Aren't they (in this context) the same test? Re: Infile and loop problems 15 Years Ago by Jaxzen How could I set up a loop that would take an x number of values from the file? Would it just be while (infile) { if(n<25) if(n%2==0) add one to the even counter else if(n%2!=0) add one to the odd counter } ? And, what is the EOF?
