Here is a C puzzle I like to ask my friends and colleagues. It is one of those silly puzzles that may bring a smile on your face if you aren't able to figure it out immediately.
#include <stdio.h>
int main()
{
http://blog.susam.in/2011/06/urls-in-c.html
printf("URLs in C\n");
return 0;
}
This code compiles and runs successfully even though the C99 standard doesn't mention anywhere that URLs are valid syntactic elements in C. How does this code work then?

is it like this?
http: is considered as label and the rest is considered as comment?
