Hi there.
Because of the lack of a Union query in MySQL 3 I have decided to take the
approach where I populate two arrays with values from similar tables in DB.
In this case they are `courses` and `lessons`
Lets say Courses has fields
CourseID(PK), Date, Name, RunBy, Status
The lessons table is related to the Courses table in that a...

Dear ALL
As we know that when we declare the union then we have the size of the
union which is the size of the highest data type as in the below case
the
size should be 4 (For my case and compiler), and it is,
what I conclude from the below code

Hi,
I have found a piece of code which declares union like this:
union vector_s {
struct {float x,y,z};
float m;
} v;
there is unnamed structure m ( matrix 1x3 ) which has same offset as
x, so they are aligned properly. The problem I have is, whether I can
safely write data to, lets say, v.m and read same data from v.z?

I hate using struct / union with dot between two words. How can I use
one word instead of two words because I want the source code look reading
clear. three variables are shared inside one variable. I manipulate to
change 8-bit data before it causes to change 16-bit data and 32-bit data.
For example.

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. ...

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.
