Q: Need to know what is correct for my first vm and what I should change when I write my next

Joe DimagioI wrote my first virtual machine recently, and I need to know what I should change in my next vm to make it an actual vm. I created this one as more of just an interpreter with a instruction set you would see in assembly. I did not create this using many things a vm should have, and I put it toge...

You'll have to take the time to understand the advice you have been given above. Often it is good to take a break and come back fresh to think about your problems. I also recommend that you paste your code into shellcheck.net and fix any errors or warnings. You can also delete your question here and repost it to Code Review , which is the proper forum for requests for help like this. Please read Help On-topic and Help How-to-ask before posting more Qs here. Good luck! — shellter 25 secs ago

Yeah, you will have to type std:: in front of the standard library functions if you remove using namespace std; but it's worth it and you'll have to get used to it eventually anyway. using namespace std; will not pass through a real code review - especially if it's in a header file. If you've used the GCD function I suggested, at least that part should be ok. — Ted Lyngmo 28 secs ago

Coffee without close votes in the queue, what am I to do?

I believe you should put this code to code review since there are a lot of improvements that makes this a whole new project rather than minor fixes. Since you are creating sheets on the fly, you should create a json array and use as keys the sheet objects and as values an array of the elements you want to append. In this way, you will fill in this json array and then use it to setValues() in every sheet and you will get rid of all the appendRows()s you are using. — Marios 1 min ago

Q: Syntax highlighting for C++ for variables assigned with `=` vs `()` for C++

Aryan ParekhHere is the example int a = 5; int c(5); I hope the syntax highlighting works for you, if not then the way a and c are highlighted is different, shouldn't they be highlighted the same way? c has the same highlighting as a function would have (bright orange)whereas a has no highlight.
