Time for another random syntax idea. . .
So, I was tinkering in the interactive interpreter, and came up with the
following one-size-fits-most default argument hack:
Py> x = 1
Py> def _build_used():
.... y = x + 1
.... return x, y

I want to check if the user enters alphabet or numbers only in the
text box. If the user enters non-alphabet or non-numbers, I should pop
up a message and doesn't allow the user to do that. I am using regular
expression to do the checking. But it seems it always return false.
What did I miss? please advise. thanks!!

Does anyone know if a easier way (built in function, or something) that
can verify that a string is an alphanumeric number? Here is what I am
doing now:
for(i=0; i < strlen(temp); i++){
if(!isalnum(temp)){
return 1
}
return 0;

I have developed a program that sends a command through the serial port
to our business system and then reads from the buffer looking for a
number. Everything worked great on my WinXP system, but when I tried
the program on the Win98 system it will be running on, I get the
following error:
Cast from string "2076719" to type 'Long' is not valid
I am not sure why I only get this error on the Win98 system or how to go
about correcting...

Hi, I'm a complete newbie to C, but I wanted to get started by writing
a few simple programs that print out strings.
1. The first thing I wanted to do was write a program that uses getchar
to read one letter at a time, and uses printf to print it out as
entered. I also wanted to make it terminate when the EOF character is
entered.

OK folks here is what I need help with. Lets assume I have a text field
that will contain AlphaNumeric data. There is no set pattern to the
field such that any given character can be either alpha or numeric. I
need a function that will return the requested 'part' of the contents of
the field. A 'part' would be defined as consecutive Alpha or Numeric
characters in the text field.
Examples:
Field Name = cFoo

Hello,
I am new to C and I am trying to write a few small applications to get
some hands-on practise! I am trying to write a random string
generator, based on a masked input. For example, given the string:
"AAANN" it would return a string containing 3 alphanumeric characters
followed by 3 digits. This part I have managed:)
I would now like to add some complexity to this, such as repetitions
and grouping. For example, I'd like to have...

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,...
