At one time, mixing for x in file and readline was dangerous. For
example:
for line in file:
# read some lines from a file, then break
nextline = readline() # bad
would not do what a naive user might expect because the file iterator
buffered data and readline did not read from that buffer. Hence the call
to readline might unexpectedly skip some lines.

I have a function to copare two files. It will first copy the original file
form a different server to a local temp path and then compare that version to
a version that has been restored form tape. Once the compare is complete the
file that was copied to a temp location needs to be deleted. I am using the
method file.copy(sourcePath, tempPath, true) to copy the file and then
file.delete(tempPath) to delete the file. On some of the files...

Hey folks,
I am searching for a string (say "ABC") backwards in a file.
First I seek to the end.
Then I try to make a check like -
do {
file.clear ();
file.get(c);

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,...
