QUESTION
I need to assign 275 variables with the Double type. Is there a way I can paste word Double on all 275 lines at once? I have been pasting Double on each line and its tiring.(I also have to add the underscores to replace spaces in the variable identifiers. If anyone knows a shortcut for that let me know.)

Answered 2021-Jun-09 at 20:23You could use a tool like Notepad++ to make the changes you need.
I was able to convert the list you supplied by using "CTRL+H" to open the replace dialog, using regular expression mode, and replacing "\d+" with "Double":

This didn't work. It is clear that the compiler is optimising-out much of the code related to z completely! The code then fails to function properly (running far too fast), and the size of the compiled binary drops to about 50% or so.
Looking at https://gcc.godbolt.org/z/sKdz3h8oP, it seems like the loops are actually being performed, however, for whatever reason each z++, when using a global volatile z goes from:
QUESTION
I'm working on a signup form for users of my app. In the form I have two toggles. One is a slider and the other is a checkbox. I was able to get both of these toggles working fine and the view would update perfectly when I had all of the variables declared in the view.
I've refactored the project to move some functions and error checks into a ViewModel. Now my toggles are no longer updating the view, but the booleans they're toggling are changing values.
While I could go and cram everything back into the view, my preference is to figure out why this isn't working and what's the best way to approach these. I don't understand how an input field, for example, will update the View Model, but a toggle won't.
Here's my ViewModel:

QUESTION
I'm the kind of person who would systematically go through every single option available to toggle, and this time it's with clang-format in VSCode. I found this, which I'm assuming lists every single thing available to cram into a .clang-format file for VSCode to use. Unfortunately, VSCode seems to not recognize a handful of them:
BitFieldColonSpacingBreakBeforeConceptDeclarationsEmptyLineBeforeAccessModifierIndentAccessModifierIndentRequiresSortIncludesSpaceAroundPointerQualifiersSpaceBeforeCaseColon
Out of the handful of options that VSCode fails to load, only SortIncludes is recognized at all, but it only accepts a bool, not the options that the reference says are available. The rest of the options are outright not recognized:
ANSWER
Answered 2021-May-27 at 20:48Quickish answer: This is not a bug. At least some of those options (IndentAccessModifiers) are still in the "Work In Progress" clang 13. You would need to (download and) replace the underlying clang-format binary in order to use these new features.
For whatever reason, the clang-format page describing the various options defaults to showing you everything in version 13, but does not actually warn you that these are not official release versions. Nor does it at least tell you what version a feature was introduced. It's not until you do a little digging that you find out that the main documentation page is not what you want. The most recent VSCode uses version 11.1.0, and you can find the matching options here: ClangFormatStyleOptions version 11.1.0
FUTURE NOTE: This answer mostly only applies today May 27, 2021. This may not apply 6 years down the line and VS Code is now at version 22 of clang. That said, you may find this useful if you come across this same type of issue in version discrepancy.

QUESTION
I use android java,
I have two button, button A is run timer, it can change many vocabulary in 5 second,
the Button B is stop timer, when I press button A ,timer run fine, press button B is fine too.
But when I press button A->button B->button A, it will shut down,how can I slove this problem?
thanks.
this is my code:
ANSWER
Answered 2021-May-14 at 03:53You should have got NullPointerException in logcat.
You are setting timer = null; on ButtonB click. And when clicking on ButtonA, which invokes begin(), the app crashes, since timer is null!

QUESTION
I want to create a unique pointer using unique_ptr(new A) (not make_unique()).
The unique_ptr constructor is noexcept, however new may throw bad_alloc.
So my question is, whether I should expect an exception calling unique_ptr(new A) in case new fails or not?
I tried to check that and I'm getting 'abort' in the code below, whereas I expected to see "null" on the screen. So it seems, that in case new fails, unique_ptr will throw an exception.
Is that correct?
...ANSWER
Answered 2021-May-05 at 22:42So my question is, whether I should expect an exception calling
unique_ptr(new A)in casenewfails or not?
Yes. If new fails, it will throw a std::bad_alloc exception, and the std::unique_ptr object will not even be constructed at all.
I tried to check that and I'm getting 'abort' in the code below, whereas I expected to see
"null"on the screen. So it seems, that in casenewfails,unique_ptrwill throw an exception. Is that correct?
No. new is the one throwing the exception, not the std::unique_ptr constructor (which it can't anyway due to being noexcept, as you noted). Since new is being called outside of the constructor, the constructor being marked as noexcept is irrelevant.
If you want to avoid the std::bad_alloc exception being thrown, use the std::nothrow version of new, eg:

class A
{
char c; // c represents a value varying from 0 to 2^7-1 (I don't need a bigger range)
bool b; // b is a boolean value

QUESTION
I am trying to download several PDFs which are located in different hyperlinks in a single URL. I already asked a similar question here but this URL has a different structure. The URLs that contain the PDF's has the text "p_p_col_count%3D" which is included in the code, but for some reason it does not work.
There is another solution here, but here the web page has (in my opinion) a nice well structured HTML code, while the page that I am trying to scrape has 12 crammed lines of code. Moreover the PDF's in the solution web page can be downloaded in a single link while in my case you need to identify the proper URLs and then download them.
This is "my" code so far:
