Write a while loop inside for loop?
I'm taking a unix class and need to countdown to 0 from whatever number the user inputs. I know how to do this with a while or until loop but using the for loop is throwing me off....

I know I can use an if-then statement in my for loop but can I include a while loop in my for loop?

There's a special forum section for "homework" style stuff.

When you do move the post there, make sure you put in all the required info and you probably need to provide a bit more detail on your request (e.g. what language you are writing the program in).

Yes, you can. Smilie

For any further/other questions, please use the homework section of the forum, following the mandatory template, as cjcox already stated.
