates

Question

The following code compiles perfectly:

// MyFile.h

#ifndef MYFILE_H_INCLUDED
#define MYFILE_H_INCLUDED

template 
class MyClass
{
          


        

Answer 1

If you include the MyFile.tpp (I renamed it from .cpp), then you don't need to include the MyFile.h. #includeing a file is like exactly copying it's content into the file where it's included. Other from that, it's a common practice to organize the headers a bit. (Though you don't need the include-guards in the MyFile.tpp, because it should only ever be included from another header directly (like GMan says).)
