I'd guess that what's holding up the program is printing to the console output, which is a slow process. Try writing to a file instead and it'll probably help with speed. Then see if you need to...

Actually.
The #include thing only works on compile time. Not run time. So you can't strcat the value of the #include.
Also, your first example mightn't work the way you think.

I think you might have to return a reference/pointer to the stream. Though if it's a local variable you might have to return a dynamically allocated stream.
