You need to initialize variables in C, otherwise they will have random garbage. Set sum to zero first.
You also should handle user input better, because if someone enters a non-numeric character, your program will crap out.

Pleb here, working with stacks with ArrayLists for the first time on java
/g/, in what occasion would an insertion to a stack could it cause an exception?
I'm working on a project and the teacher is asking me to do a push method and make it throw an exception
I have an idea in C++ that I'd use try{} and catch(bad_alloc e) which I guess it's what can go wrong
tl;dr What type of exception should I catch in Java when pushing an item into an ArrayList?

You could catch it as just an Object, but better check the docs, it will tell you.
>>53618336
if your array is full and at max capacity
>>53618336
Java isn't real programming either.
>>53618336
if it is a circuller buffer, then you can throw buffer_full_exception or something. if it stack extends as you push then not_enough_memory allthough this one will be harder to produce

Haskell's got a lot of bad parts. Its type system is a mishmash of extensions upon extensions upon extensions. No totality checking, and lots of standard library functions are partial. On the topic of the standard library, it's in a pretty bad state, especially with respect to functors and all of their compatriots.
I still like it though, it's worlds ahead of every other practical language (so not counting academic or immature projects like Idris) out there in all respects but efficiency.

lel, did it overflow to the other side or what.
Hello, this morning I came across a code similar to this one and I've been trying to understand how it works. I was told that it just cast to an integer, but it's not enough for me. Mind anyone telling me what this is called? I want to search for further information but looking for "changing the integer value of characters inside an array" gives me no useful results.char buf[] = "Hello";
unsigned char test[UCHAR_MAX] = {
['e'] = 1,
};
printf("%d\n%d\n", test[(unsigned char)buf[1]], test[(unsigned char)'z']);
>>53618631
This is why C isn't considered real programming but rather rain dancing around a compiler. Why do you need to know this if you just want to write a program that does something simple like changing a character to an int?
>>53618417
I've taken to programming using the stroustrup style for C and C++. Basically, opening brace only goes on a new line for functions, and otherwise shares the line with the if/for/struct/whatever keyword. For if and else, the else keyword is not placed on the same line as a closing brace. This allows for easier commenting of these blocks if necessary.// comments look much nicer
if (condition) {
do_thing();
}
// if they are consistent like this
else {
do_other_thing();
}
For tabbing, I use hard tabs for indentation and spaces for alignment, using a "smart tabbing" technique that allows the code to maintain alignment regardless of tab width. My default tab width in my editor is usually 4.
I sometimes tend to put function types on a separate line from the name and argument(s). For example:static inline bool
does_thing(int thing)
{
// ...
}
>>53618631
god designated initializers are awful, thankfully they are not in C++
it justs sets 'e'th element to 1, I am assuming that code prints 1 0

I have not tested it, might not compile because of the static initialization or the ligature on "find".
I just realized you tried to get a computationally less expansive method, but, you're initializing your array on every single call, where it should only be initialized once.
The lookup table is pretty much needlessly big, for the problem it's trying to solve. You could reduce it by converting each character to a specific subset of the ascii (lowercase, for example) and applying an offset.

Working on a navigation mesh pathfinding system. Is there any rule of thumb for how many nav mesh nodes I want to make the program place in spots other than polygon corners in order to create more natural-looking paths and avoid wall hugging? I looked at Valve's famous L4D image and their placement of nodes outside of object corners/edges just seems completely random to me. Why would you subdivide all of that open space like that?
>>53622303
you make it be like it is and it do

Without a range, substring prints all characters after what you specify by extracting the rest. In your case substring(2) would remove the 0,1,2 characters from the string.
>>53622374
thank you
>>53622343
this isn't for an AI program this is how to make a predefined path
>>53622105
i assume that your talking about strategy game lvl AI path finding. so what you need to do is draw a straight line to the object and find the shortest path by (lazy method) finding all the possible combinations of paths with every combination of nodes and any path that crosses another object adds another node to skirt around it. select the shortest path.if your codeing this it shouldn't be to hard as long as there arnt too many objects with this path finding, not too many objects to skirt around, and its running on a decent computer. this is taken right out of the first 2 age of empires AIs.
What gets printed?Why?
>this isn't for an AI program this is how to make a predefined path
sorry misspoke
not how to make an AI path finding program

How do i access the other class without object or making static methods?public class Add {
public void multiple(int[] arr, int numb) {
for(int x = 0; x<arr.length;x++){
arr[x] = arr[x]+numb;
}
}
}
>>53623162
I think you can just do 'multiple()' without the 'Add.'
that or it's 'super.multiple'
I haven't used java for ages
OOP is dumb
>>53623184
HAHAha
>>53623162
>How do i access the other class without object or making static methods?
You don't. You can't.
Stuff in a class can only be accessed through instances (either directly for public members, or through instance methods for other members) or statically (either by using static methods or directly for public statics members only).

usually D-style functional programming / composition / generics
that sort of thing

It's great to get things done quickly and well, but I'd never get anywhere in the industry doing this because they all fell for the OO meme
>>53623424
There's clear and compelling reasons to use OO.
>>53623444
name three
>>53623474
>reasons to use OO.
generic plasticity
eliminates redundancy
inherent abstraction of sensitive data
>>53618270
>requiring all if statements to have braces
I do this too
>>53623493
>generic plasticity
a template system as capable as D's or (even) C++'s make these enormous unwieldy inheritance hierarchies that OO guys like to throw around completely pointless
>eliminates redundancy
the whole paradigm is redundant
what's the first thing you have to write in any java program?public static void main
a request that the language ignore the entirety of object oriented programming for a moment because every concept it introduces is superfluous
a concession that this whole 'everything is an object' meme is totally wrong
outside of those little toy examples with little pretty shapes inheriting each other, inheritance is almost useless
OO people can't write anything without trying to make up bullshit abstract noun classes so that they can pretend the 100 lines of procedural code they wanted to write is better implemented with 5000 lines of java where every function has parts of its definition hidden in 20 different files so they can 'reuse' it once
>inherent abstraction of sensitive data
What? You mean it does contract programming but worse?
Object orientation is fine in moderation, but when you have a language that demands you take an axe to your code, turn it inside out and stretch its skin over some sickly, meaningless object hierarchy, you get something truly horrifying

don't pretend every java project doesn't start looking like that after a while

learn java
https://docs.oracle.com/javase/tutorial/
but seriously, if you want to learn C#, then buying some textbook is probably your best option. which book, i don't know.
>>53619158
>>53619432
Murach's C# is a good book to start with.
Honestly, the easiest way to learn C# is to do a few simple GUI applications after you understand the basics of using Visual Studio.
At that point, you're just Googling how to do each thing you want to do. Then you end up Googling less and less and just writing.
>>53624129
>>53624185
>>53624216
if you do anything beyond fizzbuzz (hahaha, i know you neckbeards don't) it could feasibly happen for example that you change from integer to float arithmetic in your processing and then you get degraded accuracy with no indication whatsoever that something's is wrong
>>53624721
*and forget to change the type in one place
>>53619432
I don't really remember how I learned C#, but I'm pretty sure knowing C/C++ helped me A TON. IIRC I just started to mess around WinForms and .NET in general, it is really pretty straightforward and if there's something you don't understand (most likely because you don't know what the code is doing) there's plenty of documentation / tutorials / stackoverflow questions and really a lot more.
Hey, Im new to programming, about to hand in an assignment, and I have ran into a bug.
my assignment wants me to animate a simple 2d tank that places it self back into place when mouse pressed and changes color when key pressed. however after the half way point it wont change color if the tank has not been reset. im coding in Processing, also general tips for cleaning up my code and being more efficient would be appreciated.

Your code formatting is shit.
You have way too many variables.
Your variable names are shit.
Your have ridiculous amounts of duplication; use a loop or some shit
Honestly, I'm not even sure what language you're writing in.
>>53624840
You have magic numbers everywhere.
You're dealing in absolutes when you should be dealing in relativity.
If I'm at (2,2) and I want to move to places to the right I will be at (4,2).
I do not set my location to (4,2).
I add 2 to my x-axis location.color m1 = color(196,162,75);
color m2 = color(17,144,16);
color m3 = color(206,89,46);
Use MEANINGFUL variable names.
Name these 'blue', 'green', or 'red'.
Even ColorRed would be fine.text("ITEC 102 - Assignment 1",600,20); // This is the text.
Use MEANINGFUL comments.
Everyone knows it's text, dipshit. Stop insulting people.
Try to comment the WHY not the WHAT.fill(0,0,255);// The blue colour for the text
You defined color variables above, and now you're setting this one manually. Make up your mind.
At least you told us with the hell 0,0,255 was this time.
I can keep going if this is helpful at all.

babby's first Markov chains.
Number selector that you see allows for different magnitudes of connections, higher being more englishy, but tends to just imitate the posts if there isn't enough material.
Low ends up in gibberish, but it somewhat humorous; pic related.
You can generate based on a keyword, which just generates results and tosses those that don't contain the keyword. Application crashes if keyword is too complex or not found at the moment.

Code compiles but when I run it it doesn't do anything, as if it's running forever, but it shouldn't take time to compute.
It's Project Euler problem 7, by the way.
Can functions be used in conditionals in C like in Python? (I mean since they return 0 or 1).

>>53626101
Ignore this, I'm retarded.
>>53626054
Inp<pow(n, 0.5+1), shouldn't it bep < pow(n, 0.5)]? This is probably causing your code to slow down significantly.
Also, it should probably bewhile (p*p < n). This is nicer and faster.
