is it a mistake to mass produce a bunch of poorly polished, poorly programmed but functioning clones of simple games just to practice and to have a large volume of completed projects to show to future potential employers? because i honestly don't know what to program other than some kind of dream game project that i will discard within a week, and i really have only one or two finished projects to show for my mediocre programming skills

C++ still is not "clicking with me" as much as Rust did :^(

Probably because of no UFCS and the insane amount of verbosity when it comes to using iterators in data structures.

It sounds like he went too far. You are only supposed to be a girl(male). If he went on HRT then all of his masculine advantages are fleeting and thus will lose interest/ability to program.

Because you aren't freeing them you dunce. Doing free(tree) when tree is a pointer to a struct with pointers doesn't free the pointers inside it.

what is this

It's kinda funny after all these years, all the books and tutorials I read on c++ tried to instill this fear of pointers and templates on me. Now that I've programmed for so long, I realize how silly it all was, and that the only thing that made it seem scary was the worse case scenarios or basically being a dumbass, and then all the silly syntax with the archaic font being used at the time. It's just typical variables and generic types to allow you to not have to define different procedures for different data types. I know it should sound obvious, but just a "Oh, right" moment for me.

You could do

return year % 4 == 0 || (year % 100 == 0 && year % 400 == 0) ;

. Also, I suspect your code to be wrong when it comes to calculating leap years, although I'm not entirely sure.

>>62061678
If something is a multiple of 100 it's also going to be a multiple of 400, m8.

They think that they have to use OOP and C++ is only language those people might know well.
Usually if the engine is written in C it has comment like this somewhere
>There are plenty of C++ engines which do what I've done here and better. Pure C game engines on the other hand are much rarer. Corange provided me an outlet to practice my C skills. Of course if you are just linking to it you can still program your game/executable using C++.
Or other reason to use C
>Orx is mostly written in C (with some plugins in C++/Obj-C) but allows you to develop with it with any language that can interface to C (like C++ or Objective-C for example).
There's also that thing that C doesn't provide data structures in the standard library but I think this is not the reason because most C++ engines seems to implement their own data structures.

Is there any reason to use a Makefile over just running a bash (or whatever sh) script that compiles your shit?

well no shit, that's what i was asking: the reason for it: is it just because the "lack" of features or because it's easier to use already-made data structures that benefit from oop/other things

Is this intuitive?

>>62062484
Sorry. My bad. I'd say it's just a very general trend and the fact that games require a lot of developers. C++ projects with less experienced developers do scale better than C projects with less experienced developers.
I also think that because the games industry was dominated by C before (as an engine language, large variety in scripting languages) contributes too. The promise that you can write C code in C++ makes it a much smaller leap.

If the games industry was Cobol/ada/basic/whatever dominated in the past they'd probably have made a completely new language instead of getting on the C++ bandwagon. It's also worth noting that a lot of industries have very senior staff, the games industry has a comparatively young staff.

Object oriented programming was also widely used in games before when the game designs were very limited in scope. Most actual engine work is not object oriented anymore. It's just a common paradigm for newbies so you find that stuff in the surface level APIs for stuff like Unreal or Unity.
I also personally believe OOP scales well with inexperienced developers. The style seems to encourage very large fragmentation of code.

>>62062538
also, since you're talking about game engines, both the game and the engine is being written in C11

    Level level = scanLevel(LEVEL_PATH);
    initGameData(scanConfig(CONFIG_PATH), level);
    freeLevel(level);

    float lastTick = dgGetTime();
    while (!dgMustExit() && !g.lvl.over) {
        dgLoopInit(g.lvl.bgClr);

I'm going through the Tour of Go, slices exercise.

package main

import "golang.org/x/tour/pic"

func Pic(dx, dy int) [][]uint8 {
    result := make([][]uint8, dy)
    for i := range result {
        result[i] = make([]uint8, dx)
        for j := range result[i] {
            result[i][j] = (uint8(i) ^ uint8(j))
        }
    }
    return result
}

func main() {
    pic.Show(Pic)
}

Where are dx and dy arguments passed? I don't see where they are.
Also, I don't get the idea of explicit type conversion of INTEGERS. What's so great about that?

C++ is quite inconsistent about its own rules

#include <cstdio>
#include <string>
#include <functional>
using namespace std;

void print(string arg = "test") {
  printf("%s\n", arg.c_str());
}

int main(void) {
  function<void(string)> p = print;
  p("sdf");  // works
  p();       // won't
}

>>62063294
Never touched a single line of Go in my life but I think you're passing the function Pic to the function pic.Show() which then takes care of passing dx and dy to Pic.
Explicit type conversion means no surprises. Some people like it, some don't.

That's a stupid question that no one can answer. It entirely depends on the pace that you can absorb knowledge at, some people are retarded and don't know how to learn and/or cannot wrap their heads around some concepts that are trivial so it naturally takes them longer to learn than for someone that actually learns properly.

Quick rundown on WebRTC? My mate told me to implement a PeerJS API in java, but it seems to me that I would need a java WebRTC library in order to do that. Is there such a library that we could use in our proprietary app, or do I have to make one myself? If so, would it be feasible?

>>62064464
I understand.
But then theoretically would anyone take me on internship if I manage to "learn" languages on my own without any higher education?

>>62064555
For something so small you can just use retrofit. You don't need a service for such a short lived task.

>>62064610
Probably a slim chance when it comes to C, you'd be much more likely to get an internship while being new in some higher level language but still if you've got nothing going for yourself (like a degree/formal experience) then your best bet is implementing some interesting stuff and putting it up on GitHub, it won't guarantee that you land an internship but it'll definitely boost your chances a lot.

The new syntax may look like a step backwards in readability for the usual function declarations, but it does make it possible to use decltype to specify template function
return types:

template < typename T1, typename T2 >
auto Foo(T1 t1, T2 t2) -> decltype(T1*T2)
{
  ...
}

The problem that’s addressed here is that T1 and T2 are not in scope before the compiler
reads the eff parameter list, so any use of decltype has to come after the parameter list.
The new syntax makes that possible. Almost all modern languages have this feature.

Please do not pass std::string objects by value. You are unnecessarily copying data.

I forget my Fortran so I can't tell off the top of my head what version you're using, but unless you specifically have to hobble yourself to old version you should be using Fortran 2008. Caps lock isn't necessary since Fortran 90 I think
Also unless you need the entire history for a purpose, you shouldn't need to use an array to keep track of the previous value, single variable is enough.
Oh and testing doubles for equality is a bad idea, always use tolerances (ie, abs(target - current) < tolerance)

If you use R studio you can do all your stuff in GUI without ever having to bother writing line of R code.

i want to download youtube videos into mp3 by typing

>>62067304
I've been having the same problem anon

>>62068241

apparently you have to save the file as youtube-dl.sh file so that it can appropriately understand $1 or something

just add '.sh' and it should work, although now you have to do

./youtube-dl link

instead of just

youtube-dl link 

>>62068783

woops, it should be

 ./youtube-dl.sh link
