Having fun teaching students how to write programs without explicit recursion in python. They froze when I showed them how z = lambda f: lambda x: f (z(f), x) works but later accepted my breaking of their veiw of python as a procedural language

>>61056804
can solve all of them as captchas use machine learnig to recognize which is correct. It proves it can beat itself

>he doesn't wrote a float wrapper which tracks the amount of bits of precision that remains after every operation at compile time and gives him the value range to give compile errors on before every operation
I question why this isn't a standard feature in languages. It's not hard to do. All you need is to define the input value range once and you've got the entire program covered.

>>61057142
>optional GC
I don't see why people care about features like this. There's millions of libraries for memory management you can use. The standard will probably be one of the worst systems as it usually is.

>>61057193
check the prior two threads

>>61057200
I've read the discussions and it's about std::sort vs qsort. Not a C++ implementation of qsort vs C implementation of qsort.

Not to mention the entire argument there was about how the C qsort couldn't inline the comparator function because they weren't compiling the C standard library with the program. So it's not even about the different functions it's about the environment.
So silly.

>>61057191
They already did, you can use strings in unions now.

I see that just as the nature of metaprogramming. And programming in general. You can always do wrong things. With metaprogramming you're effectively writing more code so it's easier to write lots of junk.
I don't like how languages prefer catering to the lowest common denominator. (see rust, go, python)

>>61057172
>It's not hard to do.
it's literally impossible

double f = 0
int iters = user_input

    f = floating_point_op_a f

    f = floating_point_op_a f

What do you think about JAI?
I hear the research community is interested because game programming is similar in that they share a lot of the ideas of writing fast systems and high level code in front of those systems yet they always demand as much performance as they can get (with research there's always a gain in execution time, with games you always want the best graphics or whatever).

I find the similarities interesting. Is it all just about simulations though? What do /sci/-programmers do other than simulation? I guess the LHC does a lot of data processing/analysis. But they use python as a front-end. I don't see the point.

Read the entire C++ spec and consider every part of it with every other part of it in the spec. It's an O(n^2) or greater process. Then start complaining at compiler writers because nobody follows the spec perfectly.

i am too sleepy to actually write the code right now but here are the steps:
1) use a macro so that it will be inlined
2) realize you can't because qsort is recursive
3) turn it iterative instead using the fact that all recursive algorithms can be rewritten as iterative depth first traversals of a state graph

1) no you don't, you can use in-node colors and parent pointers
2) you could also just use an amortized dynamic array as a stack
3) it doesn't have to be generic, it just has to hold pointers

https://code.woboq.org/userspace/glibc/stdlib/qsort.c.html
This implementation of qsort isn't recursive. It's ripe to be inlined, all that's missing is defining it as a macro instead of a function. No need to bother with the DFS of the state graph, it's already there.

Pretty much. But so early it basically matches the hellish description proposed in the post I quoted above.

Not this though.
>a language where everything is UB, and you control how specific that UB is.
This was necessary because int was B's only type. It was so very much B's only type that it wasn't even called int, because names are for distinguishing things of the same sort from one another, and when you only have one thing, you don't have to do that.

I've had a few successful iOS games in Unity, making about 10k a year from them. Now, if I want to create a game engine that will eventually run on both the 3DS and Switch, but don't want to use C/C++, what language(s) can I use and how would I start making sure it can run on the 3DS and Switch?

It will look something more like this.

# "get" is like SQL's "select"
get thread from this
# The only code you can run at top-level is code to retrieve or create threads.
# In this context, "this" refers to the program.
call it main
# You can only define variables before you declare them.
# The definitions are stored in a queue.
# You pop the queue with the "call it" keyword, which takes a name to declare and bind the definition to.
in main: # "in": send commands to a thread or the internal context of an object
   get 1
   call it x
   get function over a and b # "function over": lambda
   call it plus
   # There are no global functions. The only global variables are threads.
   # To create functions, you have to bind lambdas to local variables.
   in plus: # if "in" is called on a function, it provides the body
      put a + b # put is the opposite of get
   get x plus x # all lambdas must be called with infix
   call it y
   do print y # except unary lambdas since infix is impossible in that case
   # also, "do": like "get" but for lambdas that don't end in "put"
   do kill this # beyond top level, "this" refers to the current operand of "in"

Without the comments:

get thread from this
call it main
in main:
   get 1
   call it x
   get function over a and b
   call it plus
   in plus:
      put a + b
   get x plus x
   call it y
   do print y
   do kill this

>>61058330

Suggestion to increase badness: variables' types can only be inferred at declaration time so they can't be used in get expressions without specifying their type.
Example:

get number called x plus number called x
call it y
do print number called y

new to programming, retard here. I started taking a summer course at a local college on C. I've got a program that compiles fine (I'm using visual studio) and when I run the program from visual studio it runs fine.

but when I run the actual output .exe file, it doesn't print the last line, doesn't say press any key to continue, it just exits immediately after the last input. what do?


#include <stdio.h>

int main()
{
float miles, mpg;
float fees, tolls, cost;

printf("How many miles do you drive per day?\n");
scanf_s("%f", &miles);

while (miles < 0) {
printf("error: please enter a valid number for miles.\n");
scanf_s("%f", &miles);
}

printf("How much do you pay for a gallon of gas in dollars?\n");
scanf_s("%f", &cost);

while (cost < 0) {
printf("error: please enter a valid number for cost.\n");
scanf_s("%f", &mpg);
}

printf("How many miles per gallon do you typically get?\n");
scanf_s("%f", &mpg);

while (mpg <= 0) {
printf("error: please enter a valid number for mpg.\n");
scanf_s("%f", &mpg);
}

printf("How much do you pay in fees per day, in dollars?\n");
scanf_s("%f", &fees);

while (fees < 0) {
printf("error: please enter a valid number for fees.\n");
scanf_s("%f", &fees);
}

printf("How much do you pay in tolls per day, in dollars?\n");
scanf_s("%f", &tolls);

while (tolls < 0) {
printf("error: please enter a valid number for tolls.\n");
scanf_s("%f", &tolls);
}

float sum1 = fees + tolls;
float sum2 = ((miles * cost) / mpg);
float sumfinal = sum1 + sum2;

printf("Your cost per day is $%.2f dollars\n", sumfinal);

return(0);
}

>>61063953
just add a getchar() after your last printf to wait for a character input so it doesn't inmediatly exit

>>61058635
leaking memory isn't unsafe... in fact in this particular case since self is moved here its dropped regardless

>>61057218
Hence C++ is faster because it doesn't have those problems.
Templates solve it, and it optimizes for the specific type.

why many modern languages doesn't require specification of primitive types? is there any advantage?

>>61067425
what do you mean? like specifying the size of the type? in Rust you have u8, i16, f32, etc.

>>61067697
i don't know for sure, i was looking for some python, ruby and haskell i think and they would just do something like this:
a = 15
without declaring this a

>>61067425
>>61067697
Isn't he talking about implicit type declaration? Like you leave to the compiler to decide which type it is. If this is the case, i find it pretty shit.

>>61067847
mm yeah but at that point it's not really a primitive type, is it?

even so, if you can declare something like:

type i32 = 32 bits

it doesn't really do much for you because the compiler is still tying the syntax to the type. basically, primitive types are gonna have special syntax anyways, so it makes more sense to keep everything to do with them as part of the compiler. if you have syntax plugins it might make a little sense but personally it doesn't seem like a huge gain
