Is there a quicker way to find the second occurance of a character in a string without compromising readability? This seems slow.string numberString = NameAddressComboBox.SelectedItem.ToString(); /* can't just get text when we add dynamically, it gets previously selected item */
int dashcounter = 0;
for (int i = 0; i < numberString.Length; i++)
{
if (numberString[i] == '-') /* remove from the beginning of the string, to the second dash, to get the number on it's own */
{
if (++dashcounter == 2)
{
numberString = numberString.Substring(i+1, numberString.Length-(i+1)).Trim();
break;
}
}
}
Basically I have a string which isstring - string - number
and I want to get rid of thestring - string -so I can get the number on it's own and parse it
>>53537658
>obvious bait
>>53537673
it's not bait senpai, pls no bully. also this is slightly better but I don't like the substring bitint dashcounter = 0;
for (int i = 0; i < numberString.Length; i++)
{
if (numberString[i] == '-' && ++dashcounter == 2) /
{
numberString = numberString.Substring(i + 1, numberString.Length - (i + 1)).Trim();
break;
}
}
I wish 4chan would stop fucking up my formatting and making me fix it manually
Let a0, a1, a2, ... be an integer sequence defined by:
a0 = 1;
for n ≥ 1, an is the sum of the digits of all preceding terms.
The sequence starts with 1, 1, 2, 4, 8, 16, 23, 28, 38, 49, ...
You are given a106 = 31054319.

Typo?
Anyways a1015 is 16921.
I currently have a PostgreSQL function that returns data of a user with the specified ID.
Non-admin users should be able to view only their own data.
How do I implement this with PostgreSQL 9.0? I read that row-level security is only available in 9.5, but the database will run on an old piece of shit uni server with no chance of upgrades.
I'm still amazed how Mozilla managed to make a language uglier than both C++ and Haskell combined.

Hell yeah Umaru edition
>>53538149
I already have that. It stores the logged in user's and runs queries based on that ID. I was just wondering if that was enough security.
Do you think a function that takes an ID and returs a table row of data corresponding to that ID is overdoing it? Would a view query with "WHERE id=specified_id" be sufficient without any security compromises?
Visual C++ 32-bit and 64-bit compilers recognize the types in the table later in this article.

>"YES! Small incremental changes in a dying language are so exciting!!! XD"
>>53538235
Unsigned - can only be positive, uses all bits in the memory to represent the value.
Signed - can be either positive or negative, uses the last bit to represent whehter it's negative or positive and the rest for the value.
>>53538235
unsigned means the number can't be negative.
1110 = 14 if unsigned
1110 = -2 if signed

If you've 100% verified that they're correctly logged in before, then I see no reason why you'd need more security.

The language and whether it's complying with its standard is irrelevant here, it was merely used to represent that when an integer is 4 bits wide, 1110 will represent -2.

I wrote my first terrain LOD system today.
It's ugly as fuck, creates horrible cracks everywhere.
But hot damn it is fast. At least when compared to rendering the whole terrain at maximum detail level. And it looks really neat in wireframe.
I guess I need to figure out some proper continuous LOD system now. I can't leave those cracks there.
>>53539106

that depends on binary representation of numbers. C does not enforce such a thing.

well i think it is NP-Complete but i'm not sure.
anyway my question is:
- you have the items and their values and weight. (that's the classic problem).
what if i have the same item but with different weight and value to choose from ?
for example:
- item 1 has cost 2 and weight 2
- item 1 has cost 3 and weight 5
- item 1 has cost 6 and weight 7
- item 2 has cost 1 and weight 1

Yes. It doesn't compile without return.

I'm sorry your mother dropped you on the floor after you were born (could also explain why you're a tripfag).
>>53540334
Emacs.
>>53540316
No. Besides doesn't your function currently return an empty list rather than "nothing".
>>53540296
C++ is literally the best high-performance language

Wrong! Return is required.
>>53540334
Pycharm, maybe the educational edition
(I don't use it, but I love IntelliJ for Java)
>>53540379
So? The language i still poorly designed.

Same. Unlike Egglips, IntelliJ just works.

Seconding that. Why learn one """IDE""" per lang? One editor to rule them all. Plus an """IDE""" is basically a walled garden : you don't want to live without freedom, do you?

I'm not talking about python, autismo, I'm talking about the general concept of returning from functions and how it's mandatory in some languages!
>>53540473
>JavaScript
>blazing fast
bwahahahahahahaha
>>53540481
Not him. In other languages, functions have to return a value that fits its signature's return value. Python method's start with def, no return type in the signature, so whatever you return is up to you
>>53540461
>What you working on now chap?
Project for the FAA.
>anything new to not-lisp?
Not lately, no. I think I'm gonna go back in and work on my other meme language, SP4.
>>53540316
Look at the syntax. How else does the compiler/interpreter know your function has ended?
You could say "Well it'll just look for next function" but then how does it tell between a nested function (if even allowed) and a new function, after implicitly closing the current one?
>>53540506
The V8 engine makes it really fast. It's fast enough for programs cucked by IO.
When are Java apologists going to let go?

What is a good way to store a board like this and score it? Squares are easy, but odd hexagon shapes are hard, and it's only further complicated by the fact that people can play on both the triangle and line shaped spots.

Thanks Anons, I added the return()'s. Seems to work. Here's my code so far. I don't understand much about programming but yet it's fun to play with Python.http://pastebin.com/aesVXPXa
Noob programmer here just starting and i have a problem with this:
#include <iostream>
#include <conio.h>
#include <string.h>
using namespace std;
int main()
{
int i,j=0,k=0,str_1=0,str_2=0,str_3=0,space=0;
char sta[40];
char stb[40];
char stc[100]={ };
cout<<"Enter sentence: "<<endl<<endl;
cin.getline(sta,39);
cout<<"Enter Second Sentence: "<<endl<<endl;
cin.getline(stb,39);
for(i=0;i<40;i++)
{
if(sta[i]=='\0')
{
break;
}
else
{
str_1++;
}
}
cout<<"The first sentence has: "<<str_1<<" characters"<<endl<<endl;
for(i=0;i<40;i++)
{
if(stb[i]=='\0')
{
break;
}
else
{
str_2++;
}
}
cout<<"The second sentence has: "<<str_2<<" characters"<<endl<<endl;
space=str_1+str_2;
for(i=0;sta[i]!='\0';i++)
{
stc[space]=sta[i];
space++;
str_3++;
}
for(j=0;stb[j]!='\0';j++)
{
stc[space]=stb[j];
space++;
str_3++;
}
stc[space]='\0';
cout<<"The third sentence is: "<<stc<<endl<<endl;
cout<<"And has "<<str_3<<" characters "<<endl;
return 0;
}
why it won't print the stc string?
thanks in advance, again i am a noob.

Trying to implement a Plan9 like system throughout my house, got a media center hooked to my flat screen. A HTTP + file server (for holding all my backups and for sandboxing my web development) and now a media server (I can stream netflix better than the last 3 blue ray players I bought) and I'm about to add another media streaming PC in my room (using plan9 userland with arch and sshfs to mount all of the /home/ directories under one master /home/ on the HTTP server.
tis noice friendos.

You know, Anon, you could have linked to the proposed standard instead of the comments section of Reddit.
Also, that faggot talking about "named loops"... we have that in C. It's called labels and gotos.

Use a const reference instead of copying the string by value. Doing it the way you're doing right now invokes the copy constructor.

>You know, Anon, you could have linked to the proposed standard instead of the comments section of Reddit.
I would have to click every single link.
Anyhow, named loops are shit, one of the documents is a report and the half-float thing is useless. However, I see no indication that they have a higher possibility of getting into the standard than this for example: http://www.open-std.org/jtc1/sc22/wg14/www/docs/historic/n424.txt
>>53541176
Yes we will. We're pretty close even. My implementation is just unoptimized shit.
Well, technically ray tracing won't be real time anytime soon, but path tracing (which is better) will.
My program is a whitted-style ray tracer so reflective materials keep bouncing lightrays off and refractive materials spawn 2 new rays each time they're hit.
With path tracing you employ stochastic techniques and only trace 1 path per ray (simulating a photon, sort of). Then you increase the number of samples per pixel to get a less noisy image. If you accumulate that, eventually it will converge to a photorealistic image.
