QUESTION
I want to create a toString function for Tuples with a variadic amount of a specific type (arithmetic types for now).
Something like this
...ANSWER
Answered 2021-Jun-16 at 03:17You can check all the types are identical or not with the help of fold expression (since C++17).

QUESTION
I'm learning C++ and have come to a bit of a halt. I'm trying to iterate over a vector with a range-based for loop and update a property on each of the objects that belong to it. The loop is inside of an update function. The first time it fires, it works fine; I can see the property gets updated on each member of the vector. However, the next time the for loop is initiated, it's still updating the original data, as if the previous run did not actually update the source values. Is my range declaration configured correctly? Pointers are still a bit of a mystery to me. In general I'd be very thankful for any help!
...ANSWER
Answered 2021-Jun-15 at 23:19Vector3 position = point.position;
makes a copy of point.position
. The following code then updates this copy, which in turn is thrown away when it goes out of scope at the end of the if
statement.
The solution is simple enough - use a reference instead: Vector3 &position = point.position;
. The rest of the code can be left as-is.
QUESTION
so I'm struggling with these things:
I have method that returns istream input and takes istream input as a parameter, sends values to vector and stores them in it. Now, when I've entered 1 value, I'm trying to make a check if vector already contains that value, here is my code to understand it better:

QUESTION
I have a dataframe where one column is ; separated strings, e.g. "str1;str2;str3;str4", I also have another static list "strx;stry;strz", the goal is to split the column string value and check if the split array has any intersection with the static list, and keep that row
I tried
...ANSWER
Answered 2021-Jun-15 at 20:34It seems you're mixing up Spark's split
method for Columns with Scala's split
for Strings. Please see example below for how the two different split
methods are used. Method array_intersect
is for intersecting the split Array column with the split element-filter string.

I would like to prevent a turtle from visiting a patch it has visited before. I'm developing the code, but this error appears: error: "a patch cannot access a variable of a turtle without specifying which turtle".
I'm pretty sure it's another syntax error. But, I am not able to find this error. I tried to simplify the code to make it easier for you guys to help me. Any kind of help is welcome.

QUESTION
I wrote a discord bot. "o" is first letter of play. "atla" is skip. When I wrote -o MUSIC_NAME, music is adding queue and starting to play. And when I write again, just adding queue. Everything is okay still here. When I wrote -atla. It's also working perfectly. But when I allow to changing auto music itself, it's changing music automatically. But problem is here. The end of the last music not working else if (list.length === 0) block in endHandler function. How can I fix that? Thanks for your attention.
...ANSWER
Answered 2021-Jun-15 at 15:41I'm not familiar with Discord bots but I don't think your endHandler
will ever run the else if
part the way it is because your code is always creating a new dispatcher
when it plays the next song, but never sets up a finish
handler for it.
