This week, we're updating our course layouts and descriptions. Presentation and materials always gently change over time, but just occasionally there's a need to make a step change to clear out some of the old and roll in the new. That's now happening - but over a long and complex site it's not instant and you'll see sections of the site changing up to and including 19th September.

Difference between a 'binary string" and a "string

Posted by neilvp (neilvp), 19 April 2007
I thought this sounded like a stupid question until I built up the courage to asked the 'professional programmers' that work where I do - and all I got was sheepish looks and mutterings of "need coffee".

The question being...
What is the difference between a 'binary string' and a 'string'?

At the fundamental level a string is composed of hex digits, which are made up of 1s and 0s which, by definition, is binary.

The supplementary question is then, when is it appropriate (or not ) to use binary scan, as opposed to scan?

Many thanks.

I seem to recall that non-binary strings do strange things with ASCII characters 128 to 159 -  but I have been looking for that and can't see it straight away. Could be another language.   Binary scan, etc, are used to get things like 4 byte integers out of variables, whereas scan is used to get number represented by strings of characters
