Consumer & disposable helium tanks are no longer 100% helium and won't work with this method, just FYI
Can somebody help me understand this haskell code?primes = 2 : primes'
where isPrime (p:ps) n = p*p > n || n `rem` p /= 0 && isPrime ps n
primes' = 3 : filter (isPrime primes') [5, 7 ..]
I don't understand how one can use primes' inside primes' definition, since it is an infinite list.

(1/2) returns an int due to them both being ints. Do (1/2.0), or (1/2.f) if you were working with floats.

I'm guessing 1/2 is integer division, so the result is 0. Try 1.0f/2.0f, for example.

They're purposefully doped with carbon dioxide (CO2), oxygen (O2), or a denaturing agent like Benzene, to discourage use as an exit bag.
Try it today with any tank.
You will feel like shit right away and have the instinctive urge to breathe or get fresh air, just like using a closed O2 bag.
function multiplier(factor) {
return function(number) {
return number * factor;
};
}
var twice = multiplier(2);

>I'm trying to learn C, but I'm finding the K&R book to be increasingly difficult (and maybe old?),what books do you recommend for me (that's my first programming language, and I don't want to learn something else instead)?
C programming a modern approach is better.
But if you are learning programiming for the first time, you should learn the concepts first, and then the language.
I don't know if starting with C is a good idea though.
>>54729009
K&R is written for programmers who already know how to program, not kids who don't know what a for loop is.
Go read something else then come back.
>>54729042
It's not even freely available, and it's meant as a reference for those who are already experienced, and just want to... idk, make a C compiler or something
>>54729048
No can do.
>>54729067
I'm not an absolute beginner, I know what a for loop is.
(define (iter x) (begin (display x) (display " ") (cond (< x 10) (iter (+ x 1)))))
what am i doing wrong? it just prints 1 and 10 when i do (iter 1) but i want it to print every number between 1 and 10
>>54729051
that criticism isn't very constructive
>>54729088
Then you should have no problem with K&R.
Where are you having trouble, anon?
>>54729100
>what am i doing wrong?
using a dead language
>>54729110
nothing good can be constructed from what you did
>>54729117
I found myself unable to do the exercices in the book. I did the ones on the first few chapters, but then I couldn't.

Since Javascript permits that syntax for accessing individual characters in Javascript strings, why wouldn't be okay? It has nothing to do with C strings.
It's a bit weird not to just to str.length, though.

>>54729143
Post the exercise.
>>54729100
this works
(define (iter x)
(if (<= x 10)
(cons x (iter (+ x 1)))
'()))
>>54729179
it's to make a program in scheme that counts from 1 to 10. this is what i have so far >>54729100
>>54729182
i want it to print it though. i want output to be 1 2 3 4 5 6 7 8 9 10 if you do (iter 1)
>>54729190
I thought you were doing K&R?
So /dpt/, what's your current project?
>>54729179Exercise 1-20. Write a program detab that replaces tabs in the input with the proper number
of blanks to space to the next tab stop. Assume a fixed set of tab stops, say every n columns.
Should n be a variable or a symbolic parameter?
Exercise 1-21. Write a program entab that replaces strings of blanks by the minimum
number of tabs and blanks to achieve the same spacing. Use the same tab stops as for detab .
When either a tab or a single blank would suffice to reach a tab stop, which should be given
preference?
Exercise 1-22. Write a program to ``fold'
'long input lines into two or more shorter lines after
the last non-blank character that occurs before the n-th column of input. Make sure your
program does something intelligent with very long lines, and if there are no blanks or tabs
before the specified column.
Exercise 1-23. Write a program to remove all comments from a C program. Don'
t forget to
handle quoted strings and character constants properly. C comments don'
t nest.
Exercise 1-24. Write a program to check a C program for rudimentary syntax errors like
unmatched parentheses, brackets and braces. Don'
t forget about quotes, both single and
double, escape sequences, and comments. (This program is hard if you do it in full
generality.)
>>54729211
it does on my REPL
otherwise I think you could do a (display (iter 1))
>>54729100
You're using a begin, for one thing. It's not necessary when you're creating a new procedure.
Also, the problem is the cond. A cond form looks like(cond ((predicate0?) ...)
...)
You need all those parentheses, which you were missing. Consider using when if there's only one condition you're testing for.
>>54729245
really?
this is just playing with C stringsif (str[i] == '\t') fprintf(stdout, " ");
>>54729262
thanks. i keep fucking up cond and i keep trying to memorize the right form and think i get it
>>54729247
idk i'm just doing fib now, i know its creating the recursion its just not printing all the info

This is what you want I think
(define (iter x)
(if(<= x 10)
(begin
(display x)
(display " ")
(iter (+ x 1)))
(newline)))
But now you have to generalize it.
Write a function (count-iter start end) that counts from start to end.
(count 2 7) should print
2 3 4 5 6 7
>>54729268
fprintf hasn't been discussed up to this point.for (i = 0; i < TABSTOP; i++) {
printf(" ");
}

You are doing the SICP exercises by any chance? Don't worry about the display function right now, if you cons a list it automatically appears on the REPL.
Is R a meme or is it actually useful for data profiling/mining/stats?
>>54729367
i'm not doing an exercise right now. right now i'm just trying to do some simple programs in scheme to get the hang of it
(define (fibIter sum current target) (if (< current sum) (fibIter (+ sum current) (+ current 1) target) (sum)))
(define (fib x) (fibIter 1 1 x))
what am i doing wrong? it tells me
application: not a procedure;
expected a procedure that can be applied to arguments
given: 1
arguments...: [none]
>>54729458
That last (sum) is actually the number 1. And 1 is a literal, not a procedure.
>>54729458
You are invoking sum, sum it's not a proceure, drop the parentheses
>>54729505
what do i do instead then? i want it to return it
>>54729505
>>54729517
removing the parenthesis fixed it (still got a problem where its return 1 always but im sure thats just me being stupid) but i'm not sure why
i don't get what's happening
>>54729684
how is fibiter iteration if it's called within itself?
>>54729715
how isn't it?
>>54729684
I think you need memoization for iterative fibonacci. Iterative fibonacci is less straightforward than the recursive one. Have you tried writing the recursive before?
>code logistics
>>54729715
what
>>54729722
because it's recursion?
