QUESTION
There are a number of different ways, that make a type/class usable in a ranged for loop. An overview is for example given on cppreference:
range-expression
is evaluated to determine the sequence or range to iterate. Each element of the sequence, in turn, is dereferenced and is used to initialize the variable with the type and name given in range-declaration.
begin_expr
andend_expr
are defined as follows:
- If
range-expression
is an expression of array type, thenbegin_expr
is__range
andend_expr
is (__range
+__bound
), where__bound
is the number of elements in the array (if the array has unknown size or is of an incomplete type, the program is ill-formed)- If
range-expression
is an expression of a class typeC
that has both a member namedbegin
and a member namedend
(regardless of the type or accessibility of such member), thenbegin_expr
is__range.begin()
andend_expr
is__range.end()
- Otherwise,
begin_expr
isbegin(__range)
andend_expr
isend(__range)
, which are found via argument-dependent lookup (non-ADL lookup is not performed).
If I want to use a ranged for loop say in a function template, I want to constrain the type to be usable in a ranged for loop, to trigger a compiler error with a nice "constraint not satisfied" message. Consider the following example:
...ANSWER
Answered 2022-Apr-14 at 09:51It seems like what you need is std::ranges::range
which requires the expressions ranges::begin(t)
and ranges::end(t)
to be well-formed.
Where ranges::begin
is defined in [range.access.begin]:
The name
ranges::begin
denotes a customization point object. Given a subexpressionE
with typeT
, let t be an lvalue that denotes the reified object forE
. Then:
If
E
is an rvalue andenable_borrowed_range>
isfalse
,ranges::begin(E)
is ill-formed.Otherwise, if
T
is an array type andremove_all_extents_t
is an incomplete type,ranges::begin(E)
is ill-formed with no diagnostic required.Otherwise, if T is an array type,
ranges::begin(E)
is expression-equivalent tot + 0
.Otherwise, if
auto(t.begin())
is a valid expression whose type modelsinput_or_output_iterator
,ranges::begin(E)
is expression-equivalent toauto(t.begin())
.Otherwise, if
T
is a class or enumeration type andauto(begin(t))
is a valid expression whose type modelsinput_or_output_iterator
with overload resolution performed in a context in which unqualified lookup forbegin
finds only the declarations
QUESTION
Why does this happen in Python?
float('inf') == float('inf')
returnsTrue
,float('inf') + float('inf') == float('inf')
returnsTrue
,float('inf') * float('inf') == float('inf')
returnsTrue
,float('inf') - float('inf') == float('inf')
returnsFalse
,float('inf') / float('inf') == float('inf')
returnsFalse
.
My best guess, if I think about limits, is related with the result of this operation:
limx→+∞(f(x) ▢ g(x)) where limx→+∞ f(x) = +∞ and limx→+∞ g(x) = +∞, which returns +∞ if ▢ is + or *, but it is not defined (it could return every value) if ▢ is - or /.
I am very puzzled, though.

I am wondering how to solve this problem with basic Python (no libraries to be used): How to calculate when one's 10000 day after their birthday will be (/would be).

QUESTION
I have the following instruction: mov r1, r7
in my assembly code but after looking into disassembly, I've found that actual generated code was adds r1, r7, #0
I checked with ARMv6-M Architecture Reference Manual and I found out that there's MOVS ,
instruction (A6.7.40) which is different from ADDS
.
While that's not a big issue, I'm still puzzled why assembler replaces code that I wrote by different op-codes. According to the book that I'm reading, all non-jump instructions take 1 cycle (and I'd prefer for assembler to be dumb rather than trying to optimize something for me).
I'm using Raspberry Pi Pico SDK which uses GNU Assembler, AFAIK.

I am attempting to solve a coding challenge however my solution is not very performant, I'm looking for advice or suggestions on how I can improve my algorithm.
The puzzle is as follows:
You are given a grid of cells that represents an orchard, each cell can be either an empty spot (0) or a fruit tree (1). A farmer wishes to know how many empty spots there are within the orchard that are within k distance from all fruit trees.
Distance is counted using taxicab geometry, for example:
...ANSWER
Answered 2021-Sep-07 at 01:11This wouldn't be easy to implement but could be sublinear for many cases, and at most linear. Consider representing the perimeter of each tree as four corners (they mark a square rotated 45 degrees). For each tree compute it's perimeter intersection with the current intersection. The difficulty comes with managing the corners of the intersection, which could include more than one point because of the diagonal alignments. Run inside the final intersection to count how many empty spots are within it.

QUESTION
An old code base I'm refactoring has a rather unorthodox way to access n dimensional vectors by overloading the ()
operator instead of the []
operator.
To illustrate, suppose Vec is a class that overloads both operators for indexing purpose of an internal list of doubles.
...ANSWER
Answered 2022-Feb-04 at 15:52One "problem" with []
is when you have multiple dimensions. With an array you can do arr[val1][val2]
, and arr[val1]
will give you an array you can index with [val2]
. With a class type this isn't as simple. There is no [][]
operator so the [val1]
needs to return an object that [val2]
can be applied to. This means you need to create another type and provide all the functionality you want. With ()
, you can do data(val1, val2)
and no intermediate object is needed.

...ANSWER
Answered 2022-Jan-29 at 13:14It doesn't matter that i
is guaranteed to be evaluated only at compile-time when its value is known in an abstract sense.
It also doesn't matter whether the function is consteval
or constexpr
or none of these.
The language is still statically typed and nth_type_t;
must in any given instantiation of the function refer to exactly one type. If i
can change in the for
loop, that is not possible to guarantee.
The language requires that the expression i
when used as template argument is by itself a constant expression, independently of whether the whole function body can only be evaluated as part of a larger constant expression. But i
is neither declared constexpr
, nor declared const
with constant initializer.
