Q: The program returns and prints the bank account balance. But can this be better and more efficient

@SimonForsberg We absolutely need better tagging on meta, I agree with you on that.
@pacmaninbw @VisualMelon @dfhwze It's not something new. It happens when you link to the specific review of a post in the queue and the review has been completed. How many reviews it takes to complete an item depends a bit (on time passed and the votes cast), but everything is working as intended and it's nothing new.

@Mast An idea popped into my head about something similar to @DerKommissar's Vinder, but for tags instead. To have a "tag-review" system, where a question is shown and a question asked: "Should this post have tag XYZ?"
(I will not be doing any work on this, but I would happily use it if someone else implements it)
I'm voting to close this question as off-topic because this is probably a better fit for codereview.stackexchange.comDaveyDaveDave just now

@SimonForsberg Perhaps we should fix all current tags in use first, so they have a proper usage guide. But it could help in the clean-up after that, sure.

@DerKommissar I've professionally worked in C, C++, C#, PHP 5, JavaScript, HTML, CSS, Perl, C shell, Bash, VBA (excel), and once VB. I prefer to stay away from Web Development prefer internals.
Coming out of school I knew Fortran 66, Pascal, COBOL and at least one other language I can't remember any more.
Also 2 assemblers.
PDP-11 and Sparc
Oh, forgot SQL
Yep...very familiar. We did COBOL, Pascal and Fortran in school, as well as C/C++ and some other ones.
I have one client doing AT&T ASM right now...

@DerKommissar I thought they stopped teaching COBOL, it's almost a dead language.

@pacmaninbw Good choice. I love how easy it is to bring new features to users with web, but otherwise, it's more of a pain than desktop/backend.
@pacmaninbw I've been doing Web for 10 years, Desktop about 5 longer (yes, that means I've been doing this since I was 10). I don't mind either.
@Hosch250 I do a great job of making things work I'm not good at making things look good and the only thing I care to make look good is code.
I can usually make things look reasonably good, but it's harder than just code.
I usually do a couple mockups and ask for feedback.
@Hosch250 When a designer starts arguing about pixels it's too much for me.
I hate it when a ticket comes in because a button doesn't line up pixel-perfect in IE...
But does in the rest of the browsers.
I'm like "It works, and it's basically in the right place, and doesn't screw any other layout thing up. What's the problem?"
"Besides, IE is dead. Switch browsers."

This question seems to be more suited to codereview.stackexchange.com, since it seems that this question is primarily-opinion based, since it is based on preferences. — Algirdas Preidžius 38 secs ago
@Hosch250 And there are just so many browsers to test Chrome, FireFox, Edge, IE, Opera, etc.
And mobile adds another level of complexity.

5:42 PM
Another thing for improvement would be to use standard library more extensively. For instance, there is no need for you to define int Max(int, int), since there is std::max for you already defined in header <algorithm>: en.cppreference.com/w/cpp/algorithm/max . Then, naming could be better. 'arr', 'l', 'mid', 'r' do not sound very clear from code review point of view. And finally, as it was mentioned by @Fureeish , this should belong to CodeReview, not StackOverflow if there is no problem with your code. — Vaidotas Strazdas 19 secs ago
