            Calculating the number of elements in an array using pointer arithmetic
            Asked 2021-Dec-11 at 23:40

            I have come across a piece of example code that uses pointers and a simple subtraction to calculate the number of items in an array using C++.

            I have run the code and it works but when I do the math on paper I get a different answer.

            There explanation does not really show why this works and I was hoping someone could explain this too me.

            You forgot a small detail of how pointer addition or subtraction works. Let's start with a simple example.

            How to select a colored item from a bulleted list
            Asked 2021-Dec-04 at 12:27

            Here is my menu

            If I click on Market for example, the background color must be in green.

            I don't understand why the Currency and the Portfolio are in green?

            In fact, the green background appears depending on the menu selected.

            How can I solve this problem, please?

            I think that the problem is perhaps here

            Asked 2021-Dec-03 at 22:32

            To keep it simple, I created a menu and all of my bullet lists are stored in an array.

            My problem is that when I run the loop it shows me 2 times, the same values ?? I do not understand why?

            I think that the problem is in the HTML file?

            You may use icons as font with adding to your project instead of using them separated images. I think best option for angular project is material icons.

            Why is my title of my pages not positioned correctly?
            Asked 2021-Nov-29 at 10:43

            I have a component named admin.component, in this component, I have a menu and a header.

            In fact, when I create a new page, for example: the currency page.

            The title is at the bottom of the la page, I don't understand why?

            Normally, the title must be at the top...

            I think that the component admin.component.html isnt't correct?

            Maybe and Either monads, short-circuiting, and performance
            Asked 2020-Sep-17 at 19:32

            Functional Programming in C++, at page 214, with reference to an expected monad which is the same as Haskell's Either, reads

            [...] as soon as any of the functions you're binding to returns an error, the execution will stop and return that error to the caller.

            Then, in a caption just below, it reads

            If you call mbind [equivalent to Haskell's >>=] on an expected that contains an error,, mbind won't even invoke the transformation function; it will just forward that error to the result.

            which seems to "adjust" what was written earlier. (I'm pretty sure that either LYAH or RWH underlines somewhere that there's no short-circuiting; if you remember where, please, remind me about it.)

            Indeed, my understanding, from Haskell, is that in a chain of monadic bindings, all of the bindings happen for real; then what they do with the function passed to them as a second argument, is up to the specific monad.

            In the case of Maybe and Either, when the bindings are passed a Nothing or Left x argument, then the second argument is ignored.

            Still, in this specific two cases, I wonder if there's a performance penalty in doing something like this

            Template specialization and references
            Asked 2020-Sep-10 at 06:36

            In Functional programming in C++, chapter 11 deals with some basic template meta programming.

            In this context, the author shows this implementation of remove_reference/remove_reference_t, which are essentially the same as those described on cppreference.



            Answered 2020-Sep-08 at 22:27

            only the general (or primary? What is the correcto word here?) template

            The technical term used by the C++ Standard is "primary class template". It will also be the most general class template, compared to its partial specializations and explicit specializations. So that could also be a reasonable thing to call it, given enough context.

            The "reference collapsing rule" is found in [dcl.ref]/6 and applies mainly when determining the meaning of combining a specific type name which aliases a reference type with a & or && token which would normally form a reference to the type name's type. Deducing template arguments for a template parameter of the form T& or T&& is sort of the reverse of that. Although it's helpful to think of template argument deduction as "find the template arguments so that the resulting types match up", the technical details of template argument deduction are much more specific; [temp.deduct] is several pages of rules for exactly how this deduction proceeds, and there are additional relevant rules in other sections. The detail is needed so compilers agree on cases when there could otherwise be more than one "correct" answer, and so that compilers aren't required to deal with some of the more difficult cases.

            In particular, when matching a dependent type P with a known type A, by the list of deducible types in [temp.deduct.type]/8, deduction can occur if both P and A have the form T& or if both have the form T&&. When attempting argument deduction for the partial specialization remove_reference to determine the definition of remove_reference, P is T&& and A is int&, so they do not share one of these forms.

            The template argument deduction rules do not have a general allowance for deducing arguments from a reverse of the reference collapsing rule. But they do have a limited allowance which is related for certain cases: Per [temp.deduct.call]/3, if T is a template type parameter, but not a parameter for a class template, then the type T&& is a forwarding reference. When comparing types for argument deduction, if P=T&& is a forwarding reference type and A is an lvalue reference type, then the template type parameter T can be deduced as the lvalue reference type A, only if A is the type of an lvalue function argument expression ([temp.deduct.call]/3 again) or sometimes if P and A are being compared because they represent function parameter types within two compared function types ([temp.deduct.type]/10).

            Similarly, when ["]calling["] remove_reference_t, can't the first specialization's T& match int&& if T is substituted for T&?

            In this case, there's no possible way that the partial specialization remove_reference can match remove_reference. Even if the process of template argument deduction allowed finding a potential answer for this case, there is no possible type T such that T& is the same as int&&.
