@fum2006 This works but it is contra intuitive, so i wouldn't use it unless you want to code something that is difficult to understand, or you need to show off OR you really need those 4/8 bytes of memory. But cool trick, Richard Buckland would say it is hackerish ^^.

should teach them about const early!

An aside - to swap ints without using a temp:
a=b-a
b=b-a
a=b+a

*(30:27) "That's C we got to live with it". C is a fools game rethink to D#++ using Pimp OS.

best explaintion of the use of pointers is definetly the swap idea.
Otherwise I know how to use pointers but no idea when I have to use em.. thanks for this..
still confused with the scanf.. since it returns 1 char why couldnt it work like getchar? bad coding when C programming was being coded? some drunken coder or what
Maybe the scanf supports multiple inputs i havent yet seen.. example of it.
