Alright, I took your advice and took out my clears.
I saw what you ment when I looked at other command line programs
and you were right. I don't know why I wanted them in there in the first
place.

Two things.

That loop above works very well for filtering out letters from the input.
Only problem is I don't understand it. Any chance you can explain to me
why it works?

Second, I am at a lost. I'm trying to make it so when you give the program
a path, it counts the files in the directory to see how many there are.
I can't find out how to do this with c++. Can someone help me with that
please.

I appreciate everyone's help and I'm learning a lot this is great.

Thanks,

nomb

i have used ftw() to traverse a dir structure. you could use it to count, im sure there is probably a better idea though.

the loop only accepts valid input because it uses the cin extraction operator. the extract op knows that you are extracting into an int, so it only accepts an int. if it fails, the clear() call resets the stream error flags so that you can try again.

I see that makes sense. I can't find ftw(). Also I can't find any way to list the files. Well actually, I just want to count the files but if I can figure out how to list them I can count them. I found something called boost but I have no idea how to use it. :'( Can anyone help me?
