FizzBuzz is the word to be printed if i is devisible by 3 and 5. Otherwise it will be splitted by using the 4:8 slice.

I'we run into this really wierd problem.dxy = NthFibonacci(i)
x = startPoint.getX() + dxy
y = startPoint.getY() + dxy
I am trying to make squares that have lengts equal to fibonacci numbers. do dxy is the ith fibonacci number.
The problem is this:line 22, in <module>
y = startPoint.getY() + dxy
TypeError: unsupported operand type(s) for +: 'method' and 'int'
This is realy strange seeing how i do the same thing right above withx = startPoint.getX() + dxy
Any suggestions?

in graphics.py there is something called a Point. Here the definitions:
Point(x,y) Constructs a point having the given coordinates.
getX() Returns the x coordinate of a point.
getY() Returns the y coordinate of a point.
Link to documentation: http://mcsp.wartburg.edu/zelle/python/graphics/graphics.pdf
(the documentations is super smal).
Another weird this is that adding a print statement like this:dxy = NthFibonacci(i)
print(startPoint.getX(), startPoint.getY(), startPoint.getY() + dxy)
x = startPoint.getX() + dxy
y = startPoint.getY() + dxy
Gives me this:print(startPoint.getX(), startPoint.getY(), startPoint.getY() + dxy)
TypeError: unsupported operand type(s) for +: 'method' and 'int'

Because C++ makes a lot of very stupid design decisions.

postfix increment gets optimized to prefix increment by every compiler if the current value of the variable is not used. but yeah, relying on compiler optimizations is bad

Why is Lua so popular? It seem like a really niche language now that I looked at it.
>>52331755
I'm no Meme++fag, but I think endl flushes the buffer, while '\n' doesn't.
I think flushing the buffer is the behaviour you actually want here.
>>52331760
<< and >> is more readable imo
I'll ask this here as well because /wdg/ is so slow

You should write &&, but you absofuckinglutely can write 'and', you scrub. If you wanna be a smartass, try and at least be right.
>>52331730
>code doesn't work
>unnecessary lines
>>52331801
because gmod
>>52331755
It's short for newline then a flush.
C++ waits until you have enough shit in the buffer to output then does it all at once or does it before an input because I/O is expensive. Doing it every line is stupid unless you need to flush the buffer for some reason or you need the output at that exact moment in when running.
>>52331801

Lua is popular because it's very simple and has a tiny ANSI C interpreter. If you embed Lua into your application, you only need to ship a few hundred kilobytes for the interpreter, instead of much more (possibly in order of hundreds of megabytes) for some other shit. Also, since Lua is ANSI C, it'll run on pretty much fucking any platform and can be compiled with almost any C compiler.

>>52331928
Also if you have something likestd::cout << x << y << 4 << z;
I wanted to shift y by 4 to left but I don't think it gets shifted.
Solution of course would be (y << 4) but I would argue that it's less readable than the normal way of writing functions.
I don't program in c++ so I don't know if it has << as shift operator but C should work in c++ so I assume << is also shifting operator.
>>52331615
no you're supposed to do it like this

It's very easy to learn. It can be embedded in anything and usually is (vim, lualatex, video games, etc.). It's fast (it's register-based, not stack-based like CPython) and the JIT is really fast. If you already know how to program it might take you 2-3 days to learn it completely.
Unfortunately, it seems to be losing a lot of steam recently. Look at the mailing list. Mike Pall left the JIT. And projectkepler is in perpetual maintenance mode. No one really wanted to leave 5.1 and it's killing the language (plus built-in integers in 5.3 being a pain in the ass).

They can shift buffers but they can also shift bits in number which makes it really non-simple.

Yeah, didn't want to type out the entire question to just get called newfag or whatever is trending on 4chan these days.
Anyway, fuck it. I'm writing a program in java to read in data from a text file. The text file has 2 columns and unknown number of rows. The first column contains integer values and the second column contains what's called CPT codes. I just read those in as strings. Thing is, the integers in the first column can be any number. For example, the text file I am using to write the program has 11185 rows and the values in column 1 range from 1 to 8000. The CPT codes need to be printed together depending on the first column value (CPTs with value 1 are printed together, CPTs with value 2 printed together, CPTs with value 167 printed together, etc). What do I need to use to try and keep these CPT codes together based on the value in the first column? A simple array doesn't work obviously. Do i need to use some sort of HashMap? Or a multidimensional array? Again, I'm new to programming, so the answer might be obvious to some.

correct. Out of the 11185 codes on the test .txt file I am using to write the program, 7699 of those codes have a value of 1, around 2000 have a value of 2 (I am looking at one CPT code which has a value of 405, the next value is 450 which has five or so CPTs associated with it). So, yes there are multiple codes associated with each value usually, but not necessarily always, it's completely random. Also, I need to check, but I don't think the CPT codes are unique (i.e. there may be a CPT code listed 2 or three times but with a different value each time)

Well didn't think about that.
But still it could be just macro to call toString method on class or print it's memory address and for numbers print the value.
cout takes argument of any type.
so
cout << a << 4 << endl;
could as well be implement as cout(a, 4, endl);

print output or i #"or" returns the first value that is True, empty strings are interpreted as being False. On the occurrences where startslice and endslice are the same output is an empty string.

because "FizzBuzz"[4:8] , that's the part that slices "FizzBuzz" into two parts either "Fizz" if it's just [0:4] or "Buzz" if it's [4:8], it doesn't make any sense whatsoever for the second number to be larger than the actually len("FizzBuzz") which is 8

Either awful at explaining, or you have no clue how the operations affect the slicing

8+i would give a number larger than 8 you imbecile, you don't need a number larger than 8, the part after 8 can either 1 nothing or 4, going from 0 to 7, so you end up with [0:8-1] = [0:7] >> means print the whole fucking word

I'm trying to bind directly to a data object but for some reason shit ain't having it.<TextBox x:Name="txtNotifSec" Text="{Binding NotifSeconds}"/>
http://pastebin.com/AU3UBfdu
I set the value to "3" at runtime, I output it to console to check 100% that the value is correctly set.
But for some reason the textbox only ever shows "0" and everything I've tried results in either "0" or nothing at all.
>>52333731
why are idiots always the most obnoxious.
it's quite clear you understand neither the code, the order of operation nor the simple question of why there two consecutive minus signs
for(int i=1; i<101; i++){
if (i%3==0 and i%5==0) cout << "fizzbuzz\n";
else if(i%3==0) cout << "fizz\n";
else if (i%5==0) cout << "buzz\n";
else cout << i << "\n";

I'd give her the capitalist D
>>52333731
You're a fucking idiot
The algorithm never ends up at [0:7] (which isn't the whole word, it's FizzBuz)
The slicing either gives you [0:4],[4:8] or [4:4], the latter of which is an empty string, which evaluates to False and prints the number instead
Don't explain shit you don't know
>>52333728
anyone??

Forgot to add the slicing can also give you [0:8]

I was explaining to him how slicing works not how it works in this example. It starts at 0 you fucking moron, it ends on 7. That's a full word "FizzBuzz". I can take the screenshot of my console right now if you want!

Guys, I got it below the syntactic level.
For some reason, (i**2)%3 is always 1 when i isn't a multiple of 3, never 2, which could perfectly happen at first glance, but that's some arcane number theory or what.
For some reason, the same is true of (i**4)%5.
Then, I found out empirically that 8--i**4%5 is equivalent to 8-(-i**4)%5. Given that i**4%5 is either zero or one, (-i**4)%5 will be 0 or 4, which is an useful coincidence, since we need that exact value for the second pivot.
This is too much, Geffrey, it can't be a coincidence! Think about it, the illuminati ramped up the whole formulation of FizzBuzz 50 years ago, so that one of them could "discover" this "trick" now and destroy the old world order! They are already here, and Guido is one of them! Fucking Reptilians

I was just fucking with you, that's good. Most people are too scared to go with anything other than Arduino.

What part are you talking about? The conspiracy theory one or the number theory one? In the former case, you deserve to die since you're redpilled and you do nothing.

If you're talking about negative modulos, we all knew that

It's required by some languages. C# and Java come to mind. That's something I like about C++ is you can ignore OOP for small shit.

>planning for the future
Worst idea ever.
If your plans change, you will have wasted your time writing code you can't reuse.
Better break everything up into tiny functions that do only one thing, then you'll have lots of reusable code for later.

>>52333828
A* is an algorithm that finds the shortest path between two points when there are obstacles in the way.
How does OpenGL treat scope when doing stuff like compiling shaders and binding objects?
I'm guessing it doesn't give a fuck, so you can just copy the handle outside the function and keep using it?
>>52334174
not very good for DRY tbqh
let's say you write a function to calculate the sum of n numbers. if you wrap it in a class it's easy to extend to integers, floats and doubles whereas a single function would need to be copy pasted
>>52334231
>What are you talking about?
It's in plain english. The only other time you want variables floating about is because it's used only and contained within a certain file, and at that point, it's pretty much a class. If you have this variable floating about that you call from elsewhere, you can't really describe its context, why it's in that specific place and it'll be more difficult debugging trying to keep track of where these mystery variables are located
>>52334285
>a single function would need to be copy pasted
>what is parametric polymorphism
>>52334290type Point = (Int, Int)
add (x1, y1) (x2, y2) = (x1 + x2, y1 + y2)
The context is the function itself. Why would you make a class for Point when you can just do something as simple as this?
>>52334321
you mean generics?
they're cool I guess, but it's a bit of a mess without a consistent interface in which case it's pretty much the same thing as polymorphism

Er, what?
> I'm guessing it doesn't give a fuck, so you can just copy the handle outside the function and keep using it?
Object "names" (i.e. handles, unsigned integers returned from glGen* or glCreate*) are either unique within a single context or within a group of contexts which share data.
Other than that, they're not "scoped". All state that's not part of a container object (e.g. VAO or FBO) is part of the context. So if you only have one context, it's effectively global.
>>52334360
I think you misunderstood my post, or thought I was the guy talking about functions when the initial complaint was classes with 1 variable.
In your instance, there is no variable floating about, you've defined a type and a function for it
>>52334321
>parametric polymorphism
"parametricity" means you can't do anything with it, like void*
Too bad people misuse 9-syllable phrases to sound smart.
>>52334360
Because not all languages support functional constructs. What does the symbol 'add' refer to? Is it add point1 point2 or add int1 int2? Compare with Point.add v.s. Int.add, or even better: int1.add(int2) and point1.add(point2). The latter is also a lot less verbose and also allows you to define safely int1.add(point1) and point1.add(int1) if you want.
