When you want to store an integer in C++, you use an integral type, eg.
int main()
{
unsigned char amount_legs_dog = 4;
}
In writing portable C++ code, there should be only two factors that
influence which integral type you choose:
A) Signedness. Do you want only positive values? Or do you want both
positive and negative values?
B) The minimum range for that type as specified by the C++ Standard.
The minimum range for "short" and "int" are identical. The following
statement is always true on all implementations :
sizeof(short) <= sizeof(int)
As this is so, why would one ever use the type "int" at all? It seem to have
no merit whatsoever. I will always use "short" in its place.
Any thoughts on this?

Because it can be.
If it "can be", then why are you acting like "it is".
The same reason why fire-men are still on duty when
there's no fires around.
But if you'll notice, they don't act like there's a fire. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

The problem professor gave us is:
Write a program which reads two integer values. If the first is less
than the second, print the message "up". If the second is less than
the first, print the message "down" If the numbers are equal, print
the message "equal" If there is an error reading the data, print a
message containing the word "Error" and perform exit( 0 );
And this is what I wrote:

Well OK, an "easy" way would be instead of

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...

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,...
