Point taken, except that I use Arduino & don't consider myself a complete idiot.
When using structures that have been in common use in other languages for several decades it should normally be sufficient to look up just the syntax. The documentation and the Arduino Cookbook (700 pages) are very well written; all I was saying is that it would help if the little warnings about the differences between Arduino and pure C++ could be extended to include other languages a user is likely to have encountered.
If you've had the misfortune to write XL VBA macros during the day for your employer, a little reminder that C++ "for" loops don't have the equivalent to "to" in them would make life easier when you switch to Arduino and a different reference book back at home.
