I've written an interface and implementation file along with a client
source file that allows the use of an overloaded subtraction operator.
However, when
using the program, I'm running into a memory problem that I'm not
readily seeing that lies within the overloaded operator - I think
pertaining to the temporary class object that is created...

Hi,
Are 1 through 4 defined behaviors in C?
unsigned short i;
unsigned long li; /* 32-bit wide */
1. i = 65535 + 3;
2. i = 1 - 3;
3. li = (unsigned long)0xFFFFFFFF + 3;
4. li = 1 - 3;

hi
i have a problem with integer subtraction in C.
printf("%d", c < (a - b));
a is got from a #define and is 0x80000000 and b is got from input and
is also 0x80000000.
c is ffffffff (-1).
Now, this should print 1 (true) but it prints 0!

Can anyone illustrate this with an example:

Hi,
In my previous post I asked if sizeof may be implemented as a
function. Somebody pointed a link that says that sizeof may calculated
as follows with a warning that it is not guaranteed to work on all
implementation.
size_t size_obj = (char*)(&obj + 1) - (char*)(&obj);
I wanted to find out on which implementation this would fail....

Is there a php function to determine the difference between dates.
I'd like to take a birthdate and then determine how old a person is
dynamically and simply return the age in years.
TIA

Hey, I have a bit of code that died on a domain error when doing an
arcsin, and apparently it's because floating point subtraction is
having problems. I know about the impossibility of storing floating
point numbers precisely, but I was under the impression that the
standard used for that last digit would prevent subtraction errors
from...

Hi folks,
when subtracting 2 timestamps from each other the result is duration.
() But in DB2 the format is a bit funny:
lets say we have 59,5 seconds. If we have one second more, the result
is: 100,5. This mechanism works for seconds, minutes, hours, days.
months and years.
That would be OK if we always have the same number of days a month...

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.
This is as boiled down as I can make it. ...

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.
