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;

When I add an unsigned long long and an int, what type do each of the
values get promoted to before the addition is performed? What is the
type of the resulting expression? What occurs if the addition overflows
or underflows?
Thanks,

Using reflection, I am iterating through an array of FieldInfo objects and
wish to determine whether any given field represents a signed or an unsigned
variable (makes a difference in terms of how I parse some data from a raw
byte stream).
Is there anyway to determine whether a particular field is signed or
unsigned either from a FieldInfo object or else from a Type object stored in
fieldInfo.FieldType property?
Thank you very much...

Hi everybody,
please, can someone explain me this behaviour.
I have the following piece of code:
long long ll;
unsigned int i = 2;

I have defined a number of unsigned integer types as follows:
typedef unsigned char uint8;
typedef unsigned short uint16;
typedef unsigned int uint32;
typedfe long long uint64;
Is it necessary to explicitly cast from one type of unsigned integer type to
another even though they do so implicitly?

Hi,
I encountered a problem involving storage of unsigned long long. The
requirement of incoming data field is an unsigned 64-bit integer, but
on our system, due to lack of support of 64-bit integer from Oralce
pro-C(it only supports 32-bit integer). We have to find a way to get
around it. I am wondering whether there is other way to store big int
in kind of 8-byte raw data and later convert it to 64-bit integer. Is
the raw data has to...

Hello,
Is it safe to assume a size_t is an unsigned long? (is it forced by
the standard?)
Thank you,

Hi All,
I am trying to undestand "Type Conversions" from K&R book.I am not
able to understand the
bellow mentioned text
"Conversion rules are more complicated when unsigned operands are
involved. The problem
is that comparisons between signed and unsigned values are machine-
dependent, because
they depend on the sizes of the various integer types. For example,
suppose that int is 16 bits

Hello
I am looking for some effecient way to convert a 32 bit unsigned
integer to a 16 bit signed integer. All I want is the lower 16 bits
of the 32 bit unsigned integer , with bit 15 (0..15) to used as the
sign bit for the 16 bit signed integer. Any ideas/help greatly
appreciated.
Thanks.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
