1)
is C++ smart enough to automatically use "bits" for bool or will
a bool have the size of a charcter (byte).
2) The index of a vector is it an integer (4 byte) or a "long long"
with 8 bytes or something else?
I ask because I want to use
vector<bool> with a few billion entries exceeding the int32 range for
indexing and I want to use as few memory as possible for the whole

Why was the bool type introduced into c++?
What does it provide that int does not and are the two entirely
interchangable in conditional expressions?
Thanks

I'm trying to learn the very basics of using an unmanaged C++ DLL from C#.
This morning I thought I was getting somewhere, successfully getting back
the correct answers to a C++ " int SumArray(int ray, int count)"
Now I'm having problems with C++ "return(false)" being True in C#.
Here is the C# code.

If I wanted a super-efficient algorithm for counting the amount of 6's in
an array, (given the address of the first element and the amount of
elements), I might start off with:
#include <cstddef>
unsigned AmountSixes( const int *p, std::size_t const len )
{
unsigned amount = 0;

First of all: I love C and think that it's beautiful. However, there is
at least one MAJOR flaw: the lack of a boolean type.
OK. Some of you might refer to C99 and its _Bool (what's up with the
uppercase 'B' anyway?) and the header you can include (apparently) to
get a real "bool". This isn't my point, however -- it should have been
there from the beginning.
Char is a small int. We all know that. However, "char some_bool = 0;"

I am using mikroC to program some microcontroller code in C. However I
have come across of potential problem of bool type not being supported
from the compiler complaint on how I declared type bool variable. From
a forum thread that I've pulled out from mikroBasic, I realized that
bool type isn't fully supported. When programming in mikroC, I have
been getting an error message of "invalid expression" when I declared
a bool type variable,...

Hi there,
we have this C++ DLL we wrote some time ago to do some Win32 native
stuff for us.
The function we're calling in the DLL returns a boolean value (type
bool) indicating success of the operation.
We declare the import in C# like follows:

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
Here is the code in...

Overview:
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,...
