In math this expression:
(a < b) && (b < c)

different for the same values of a, b and c?

be called when the C/C++ program creates output on stdout.

Hi
For this code,
int getopt (int argc, char *const argv, const char *opts)
what does the "char *const argv" mean? Does it equal to "char **const
argv"?
Or "char *const *argv"? Which is the const?
Thanks

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
