Apologies for starting with a negative comment, but why use C if you aren't going to write a cross platform timer?
The problem is not with C itself, the language is quite portable - until you hardcode platform specific includes such as windows.h, which in this case is redundant.
I don’t see where the author mentions cross platform?
Judging by the looks of the code the author is learning C. Creating something useful in a new language is a nice way to learn IMO.
That's reasonable. I think I misunderstood because it was on the front page - I assumed it was showing a neat new thing rather than someone exploring a something new to them. My bad. It's a shame I can't delete my original comment.
