I wanted to know how i can make the title that is
displayed in a tabpage bold when it is selected.
I have 4 tabpages and i want the user to know more

Hello, all,
This is probably not so much related to C++ (Sorry in advance). But
I did get this question during a C++ job interview.
You are asked to design some data structure and algorith for the
following function:
List getNames ( List nameList, String prefix );
What it does is: given a name list and a prefix, return all the
names in the name list that start with prefix.

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:

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,...
