[Courses] C Programming For Absolute Beginners, Lesson 3: Else If, While, Operators

[Carla Schroder]

You are so right-- you can never have too many books :)

You might add line break or space after "Please enter how many books you 
have."

I got bit again by email inserting hard line breaks, so when you copy a 
program from email and get a wad of error messages check your line breaks. A 
nice syntax-highlighting text editor will show you right where this is, for 
example in Kate the first part of the line is colored, and then the text after 
the bogus line break is not colored.
