interesting question about tree

[compboy]

Hi can anyone print a binary tree in the way that it will look like a
tree?

so it will be like this:

50
/ \
30 70
/ \ \
20 35 100

can we do this in c without using gui as we can do this in java by
using gui?

thanks

I'm sure someone can.

Yes, definitelly possible using just plain <stdio.h> functionality.
can we do this in c without using gui as we can do this in java by
using gui?

And your C question was (asking for someone to do it all for you does
not count)?

Are you sure we can do this by just using plain <stdio.h>?
How do you do that then?
is it by pushing all the output to a stack or a queue and use it later
on?
Does anyone have an idea to help me to solve this problem?

Thanks.

It's not that difficult. Just build up a "canvas" in memory and
then output it line by line when you've finished. See, e.g. the
tree drawing program in GNU libavl.
