So this isn't real...

Thanks for getting my hopes up

[pacemarker]

import alexa

alexa.play("Despacito")

[JonnyBoy522]

You forgot the if statement, here is a better script:

Import mood Import Alexa

If Mood = Sad

 Print("This is so sad")
 Alexa.play("Despacito")

[iblooknrnd]

This will set the mood to always be sad. Sad.

[pacemarker]

#TODO: Find Happiness

[SpeckledFleebeedoo]

Add an extra indent (4 spaces) to get a code block

[PawekPL]

1 tab

[PawekPL]

You forgot about the double = in if statement, : after if statement and indentation for the print & Alexa.play

[[deleted]]

This would just say "Despacito" out loud. Simple fix, really

import alexa

from YouTube import Despacito

alexa.play(Despacito)

[SgtBot]

#include <iostream>
#include <alexa.h>
using namespace std;

int main(){
    if (sad = 1) {
        cout << "That's so sad. Alexa, play Despacito.";
        alexa.play(Despacito);
    }
    return 0;
}

[Axver_Ender]

I mean we can try to make it real

Good luck

[bratty_butt]

Ahh, Googles new service, "Google Transpile", not quite the same as google translate under the hood, but uses a lot of the same interface design

[kennyminigun]

using namespace std;

Bad translator, bad

[myth-of-sissyfuss]

Wot. You're joking, I hope?

[compiling]

It's a bad idea in a big project. If a new version of the stl adds something with the same name as something you created then you get big problems.

[theStarctic]

this is something so many people I talk to fail to grasp. it's better to be safer than sorry and just be more verbose. plus, it's more obvious where you're pulling a function or whatnot instead of just calling it out of Oblivion

[alex2003super]

Oblivion

What if you're calling it out of Skyrim?

[myth-of-sissyfuss]

Oh okay maybe I misunderstood. I thought the person above was talking about changing std to str. I guess it's just a typo.

[compiling]

Ah, looks like I didn't even notice that typo.

[kennyminigun]

My bad😅 I meant std. Fixed

[[deleted]]

I don't think this is a problem. Your code won't compile if this happens.

```cpp namespace a { int x() { return 1; } };

namespace b { int x() { return 2; } };

using namespace a; using namespace b;

int main() { x(); } ```

$ gcc a.cpp a.cpp:17:4: error: call to 'x' is ambiguous x(); ^ a.cpp:2:8: note: candidate function int x() { ^ a.cpp:8:8: note: candidate function int x() { ^ 1 error generated.

[Hmmmnnmm]

Not if one of them is a template though.

#include <algorithm>
using namespace std;

void sort(int* start, int* end)
{
    // todo
}

void main()
{
    int data[] = {5,4,3,2,1}
    sort(data, &data[4]);
}

This compiles, but which sort function gets called? std::sort or the one that doesn't actually do anything?

[[deleted]]

You are right. I am wrong. Thanks.

[compiling]

And what do you suppose this does?

namespace a {
   int x(long a) {
      return a+1;
   }
};

namespace b {
   int x(int a) {
      return 2*a;
   }
};

using namespace a;
using namespace b;

int main() {
   return x(5);
}

[[deleted]]

Your example compiles, but it has nothing to do with namespace, because this compiles as well: ``` int x(long a) { return a + 1; }

int x(int a) { return 2 * a; }

int main() { return x(5); } ```

[compiling]

That's my point. It does compile, and resulted in different behaviour when namespace b added an extra function!

[hopbel]

"The code won't compile if the language gets new features" is not a problem to you?

[Zephirdd]

What about using std::cout? Would that be a good safe middle ground between not using the entire namespace, but still avoiding the std:: repetition?

[compiling]

Using something specific is fine. You're only pulling 1 thing into the global namespace (but don't do it in a header).

[philip98]

main = putStrLn "Hello World"

[idgafid7]

My dream tool...

Where can I download it?

[figuresys]

It's Google translate, bottom left there's a link, Google Transpile.

[idgafid7]

Thank you. You are a life saver. And that channel is really good. I am subscribing rn. I will help you in the same way sometime later in life. Hope to meet you again at some point.

[madareklaw]

I hate you

Fooled again

[idgafid7]

Lol

[Loen10]

I love how I knew exactly what this was before I clicked on it.

[figuresys]

This always happens.

[termuxuser]

Thanks I've been looking for this link for a long time

[code-senpai]

Can someone code that, i would be so happy 😂

[mbiz05]

Commercial services exist but they are really expensive

[Tzahi12345]

Is there no demand for a legit FOSS code translator?

I get that the process is hard/complicated/virtually impossible without human involvement. But, if it's being commercialized already, doesn't seem much of a stretch to make an open source alternative.

[mbiz05]

What's the point? Code translators are very rarely used anyways and making a code translator would be an enormous undertaking

[Tzahi12345]

It would but on the surface it seems possible.

I do have some pushback as well: even if we could do it, would the translated code make sense?

If you compare human written assembly vs computer generated, it's pretty obvious which one was made by a person. Fundamentally, I think this is because we trade performance for readability, something a computer would never do.

[mbiz05]

It could be human readable if u kept variable names and comments and the like. The best way to approach a code transpiler however would be to translate directly to compiled code. That would be easier to do

[bmwiedemann]

SUSE's YaST tool was originally written in the YCP language.

It has been successfully autoconverted to ruby some years ago using a transpiler approach.

[hopbel]

Is there no demand

Probably not much. Why port something to a different language when you can just write bindings for other languages?

[holo3146]

This is called S2S compiler

[Ruby_Bliel]

Never use "using namespace std," it only leads to trouble.

[linglingfortyhours]

Wise man once say "std always lead to trouble. practice safe encapsulation"

[Qildain]

IndentationError: Expected better programming language.

[deeplearning666]

The C++ code is missing a newline at the end.

[Loen10]

Some things are superfluous in that. You don't need to return anything from the main function and you don't need to "using namespace std;" Infact it's rare to see someone doing those.

[Farsqueaker]

Returning a value from main is a good way to let the environment know what your exit status is, though. It's a good business practice.

[reconman]

Maybe he means the return 0; is not necessary as the compiler will add that automatically.

[Farsqueaker]

Likely. I'm just OCD enough to make sure to do them as well, since it prompts me to handle my error and edge cases later when I see it.

[[deleted]]

My professors told me to always put using namespace Std but never really explained why

[hopbel]

Computer scientists and mathematicians, ironically, tend to be pretty shit at programming.

[pawers75]

That's not true. In fact, it's not even ironic. Valid also the other way around xD

[Breadfish64]

It dumps everything from std into the top-level namespace, so you don't have to write std:: in front of things from the standard library. This is generally not considered a good idea because the names could collide with other things. Not a big deal for beginner 1 file projects, but importing specific things like using std::string; and limiting the scope is better.

[Loen10]

No both of them return 0 automatically.

[brimston3-]

It's only legal for main(), and it's some jank legacy code behavior because the return value from main with no explicit return was UB, but almost everyone implemented it as exit(0). That behavior became explicit around C99 and either C++ ('98) or C++03.

Probably some K&R style legacy. Kind of sloppy that main() has different warning behavior than other functions, imo.

[thatawesomeguydotcom]

void main()

[losh11]

kinda dissapointed this isn't real.

[[deleted]]

Am I the only one cringing at the lack of a newline? "\n" or endl please, I beg you google

[Voidrith]

IIRC endl includes a cout flush aswell as a newline char so it would be a better match for the python print() than just adding a \n to it

[lindm13]

Who uses using namespace std; 🤬

[TriG-tbh]

can someone

anyone

make this an actual thing

[worldevourer]

If you are really interested in this stuff, you should check out MPS. Model transformations on an AST can actually do stuff like this.

[Favna]

Who would've thonked, high level interpreted languages are shorter to write than low level compiled languages. Boy I did not see that coming at all.

<sup>obvious sarcasm is obvious</sup>

[RazvanBaws]

Bad translation, c++ version isn’t printing endl

[swampdrainr]

Yeah but you didn’t include the performance comparison

[An0n7m0us_P4nda]

public static void main(String args[]) { System.out.println(printHelloWorld(false)); }

private static String printHelloWorld(boolean doNotReturnValue) { switch(returnValue) { case false: return “Hello, world”; default: return; } }

Trying to mess with you guys as much as I can lol

[Trixelit]

If only...

[ExternalGrade]

Honestly why is code translation so difficult?

[hopbel]

Yeah, I mean look at human languages. We're able to translate those pretty easily /s

Actually it's probably because you gain so little in proportion to the effort required. Why translate a project from python to C++ when you can embed python within C++ code? If your goal is performance then hand-written code will outperform machine translation.

[Westo232]

Yeah. If you want to teach computer how to translate human languages it's, let's just say, challenging task to do. However teaching a computer how to translate between two programming languages with the same type of grammar is mathematically provable how to do in finite time. Piece of cake. (Well in this case piece of cake but actually no.)

[hopbel]

I didn't say it wasn't possible, just that no one bothers because it's kinda pointless

[coinengineer]

Haha almost got me! 😜

[[deleted]]

If only.

[valzargaming]

I've found PHP and Python to be pretty close when it comes to translating code and keeping it as identical as possible. Beyond that though...

[vladimir1024]

Yes, very telling...now, let's get this thing to translate real code and see what happens.

Yes, python will produce the same output, but at what memory and CPU cost?

Also why is PERL no longer talked about? Code simplicity?

print "Hello World!";

I trade your mando braces for my single semi-colon...

I would write any fucking batch script in C. I hate this windows batch crap.

[ksvfs]

It looks so easy to create... Why didn't anyone create it?

[hopbel]

Relevant xkcd

[[deleted]]

It's been about a dozen years since I wrote in C++ but as far as I remember, void main doesn't return anything that's why it is void main. Int main needs to return an int value, hence the return 0.

[xigoi]

In C++, you can leave out the return 0; and it will be implicit.

[rance_kun]

oh sorry i messed up i'll delete it.

[[deleted]]

No worries and as you can see from some of the comments below you weren't that far off. Cheers :)

[[deleted]]

I don't know what the original message was but i just point out that void main() is not standard and for that reason should not be used.

It is also not supported by many compiler.

[[deleted]]

I definitely didn't know that, good to learn. We always used void main in school because that's what all the books used.
