No, you aren't na idiot. You just don't how to do it, nobody knows
everything.

I think you can use strlen(); it returns an integer with the lenght of the
variable (0 if it's blank).

Don't worry, I learned this function some weeks ago...

Happy new year, bye bye.

I might be an idiot...

I am trying to do a simple check to make sure a string contains 
at least an alphanumeric character before I print the string.  
How can I do this?
