Things you did well
Readability - everything was well organized and spaced neatly.
Initializing variables within your for loops/adhering to the C99 standard (which is the minimum you should abide by in my opinion).
Marking your function arguments as void when you don't take in any parameters.

I have written the following code as the level rendering part of a game engine I am writing. I am very happy how it works but as it is the background / level graphics made up of individual blocks it needs to be quick.
What it does it look take the graphics from a resource loaded elsewhere and sc...
I'm within my first few weeks of programming and this is my 1st language. Should I be using different code than what I already chose to write?
Problem:
Write a program that reads 10 numbers and displays distinct
numbers.(i.e. if a number appears multiple times, it is displayed only

Can I get some pointers/critique/comments on the following model? (p.s. performance seems great... tested all methods up to 10,000 records)
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class o7th_Model extends CI_Model {
private $msg;
private $last_id;

Another simple example:
if (wpa_s->mlme.ssid_len == 0)
return -EINVAL;
Why the unary minus? Is this (usually) done for functions that return >0 on success and <(=)0 on failure, or is there some other reason?
It seems that users are still using the code-challenge tag for challenge-oriented questions that do not correspond to the site's occasional voted-upon challenges. We already have the programming-challenge tag for off-site challenge programs, but it's understandable that the two tags sound simila...
I'm Pops, a Community Manager at Stack Exchange. Though it saddens me to say it, not just one but two of your existing moderators are stepping down for personal reasons. Over the past week and a half, I've been working on finding replacements, and I'm happy to announce that two avid Code Reviewer...
I applied for a job and they asked me to write code with the following requirements:
Get a "toolbar offer" description from
http..update.utorrent.com/installoffer.php?offer=conduit. Parse the
bencoded (see http://en.wikipedia.org/wiki/Bencode) response and
extract the URL of the binary...
While reviewing a code the reviewer replied to the coder that, "Strictly do not use ternary operators in super calls "
Is there any rule of thumb like ternary operators should not be used in super calls ?
Solved the ford-fulkerson algorithm, which is too vast to explain it comprehensively here. Check Wikipedia for Ford-Fulkerson and Princeton lecture on Ford-Fulkerson.
Looking for code review, optimizations and best practices. Also I request you avoid mentioning renaming GraphFordFuklerson and u...

Task:
Given a dictionary of words, and a set of characters, judge if all the
characters can form the words from the dictionary, without any
characters left. For example, given the dictionary {hello, world, is,
my, first, program}, if the characters set is "iiifrssst", you should

My advice: split up that main function.
How can I test this C program for "efficiency"? The most interesting usage is that it returns negative output for large enough input, otherwise the behavior is about expected e.g. the usage is when compiled:
$ ./a.out 19011
19011 => 19013
Will you suggest how to improve it for portability (uni...
This is self explaining example with usage in doctests:
class Switch(object):
"""

... if case(1, fall_through=True):
... print 1
... if case(2):
... print 2
... if case.default:
... print 'default'

I am just starting out in my clojure journey and I wonder if anybody can point out my beginners mistakes in my function below that simply reverses a list. I know that there is already a reverse function so this is purely for learning.
(defn rev
([l]
(if (= (count l) 1) l (rev '() l)))
([...
I am going on with refactoring my code base while migrating from Python 2 to Python 3. I am using generators to make reusable components this time as I am more comfortable with them this time then last time. But there are times when I am stuck at their use. Like below example. These two are essen...
I have class that implements Set and List. Programs works fine in Java6 and Java7
public class SetList<V> implements Set<V>, List<V>
{

}
With Java 8 , this does not compile. Error is

Is this the right way? Any comments on the hash functions? If asked a question like this in an interview, do I need to follow all OOP concepts(because I am using Java)? Like encapsulating the variables by writing getter and setter functions?
