QUESTION
Please excuse the use of var, it is part of the challenge and is intended to help me learn about closure. Currently, the code gives all 100 h3's the same sentence. I've tried moving the randomName, randomWeapon, and randomLocation variables into the addEvent function. When I do this I assign the same h3 a new sentence on every click. I'm guessing I need to use .call or .apply, but I am new to functions, and internet tutorials just aren't getting me there.
...ANSWER
Answered 2021-Jun-11 at 20:59The problem is that your addEvent
bind the click
hander on the body
and not on the h3
. And the second is that you do e.preventDefault
when you have not defined e
(you should set it on the click
handler,not the addEvent
function) which causes an error and stops the execution.
If you had fixed the e
issue, you would see that when you click on an h3
you get all 100 alerts.
Try changing
QUESTION
By array intersection I mean, the inventory has a lot more elements than each document ingredients array, and the result I want to get from the query is all documents which all array elements are contained within the inventory. $all will get me zero results since the inventory has more elements than can be found in ingredients even if all ingredients are found within the inventory,
I have thousands of docs that have an array field of strings

QUESTION
I'm trying to solve a task that's a bit too much for me. The idea is to have a simple RPG game with the parent class (AllPlayers) and a subclass PlayerOne. I'm struggling with the calling of the player profession and his inventory system. I need to print how many coins the player has in its pocket, too.
MAIN:
...ANSWER
Answered 2021-Mar-30 at 07:39call the profession in the main?
Well, you already have the type declaration PlayerOne player;
so just call player.getProfessions()
and use the array.
call the inventory in the main?
Just the same: player.getInventory()
.
However, note that your design is somewhat flawed (although since you're a beginner don't bother too much). The class name PlayerOne
indicates any other player (e.g. PlayerTwo
) would be different, but that's probably not the case. Also, AllPlayers
doesn't actually indicate a class, but it looks more like a collection.
You might think about changing your class names, e.g. assuming AllPlayers
will be used for NPCs as well, you could name it Character
while the class for players is called Player
. Doing this you could have multiple players if needed: Player playerOne
, Player playerTwo
etc.

QUESTION
I am creating a function that checks the user's username and password. When I enter the username and password correctly, the program outputs the correct string. Then, when I enter the incorrect username OR password, the correct while loop is output. However, when I try to enter the correct username after the while loop, I get an infinite loop of my while loop contents.
What is causing this infinite loop when entering the username a second time?
Here is the function I am working on:
...ANSWER
Answered 2021-Feb-17 at 05:24You need to ignore the rest of the current line after the usage of std::cin
, up to EOF
or '\n'
– so that the earlier input is cleared. This problem can be easily fixed by adding two lines:

QUESTION
I have a text file with many rows that generally follow the patterns shown below and I'd like to extract the segments numbered 1-4 in the image below. I cannot do it with Excel because the punctuation is not sufficiently consistent so I'd like to use RegEx.
I am looking for 4 distinct RegEx expressions, corresponding to the 4 items.
What I have so far:
(.+?(?=/))
gets me everything up to the/
but I can't figure out how to split it in the Yellow and Cyan sections(?<=\/\s)(.*)
gets me everything after the/
but includes the Mintmark portion
Here is a good sample of the file contents:

Answered 2021-Jan-26 at 20:49You could use a single pattern with 4 capturing groups.

Answered 2021-Jan-08 at 17:36This error message usually means that you're trying to sign in to a different project than what the token was minted for. So you might want to check if you have the info.plist for the correct project, and that you're set up you OAuth sign in against that same project.

In R, I need to put the results of a correlation analysis between two variables in a table.csv file. The original dataframe is made up of three columns: the first column (group) contains the group to which the observations belongs, while the other two columns (var1 and var2) contains the values of the two variables.
...ANSWER
Answered 2020-Dec-26 at 13:39We can use lapply()
to extract values from the output objects, convert them to data frames, and write the combined data frame to a csv file.
