/dpt/ - Daily Programming Thread

This. It's just reversing the bytes instead of the proper code points.

Why do you keep hurting my feelings?

I'm neither a bot nor an autist. I transcend space and time.

The world must be better if Lisp is more popular.

this is not a valid thread until JS doll-chan is posted

non-ascii is good for
1. foreigners
2. emojis
3. nothing
I only wish that I could more easily oppress characters that aren't in early Latin, like J

check your privilege, bigot

#include

then use the fucking standard int types
int_fast32_t for example

#include

docs.rs/nix/0.15.0/nix/unistd/fn.getuid.html

and what would you use? Another language where the I/O primitives return optional types?
to print out the chars in reverse? how?

>and what would you use?
char, because im not a ctard caveman
> Another language where the I/O primitives return optional types?
Rust is better at handling strings so yes

...
in favor of Elm?
don't say we're just giving up, doll user!

You're fucking retarded. int is used instead of char for a reason.

Imagine using a language that doesn't have default values for prims.
imagine actually dealing with uninitialized errors in the current year.

>char, because im not a ctard caveman
cplusplus.com/reference/cstdio/getchar/
The function returns an int though..

>char
getchar() returns two things
1. a char
2. EOF
what's your plan to distinguish between #1 and #2?

My shitlang that is lower level than both C and sepples can do that in two lines. There must be a better sepples implementation than what you posted.
_main =: _sl strreverse strgetline

>getchar
EWWW Learn C++ first, cavemen

if you've optimized your shitlang for the expression of trivial programs like this, at least don't brag about it.
that's like implementing HQ9+ as other than a joke.

I have no interest in learning the worst language that has ever existed.

imagine having to deal with a shitlang like rust

Does it shit the bed when you try Unicode?

Who's this girl?

yea, ur precious c is implemented in c++ nowadays.

who cares about commie jew encodings

I can't learn C++ because my textbook hasn't been published yet. What do you want me to do, learn from a pre-2000 book?
But since you've learned C++ user, tell me how I'm supposed to read input char-by-char except with getchar() ?
bear in mind that char c; cin >> c; skips empty spaces because someone thought scanf() had the right idea.

I went to school for CS and dropped out over 6 years ago.
I learned basic JavaScript and C.
I want to complete my degree and maybe have a career in development/security.
I can't really right anything right now except for some hello world shit.
What are some good resources to brush up on/learn coding so I pass a reentrance exam or apply for a job?
I couldn't into maths so I ended up dropping out and basically haven't tried to do anything computerwise since.

so im trying to make my own dummy profiler, my idea is to have a singleton that contains a map , then i just plan the begin_timer(name) and end_timer(name) anywhere i want
how does that sound?

lol what

en.cppreference.com/w/cpp/string/basic_string/getline

Not if you know it's unicode beforehand. I just have to index the strings in chunks of 2 bytes instead of 1.

You couldn't be more wrong.

conceptualize the odor

>how should I do it?
>you shouldn't do it
oh. thanks.
yeah, although it's really attractive, the idea of making my code longer and uglier and worse, with no gain whatsoever, not even an efficiency gain given stdio buffering, just so I can avoid 'int c', I think I'll stick with int c.

sir i have done the needful please send payment thank you

#include

int string_length(char*);
void reverse(char*);

main()
{
char s[100];

printf("Enter a string\n");
gets(s);

reverse(s);

printf("Reverse of the string is \"%s\".\n", s);

return 0;
}

void reverse(char *s)
{
int length, c;
char *begin, *end, temp;

length = string_length(s);
begin = s;
end = s;

for (c = 0; c < length - 1; c++)
end++;

for (c = 0; c < length/2; c++)
{
temp = *end;
*end = *begin;
*begin = temp;

begin++;
end--;
}
}

int string_length(char *pointer)
{
int c = 0;

while( *(pointer + c) != '\0' )
c++;

return c;
}

Fucking hell, none of you should be allowed to write code.

Yes, that was made apparent in K&R C.

Also my new problem is from K&R C; I need to write a program to remove all the \t characters from a text stream.

smells like hot summer and warm puffy thigh

Most of /dpt/ doesn't write code. That's why there are so many weird opinions here, like hating right tool for the job thinking.

The only right tool for the job is Lisp.

Best first language?
Also fucking atom looks so pretty but visual studio seems so much better.

post some code, nerds

Just finishing up a python selenium script that goes on the local lawyers directory and gets the name of all the lawyers practicing in the area.

Python. You can learn it quickly and it makes you instantly employable. After that, venture out into whatever langs you feel like.

Common Lisp

I just read all of PEP8 and it doesn't dictate project naming conventions anywhere. Why do most Python projects force "Py" in to the name?

To be fair, this is the only thing I've posted that I've actually written:

#include
/* read a string into s[] one character at a time, count its length, then print out s[], one character at a time, in reverse */
int main()
{
char s[100];
int c, j;
int i = 0;
while ((c = getchar()) != EOF) {
s[i] = c;
++i;
}

for (j = i - 1; j >= 0; --j)
printf("%c", s[j]);

printf("\n");
}

And I'm only (semi) proud of it because I've just started teaching myself C.

>Best first language?
whatever's most aligned with the asker's interests. Learning to program is hard to the point that language differences don't really matter (just look at Guido; he did research and came to a bunch of conclusions and then threw up his hands and said fuck it, made a language contrary to research, and then let people shit features continuously into it).
these days, JavaScript is probably the best for anyone genuinely new to programming. They definitely have a JS interpreter around, and they can immediately play with it and get results.

most langs do stuff like that.

they don't force it. They want it. They're flashing gang signs. It's basic human behavior.

Probably Python. Its syntax is simple so you can dive in pretty easily. You could also try C if you want more in depth knowledge of how computers run so you can write more efficient code.

depends on your interests, user. python is a good starter.

C is for doing the wrong thing very fast

if you just want to kode, not really, just use JS libraries to do all the shit for you
you can create GUI applications without knowing how to do division
but knowing how to do division is a good indication you have a brain smart enough to copy paste code from stackoverflow (no kidding, people actually do this, so dont feel bad if you ever kopy kode)

Overflows lol

Doesn't defining the string length prevent overflows though? Or would I need to do it manually?

I like how your version only accepts a single line of input. That's a good, uh, improvement.

What are you talking about? I don't care about muh benchmarks, what bothers me is the lack of unicode support and how I had to generate non standard warning

>I don't care about being slow as shit
>what bothers me is the lack of emoji support
the C++ elite isn't what what I was led to believe.

All languages with C in their name were a mistake. How a single letter can curse programming forever in so many ways is beyond me.

My highest level of math is highschool calculus. Is it even worth trying to git gud at programming unless I go back to college to take some more advanced classes?

Attached: 1510773152497.png (882x758, 16K)

nope
it's not worth going back to school either

Nope, you have to do a check on the length yourself. C is notorious for these types of bugs

What about Clojure?

i'm dumber than you and people pay me to do it

Math has no impact on programming, as long as you have the knowledge of the language and any kind of deductive reasoning you can get a job as a code monkey.

not even tears sufficient to flood the Earth will make me care about emojis, sweetie :^)

Then how the fuck do I learn this shit? I'm sick of being a brainlet. I did fine in calculus but I was a lazy fuck during college (double major in two meme humanity degrees) and I am regretting it bigtime. I just graduated last may and I feel like ending it all.
