A brief background, I'm working on a game prototype for a simple strategy game. After I created a number of possible jobs I wanted to create something to manage them. This is the first time I've attempted something like this so code review would be helpful.
I created a set of methods that adds...
This question is a follow-up to a previous version of this program, which I wrote because I found it annoying that VLC Media Player (which I love) prevents the screensaver from starting after playback of media has ended on my Ubuntu 12.04 system.
There have been several changes which are listed ...
When a user presses a key in my game, their avatar can move down, left, right or up. By move, I mean their avatar animates while various other things move around them on the screen. This is accomplished by raising an event from the input handler. The Player class listens for this event, finds the...
This is homework, so I'll just get you started.
#include <stdio.h>
#include <string.h>
int main(void)
{
char *buff = "this is a test string";
char* substr;
strncpy(substr, buff+10, 4);
puts(substr); // prints "test"
}
So for your pyramid problem, you will want to take the subs...
This is my code for a server using EAP (Sockets).
Is AsyncOperation.Post is the right way to raise thread safe events?
AsyncOperation.Post states:
Invokes a delegate on the thread or context appropriate for the application model.
PS: Is there any other mistake in the code i.e something t...
I'm trying to write a javascript library to allow inheritance with knockout.
The fundemental problem when implementing inheritance in knockout is that each knockout observable is it's own instance, thus if you try this:
x = function () {};
x.prototype.m = ko.observable();
y = function () {};...
Given an expression string exp, write a program to examine whether the pairs and the orders of “{“,”}”,”(“,”)”,”[","]” are correct in exp. For example, the program should print true for exp = “[()]{}{()()}” and false for exp = “[(])”
Complexity:
Time complexity: O(n) where n is length of th...
As suggested in the 2nd monitor, I'd like to put some code to do an in-place reversal of a linked-list up for review:
#include <iostream>
struct node {
int data;
node *next;
};
node *reverse(node *list) {
node *prev = NULL;
node *next;
while (list) {
next = list->...
This answer will focus on general style of your code.
Use constructor chaining. One of your constructors can call the other one, like this:
public StackExchange(int num) {
this(new BigInteger(String.valueOf(num)));
}
This helps removing a bit of code duplication.
Declare by interface, no...
In Optimizing unique partitions of integers, I just want to write the quadratic equation nicely. Having to resort to ASCII art to do so is just ridiculously frustrating!

You don't use delete after allocating nodes with new, resulting in a memory leak. As a general rule, delete should be used in the same way new was used.
In this case, have an identical for loop and use delete on each node:
for (int i=0; i<10; i++) {
delete n;
}
With these two loops, you...
I've created a linked list class in Python, but I'm not sure how to enforce only passing Node objects into the insert routine.
# linked list in Python
class Node:
"""linked list node"""
def __init__(self, data):
self.next = None
self.data = data
def insert(self, n):

Problem Statement
Generate as many distinct primes P such that reverse (P) is also prime
and is not equal to P.
Output:
Print per line one integer( ≤ 1015 ). Don't print more than
106 integers in all.
Scoring:
Let N = correct outputs. M= incorrect outputs. Your score

I have just joined my new company.
In the current code-base of my new company, the coding-standards are a bit different from those I have used before.
For eg.
string b = "SomeMockTest"; //Current company's coding standard.
is used instead of
var b = "SomeMockTest"; //I used this before i...

I wrote an webapp recently which allowed me to export my gridview data to an excel spread sheet. This is still working perfectly on my one webapp, but now when I copied my code to the webapp I am currently busy with, I am getting errors, and I am hoping you can spot it?
so before reading all the...
I am trying to write the following Linq (query style) in Lambda Expression so that I can chain and make my code more compact:

before I go too far, is this look right?

I was thinking about how to implement a GPS navigation for my quadcopter.
So I was writing some functions to calculate the angle between two positions (from home point to the target).
Maybe someone could review this code. Because I am not very sure, whether I was calculating the geographic posi...
