It's French fries day.

Come on, that's not even proper food anyway.Let's not start a war over the wording.
:D
 
I think there was a memo years ago that we were to call them Freedom Fries now.
Okay, so I had this post on the main site (http://codereview.stackexchange.com/questions/87085/simple-comparison-of-sorting-algorithms-in-c)
and I got some great responses. @LokiAstari is the top answer and so I'll start with those. Anyone who knows C++ I'm grateful for your help.

Loki said it is better to use `std::cout` everywhere than to put a `using` command at the top. Why is that? Is the danger that I or some other person might name another function `cout`?

Why are some functions automatically placed in the global namespace and others aren't? When I put #include <math.h> in the p

Q: Using std Namespace

paoloricardoThere seem to be different views on using 'using' with respect to the std namespace. Some say use ' using namespace std', other say don't but rather prefix std functions that are to be used with ' std::' whilst others say use something like this: using std::string; using std::cout; using std::c...

 
11:23 AM
C functions are in the global namespace for compatibility reasons. Including <cmath> instead of <math.h> should put them in the correct namespace.
 
To answer your first question, yes, it's about namespace collisions... I, myself, find it a little silly and if I found a library with namespace collisions to the standard lib, I probably wouldn't use it.

Q: DRY Kleisli wrappers with lens

Danny NavarroThis currently does what I intend: nested :: Request -> Maybe Response nested = runKleisli . unwrapArrow $ WrapArrow (Kleisli (preview (prefixed "/name") >=> app1)) <|> WrapArrow (Kleisli (preview (prefixed "/surname") >=> app2)) where prefixed :: Text -> Prism' Request Reques...

 
@Morwenn, so if I used <cmath> instead, how would that change things? Would I still be able to call the functions without a cmath:: or something like that?
 
But that's not the gospel according to C++
If you did using cmath (or whatever the namespace actually is), the namespace qualifier can be omitted.
I don't understand the disallowance of using std myself.
 
This is confusing to me still, sorry (I did my graduate work in Mathematica, but now think I need to learn a real language to leave academia lol)

I just changed the preamble of my C++ code (is it called the preamble like it is in LaTeX?) from `#include <math.h>` to `#include <cmath>`, and it compiles just like before.

Why can I call `floor`or any other function on this page http://www.cplusplus.com/reference/cmath/ , without prepending the namespace? But I can't do that with `cout`?
 
11:30 AM
If you can't use using std, then why does the using keyword exist? What's it for?
 
from reading responses on stackoverflow, it seems the world would be better if there were no using
:-)
 
I can understand preaching against not using it for obscure libraries.

@JasonB Generally speaking, it's more "don't use using in header files".
The reason in that a header file can be included by anyone who might have defined a function/class with the same name.
You can generally use the functions imported from the C standard library without std::, but you can't for the ones that only exist in the C++ standard library and not in the C one.
It's fine to use using namespace std; in source files (not headers), provided you know that it won't cause name clashes.
@nhgrif using has many uses: using declarations, using directives, type aliases and template aliases.
And constructor inheritance too.
Or more generally importing functions from a base class.
 
I can avoid it, I want to go from what I do now, which is writing a program for the purpose of doing a calculations, to (hopefully) programming for a living. So I've been lazy in the past, and would rather just do what is easiest for every calculations. But I want to get to know good programming practice.

So what is the reason I can use `floor` or `exp` without prepending a `math::`?
 
I told you: floor, exp, etc... are actually from the C standard library. C++ must compile C, so it must support using these functions without prepending the namespace std::.
 
@Morwenn you say don't use it in headers, yet I always see people bitch about it in the .cpp file.
 
@nhgrif That's "double problem": actually, it's generally safe to use it in the .cpp file, but example files tend to be entirely .cpp files, so people got accustomed to using namespace std; everywhere, so other people started to ban it from everywhere.
Somebody who uses using namespace std; in an example .cpp file may not know that it's bad practice to use it in a header file, hence an overall warning in answers on CR.
But some people tend to get passionate about banning it from everywhere.
 
Then our C++ answerers should write better answers.
 
11:58 AM
It's hard to teach teachers.
A few months ago, I used to put warnings about using namespace std; everywhere too.
There is an equivalent problem with people teaching that names beginning with a single underscore are bad.
 
And I'm here just worrying abou thow my GUI should look
 
@skiwi Thinking about UI and actual users is also a real concern :)
 
Especially when the users will be CR people ;)

If I have a list of users that belong to a specific object, does it make sense to need to go into 'edit-mode' to add/remove users?
 
12:06 PM
With no context... Maybe?
 
Alternatively you'd have Add and Remove buttons in the 'normal mode', just by viewing the object
Maybe that would be better though
 
You are asking about UI without screenshots... So... I guess we can just ignore you and be rubber ducks.
 
That would be a possibility, yep ^
Might even be a smart one
 
@Morwenn why are names beginning with _ bad? I use them regularly (not in C++ though)
 
@nhgrif Names beginning with a double underscore are reserved to the implementation, as well as names beginning by an underscore followed by an uppercase letter, as well as names beginning with a single underscore in the global namespace.
Complicated rules, so people tend to turn them into "don't use names that begin with an underscore".
 
12:15 PM
... Welp, guess I'm glad I don't write C++...
Who needs so many weird complicated rules...
No wonder the C++ chat on SO is full of such terrible people.
 
C++ rules merely follow the C ones.
 
@nhgrif what language do you use that is free of weird rules?
 
And POSIX likes to reserve some additional names too, but people tend to violate POSIX restrictions.
@JasonB Brainfuck is free of weird rules.
 
I mean rules that the compiler doesn't enforce.
 
One of the major problem is that compilers can't enforce rules that major libraries have been violating for more than 30 years.
 
12:20 PM
@Morwenn, that is fantastic - thank you for bringing that to my attention
 
Right...
Objective-C, to my knowledge, has none of these rules like this, despite being built on top of C.
 
I wouldn't put my head on it.
 
Experienced Objective-C programmers certainly don't treat Objective-C novices in the same way C++ novices get treated in SO's C++ chat room anyway.
 
Well, the C++ chatroom on SO is subjectively one of the worst places to be on the SE network if you're not an old regular :)

@JasonB There are good times to use using (I am writing a blog article on that in the future). But like all tools they can be misused. And using is one of those tools that has been heavily misused. Its worst in books because they misuse it to save space.
But people learn from books and take this misuse as normal.
When using other peoples libraries use the prefix. When writing your own libraries you can use the using clause to simplify your own source files. So if you are writing a library MyComp::MyNameSpace then using becomes very useful to simplify the code.

But I smiled and said, "No sweat, I'll train you. The first command you
learn is HELP" and proceeded to type it in on the console terminal. So
the data center manager, the shift supervisor and the eight day operators

slowly and the directors were spellbound. I decided I had better check up

It is folklore after all..... Internet folklore at that.
 
In finance, Black Monday refers to Monday, October 19, 1987, when stock markets around the world crashed, shedding a huge value in a very short time. The crash began in Hong Kong and spread west to Europe, hitting the United States after other markets had already declined by a significant margin. The Dow Jones Industrial Average (DJIA) dropped by 508 points to 1738.74 (22.61%). In Australia and New Zealand the 1987 crash is also referred to as Black Tuesday because of the timezone difference. The terms Black Monday and Black Tuesday are also applied to October 28 and 29, 1929, which occurred after...
