This question has probably been asked a million time, but here it comes
again. I want to learn the difference between the three type cast operators:
static_cast, reinterpret_cast, dynamic_cast. A good way to do this is by
example. So I will give an example and please tell me what you think:
I have a base
class A
with a virtual destructor, and a
class B
that is it inherits publicly from A and defines som extra stuff.

Hi,
I'm having a little bit of trouble regarding pointer casting in my program.
I don't understand why the following two cases produce different results.
Case 1:

pInterface->Method();
Case 2:

I have been reading about the practise of casting values to unsigned
char while using the <ctype.h> functions. For example,
c = toupper ((unsigned char) c);
Now I understand that the standard says this about the <ctype.h>
functions:
"The header <ctype.h> declares several functions useful for classifying
and mapping characters.166) In all cases the argument is an int, the

Hi there,
Is there anyone that knows how to do the following?
I have a class A and a class B, that 100% inherits from class A (this means
that I don't have other code in class B, than the Inherit statement).

Hi all, I just discovered a rounding error that occurs in C#. I'm sure
this is an old issue, but it is new to me and resulted in a fair amount
of time trying to track down the issue.
Basically put the following code into your C# app:
float testFloat2 = (int) (4.2f * (float)100);
Console.Out.WriteLine("1: "+testFloat2);
and the result will be 419

Hi ,
I was going through peter van der linden's book Expert C programming,
in this book there is a section named "How and why to cast"
the author then says as follows
(float) 3 - it's a type conversion and the actual bits change.
if you say (float) 3.0 it is a type disambiguation,and the compiler
can plant the correct bits in the first place.some people say that

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
