DragonBall | DragonBallZ Game In React Native

I just found something "kinda strange" about PHP 7.4 and I am not sure if it is just me missing something or maybe if it is an actual bug. Mostly I am interested in your opinion/confirmation.

So in PHP, you can iterate over objects properties like this:

For a classification project I need the raw html content of roughly 1000 websites. I only need the landing page and not more, so the crawler does not have to follow links! I want to use scrapy for it but I can't get the code together. Because I read in the documentation that JSON Files are first stored in memory and then saved (which can cause Problems when crawling a large number of pages) I want to save the file in the '.js' format. I use the Anaconda promt to execute my code.

I want the resulting file to have two columns, one with the domainname, and the second with the raw_html content on every site

If I have a string as follows: "Dragonballs are cool."

but I want to change the spaces into multiple lines: "---"

So this would be the end result: Dragonballs---are---cool.

How would i do it? Is a loop necessary (I know how to replace single characters with another single character), or is there another way to it?

How can I remove items from a list but keep its original order? Using remove() seems to mess the order up.

Let's say for example a list like this:

If I have for example a line of string like this:

I'm making this example up for the sake of explaining the problem. If I have a .csv file as follows:

I am having an issue when I try to compile this solution.
I am fairly new to c++, but I have been teaching myself with practicing things. Please critique!

I am getting a huge list of errors, but I have spent hours searching the internet to find what I am missing, but I can't seem to cypher the error message.

The biggest error seems to say that it doesn't recognize my cin>> command

I wonder if it is possible to place an if statement inside each case, and may be easier to read, but I keep thinking that isn't legal.

I have an array of objects which holds data, which I output to the DOM using map. Each item in the list, has a @click event listener. When you click on one of the items, I want it to be highlighted by way of adding a css class, for example ‘hover’. So basically it should work like a menu system. When you click on an item, that item is highlighted and the others should not be highlighted and vice versa.

The way i have it set up right now, all of the items in the list get highlighted, which is not the logic i’m trying to do. I have used console.log, to display which item has been clicked. However, I still have not figured out, how to make that selected item, the one thats highlighted instead of the whole list?
