This seems like it ought to work, according to the
description of reduce(), but it doesn't. Is this
a bug, or am I missing something?

I thought it might be useful to put the recent lambda threads into
perspective a bit. I was wondering what lambda gets used for in "real"
code, so I grepped my Python Lib directory. Here are some of the ones I
looked, classified by how I would rewrite them (if I could):
* Rewritable as def statements (<name> = lambda <args>: <expr> usage)
These are lambdas used when a lambda wasn't needed -- an anonymous
function was created with...

Does it mean "(sizeof(int))* (p)" or "sizeof( (int)(*p) )" ?
According to my analysis, operator sizeof, (type) and * have the same
precedence, and they combine from right to left. Then this expression should
equal to "sizeof( (int)(*p) )", but the compiler does NOT think so. Why?
Can anyone help me? Thanks.
Best regards.

Can we consider () unary operator when calling a function, in exps eq.
f(), ( 1 + 2). But when we call function f( 10 ) it is a binary
operator. Even if we pass f( 10, 20) as we are using , operator there
one operand will be there for ()?
And Unary operators like !, +, -, ~, ... are said to be having
associativity right to left which means that we can write, (but not
allowed)
1. 2!
2. !2

I know the basic definition of a sequence point (point where all side
effects guaranteed to be finished), but I am confused about this
statement:
"Between the previous and next sequence point an object shall have its
stored value modified at most once by the evaluation of an expression.
Furthermore, the prior value shall be accessed only to determine the
value to be stored."
Can someone give me examples of expressions that "barely"...

Hi, in TC++PL3 on page 665, regarding valarray member functions, it is
mentioned:
"valarray operator-() const; // result= -v for every element
// similarly: +, ~, !"
I checked the web and could not find anything that explains the need of
this "operator+".

Hi,
In the following code, the 'copy' member function works. But the '='
operator does not work. Can somebody let me know why a member function
is different from an operator.
Thanks,

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,...
