How bad were you when you started programming ?
I love this maymay
>>51846874
i know rite
>>51846864
Pretty shit, I am still pretty shit but I get what I want done somehow. Pretty sure I would make most people here insane, but I am not a programmer. I am a civil engineer, I just make tiny scripts.
Still shit I'm afraid OP.

Nowadays I know C, C++, C#, Java and Python, Big O notation, Programming Patterns and more. /g/ may shit on those languages, but if they land me a decent paying job, I'm down.
>>51846890
Never this bad, but I remember my hay days. I haven't grown because too lazy to actually use my programming skills.
I had really trouble with for and while

>>51847015
How long has it been since you were in school anon?
>tfw not even a FizzBanger yet
I wrote a "hello world" application and my program told me to "fuck off"
>>51846864
To be fair, this one isn't that bad.
It's lazy as fuck, sure, but it doesn't show any fundamental misunderstanding of basic programming concepts like >>51846890 does.
I can't even fizz buzz yet.
>>51846864
i remember putting together shit in AutoIT. i was so bad.
at some point i had to generate a unique file name. i knew how to generate one and i knew how to check if it existed, but i didn't understand the concept of loops. so i made a block that generated a name and checked if it existed, then copy-pasted that like 3 times. if all 3 checks failed, it exited with some error message, saying it couldn't find a unique name.
i also had this 1337 hax0r script that logged in to public mail servers and sent mails with faked sender addresses. i didn't know how to execute commands in a console directly, so my script just opened a cmd and send keystrokes to it. tons of static sleep() too.
>>51846864
I thought making my variables one letter long would help reduce how much memory my program used.
Also, my first language was Java and I had no idea what OOP was, or what a constructor was, and as far as I knew anything under the hood was pure magic to me.
>>51847086
I'm 28 and have gone back to school this year after working for 2 years for a laboratory (not as programmer), before that I went to the shitty game-dev school, which couldn't land me a job. I'm now learning to be a proper all round programmer.
I don't want to even talk about it anonymously especially since I'm still shit years later. Always room for improvement, never good enough.
When I started with Python on Windows, I thought the only way to run programs was to use the IDLE that comes with the installation.
>>51847379
Wooo.
At my school, we are taught c++.
People think that the only way to execute their programs is through Visual Studio.
>>51846864
I remember when learning C back in school, instead of using strcmp() I did something like this in a project once:
>if(string1[0] == string2[0] && string1[1] == string2[1] && ... )
Fun times.
>>51847015
>studio.h
>>51847462
I... what
>>51847532
Well, it worked, so ...
>>51847015
exactly the same to me, and what’s more, as English isn’t my native language, it sometimes takes me time to understand the name of functions and libraries (cout => the output for C, stdio => standard input/output)
Also, learning how to make algorithms in general was quite hard to me.
>>51846864
I still remember the rationale they gave for this when I sent a pull request was "this was more readable than a for loop".
Like what the fuck are you on? Who doesn't understand what a fucking for loop does?
I'm still shit.
>>51847754
I wrote something for an embedded device one time and the person with me wanted me to unroll the loops because he said the people who may need to maintain it later might not understand it. Why would you work on these things as C programmers if you don't know C? I don't even.
When I was 10 I was autistic af so I taught myself C++
By the time coding was actually taught to me in education I could program effectively

I had the chance of having my father teaching me BASIC on his old ZX81 tho, quite a useless language, but it taught me the bases of programming in general. But alas, I was too lazy to go as far as I wish I had.
>>51847523
That's how I read it ! How was I supposed to know it meant Standard I/O?
Should I feel bad for doing badly on Topcoder problems?
>>51847205
It's not even lazy, a for loop would be quicker to write.
>>51846864
I didn't know the difference between "if" "if else" "else if" and "else"
>>51846890
What if they input a question mark or whatever
>>51847205
It displays a lack of awareness regarding hashes. And timestamps. Or any other better naming scheme.
Heck, seems like it would've been cleaner to generate a random number, convert it to a string, and use that as a name. Without knowledge of the problem domain I can't really comment further...
I wouldn't put it past myself to do some of the things in the CS graduate images. It was only for the first few attempts though, since I knew I was being retarded and searched for a better way. Started mostly with C.
>>51848541

>>51848568
When I made a file hosting site, I had it generate 8-character ID's consisting of upper/lowercase letters and numbers. In the extremely unlikely event of a collision, it would keep trying until a unique ID was found. I don't know why Pomf's developers had a limited amount of tries, that seems retarded. I still chalk it up to laziness more than anything else.

>>51848800
Why would you have 8-character ids in a non-memory constrained system anyway? And why not use a hash of the filename and a salt (like timestamp and a PRNG output concatenated) as an id?

>>51849283
Fine
>>51849103
A couple of reasons:
1. Short IDs allow for compact and uniform URLs. This is also why Pomf used 6-character IDs, I'm assuming.
2. The chance of a collision in such a naming system is around 1 in 2E14 - in other words, non-existent, so it wasn't a real concern.
I could have used hashing, but it's not as straightforward to implement and essentially results in the same thing anyway.

Not true. It's easier, and the code looks less like shit.
But yeah, I'm totally nit-picking here.
really bad
however, even though i was self taught for years, i don't think i really developed bad habits
I got meme'd by /g/ in 2010 and started programming with C (before that I've done some bash scripting, editing PHP configs / spaghetti code thru documentation / simple html fuckery) and I've done things like
>write functions then find out an equivalent was in the stdio / stdlib
>cascade include local project files resulting in tens of lines of includes to other files in every file (and somehow making it work)
>make linked lists that add new links infinitely until 4 GB of memory fills up and Xorg gets killed for lack of memory

Really? We also learned C++ in my school, but we only used Visual Studio for the intro course. After that, we were working in the command line and gcc/g++. No offense but the people at your school must be kinda stupid. command line compilation isn't even that hard

>>51851547
I thought it was related to 'iterate'.
>>51851588
I'm finally googling it and I'm getting everything from it being involved in summation to "index"
funny enough, I'm not getting iterate or item.
>>51851684
I think it was index actually, probably got iterate from somewhere else.
>>51851547
>>51847015
>>51851588
It probably came from a number of things, but if I had to guess, it's common to see it as a subscript for summations. Just my two cents.
>>51851547
I always saw arrays as matrices. Since i and j are used so much in elementary linear algebra, I got used to it without questioning it.

People are saying that the common subscript you're talking about may have also come from index.

To me is was basically the same as asking "why do we use X as a variable" I probably would have questioned it in linear algebra if I had gotten to that first, but I started programming before I took the class, so I ended up wondering about it there.
When it comes right down to it, someone probably picked a letter and everyone stuck with it.

I think it's important for people to remember that it's more important to have non-elegant looking code that does its job rather than elegant looking code that does a shitty job.
>>51851912
That's actually the reverse.
The most important thing is that your code can be used, modified, and maintained by any other developer in the company.
If that means it has to be slower or less efficient, then that's what happens. You can always come back and refactor well-formatted code later, but it's much much harder with "ugly, performant" code. Especially because you run the risk of a massive ripple effect.
>>51851912
This was true when computers were slow as molasses. Nowadays it's better to have readable code especially with the advent of self optimizing compilers.

We were taught that i stands for index and as in the index of the of the array. As to why we also used j and k for 2-3 dimensional arrays I just assumed we were going alphabetically from there.
I learned HTML when I was a kid to work on vBulletin Boards with my friend.
That's it. I'm going back to school (at 25, bleh) to learn code. Hoping to get a 2 year degree in Computer Science and then transfer to a 4 year school to learn even more.

I wasn't too bad at programming itself when I started. It just sort of clicked with how I think.
The thing that makes me weep looking back on my beginning was my ego and how I'd convince startups to hire me even though I had only been at it for a few months. A lot of that code is still out there in the wild. I live in constant fear of the day when I'm called in to fix one of those things when it inevitably breaks down.
Imagine legacy code built by someone with only 3 months of university Java class. Built in JavaScript (because they're pretty much the same, right?) I still go to some of the sites that I've built every now and then, hoping they've been replaced, or at least fixed for God's sake, but they rarely are. I charged a lot too. I'll carry this guilt for the rest of my life.

Practice is all you need. Look through code or solutions from others, look what they did and how it differs from your code, and then think why they did it that way. Often it's easy to see why yours is better or (most of the time as a beginner) worse.
>>51856066
>it is and I just can't see it yet.
It's this one. And that's how it will be for a long time to come. The worst programmer on your team will always be you from a few months ago.
You're at the point where everything's super hand holdy and nice, but you're about to be able to see just how deep the rabbit hole actually goes. As long as that doesn't end up scaring you off, you'll be fine.

Don't start programming in an IDE like I did. You won't learn any of the things the IDE does for you and treat it like black magic. Start off with just a text editor, javac and java.

To be honest, I don't understand what's wrong with that.

The problem isn't what I did, the problem is how I did it.
In certain use cases, (x+y)/2 will cause an overflow, while other ways of writing an average function will not. Thus the code is shitty.
>>51856960

C functions are written in lowercase though. That could very well be Java or even C# I'd assume.
>In certain use cases, (x+y)/2 will cause an overflow, while other ways of writing an average function will not. Thus the code is shitty.
Do you really work with numbers that big? Or am I missing something?
I started out with VBScript. I once made a Lord of the Rings quiz entirely out of Message- and InputBoxes. I also had a VBS in my Startup folder that would query you for three passwords. It would literally just open up an InputBox, then another, then another. Yes, you could absolutely ignore it. Sadly I lost those scripts.
Next I learned BlitzBASIC which was aimed at kids learning how to make simple games. Those programs are also lost to time. They were pretty decent in terms of variable names and whitespace, but I didn't optimize at all and often didn't use loops, copypasting large sections of code. Still no documentation and almost no comments. Horrible.
>>51856998
>C functions are written in lowercase
C functions are written however the programmer wants to write them. There's no one way it must be done.
>Do you really work with numbers that big? Or am I missing something?
The whole point is that there are certain use cases (really about 49.97% of all possible use cases) in which the code will break when there is better, but still simple, code that will not break.
It's also an old /dpt/ meme.

strlen returns the length of a string not counting the null byte, he's subtracting one from that
there's no need to check if every number up to a given number is divisible by that number to determine primeness
also checking if it's not equal to itself is a condition that will never be true
>>51857197
You only have to count up to and including the square root of a number to check if it's prime. For every divisor below a number's square root there must be a corresponding divisor above the square root.

Not very. And I was 8 when I started. I think the same is true for the great, great majority of us. Typically, your pic is what happens when you let first-bumpers program.

For everything else, there's experience.

You should always use For loops when possible, and seek to transform While loops into their For equivalents.

>You should always use For loops when possible, and seek to transform While loops into their For equivalents.
Whenever possible, your code should do exactly what it's supposed to do and nothing else. To foster this, every component of a program's control flow should be as obvious and clearly defined as possible. Further, every assumption and mechanism you use should be programmed, and should be programmed in the most constraining way possible. You the programmer should make unintended behavior as difficult as possible.
This is why if you have a function doSomething that takes a string, returns an integer, and doens't change the object's state, you should useint doSomething(const std::string& thing) const {/* code */}
instead ofint doSomething(std::string thing) {/* code */}
For loops have a defined beginning, a defined increment, and a defined endpoint. You can see these definitions in the first line of the loop. A while loop only has a defined endpoint. You have to look elsewhere for the increment and beginning, and that means it's more likely that mistakes will creep in without your knowledge.
As the size of a project increases, the importance of constraining scope becomes greater. For large, multi-team projects with revision history going back over a year, constraining scope is the single most important part of the job. Further, regardless of project size, a smaller scope is ALWAYS better than a larger one: the less things the programmers have to think about at any one moment, the less likely they are to make mistakes.

But if all you want is an infinite loop (maybe with a break somewhere) why would you use a for instead of a while?

The first time I encountered for(;;) I had to question why the fuck that even compiled, but it's pretty obvious why while(true) is just an infinite loop.
