I am writing a generic C++14 multi dimensional array for computational science purpose.
The "features" so far for the class tries to :
store multi-dimensional grid values into a flatten array
provide grid values access and flat index access from multi dim coordinates with O(1) average complexit...
The first thing I've noticed is that you return 2 different things:
The data that the user wanted;
The error information.
Now, how will you distinguish between an errored query and a successful one? You can't! And that makes angels angry and cry.
Return null in case of error.
Your variabl...
I don't like the idea of using an all-in-one struct. You will have to do more maintenance: every time you create a function that returns different values, you have to create a new struct.
Further, I think the struct return value will confuse the user. Everyone is familiar with the basic types, s...
My answer.
It's mostly redundant with the previous (better) answer by @Joey. It got my vote.
It's still got a twist of it's own, so here goes.
It's an annotated revision. It's still O(n) -- don't see how it could NOT be.
It's more idiomatic and less redundant. It's not compiled or tested.

Disclaimer: I own Rubberduck's GitHub repository, and I'm one of the devs involved in the project.
Rubberduck is under active development. It's much more than a unit testing tool for VBA though, but it works pretty well and lets you write VBA unit tests pretty much without any boilerplate:

Rather than having lot's of prints, you can do something like this:
print(
"This will",
"be printed",
"on separate",
"lines.",
sep="\n"
)
I'm not a huge fan of your naming too. Some of the names, like runsys could really use some underscores, like this: run_sys.
I also don...
After our recent election, I got elected a moderator here on Code Review (Thanks you, community members!). One of the first things I missed among the moderator tools was desktop notfiications for when there were any flags.
As no current tool existed, I figured that I just have to create one...

These flags do count towards the badges when appropriately dismissed as helpful, but moderators aren't eligible to receive either Deputy or Marshal badges according to Geoff Dalgas:
The Deputy and Marshal badges are only granted to registered users - not moderators.
I've written the following code to print all permutations. For example:
[1,2,3] have the following permutations: [1,2,3], [1,3,2], [2,1,3],
[2,3,1], [3,1,2], and [3,2,1].

I really got the idea from Is it possible to go on a tour of the Stack Exchange headquarters? I live closer to Denver, is there much of an office there? What about your London offices?
Can we have a sneak peak at the other offices as well?
