Isn't that just a touch on the churlish side, Pete (albeit correct!)?

For the record, I thought Mark's reply was superb.

A very kind remark, Richard. Thank you. I've also added a splendid
adjective to my vocabulary ;)

Truthfully, though, I was ignorant of EXIT_SUCCESS and EXIT_FAILURE, so
thanks also to Pete for pointing this out.

Regards, Mark

Well, duh. His program invokes undefined behavior, or at least

You don't know that, since you haven't seen qfloat.h (it may be
perfectly compliant).


Imprimis, he didn't show us his qfloat.h, so the program _as posted_
invokes non-defined, IIRC undefined, behaviour.
Secundis, you can't definedly use <> with your own headers; only the
Standard headers are guaranteed to be useable that way. "qfloat.h" is
also not quite guaranteed to be found, but there are more requirements
for the search in that case.

in K&R Chapter 6.3 it mentions two methods to calculate NKEYS. and points out the first one which is to terminate the list of initializers with a null pointer, then loop along keytab until the end is found is less efficient than using sizeof operator , since size of the array is completely determined at compile time. i don't quite understand this. Could anyone explain to me in detail ?

I have 3 fields in an aspx page. The 3. field should be the sum of field A and field B I use OnTextChanged to calculate the sum in field3.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
