Dear All,
A class having no member variables and only a method sizeof(object)
will return 1byte in ANSI and two bytes in Unicode.
I have the answer for this of how in works in ANSI. But I don't
know it returns two bytes in UniCode.
Please help...
For ANSI:
In ISO/ANSI C++ Standard, 5.3.3 § 1, it stays: "The sizeof operator
yields the number of bytes in the object representation of its

I have the problem with sizeof operator I also want to implement a
function that can return size of an object. My problem is as follows..
I have a Base class, say Base and there are many class derived from
it. At a particular point in my application I need the size of the
object pointed to by the base pointer. Eg

Hi, all.
What will we get from sizeof(a class without data members and virtual
functions)?
For example:
class abnormity {
public:
string name() { return "abnormity"; }

I feel dumb to ask because I bet this is a simple question...
Looking at the code below, can someone please explain why I get two
different values in my Marshal.SizeOf calls (see the commented lines)?
TIA!

Hi,
I have a class.
class C1
{
int i ;
char c ;
} ;
let me say the size of int is 4 and char is 1. Then if I say sizeof(C1)
it should be 5, why is it showing 8 ?

Hi,
Somebody recently asked me to implement the sizeof operator, i.e. to
write a function that accepts a parameter of any type, and without
using the sizeof operator, should be able to return the size occupied
by that datatype in memory in bytes. 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.
This is as boiled down as I can make it.
Here is my compilation command:
