I took a little time and wrote the following code to produce enigma encryption. I don't normally write code in C so I would like to get feedback on the way it has been structured and any issues a more experienced C programmer might spot in the way I used structs, command line parsing, and the i...
What does virtual identifier means in c#?
Or What is the difference between:
public virtual string Type { get; set; }
And
public string Type { get; set; }
Thanks
Quite sometimes back i had written an Android application which simulates the path of a pendulum. You can also have look at the complete discussion in my Technical blog at http://som-itsolutions.blogspot.in/2012/06/android-graphics-and-animation-pendulum.html
Here goes the code for the same. Pl...
I'm new in programming. So I've developed this code in C++ which works fine, but there's a problem.
First, check the code.
#include <iostream.h>
#include <conio.h>
void main() {clrscr();
float num;
float sum=0;
char ch;
do
{do
{cout<<endl<<"Enter number:";
cin>>num;
sum+=num;}
while (...
My question is about arrays for this program.
So far I have this
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
const int ARRAY_SIZE = 15;
int numbers[ARRAY_SIZE];
int count = 0;
ifstream inputFile;
inputFile.open("p6.dat");
while (count < AR...
There is a simpler solution. Consider this logic:
if it's the first column, the value is always 1
if it's the last column, the value is always 1. (You can check this based on the row!)
otherwise, it's the sum of the value in the previous row previous column + previous row same column

You should read more about how JavaScript works, especially variable hoisting.
if (window.event) {
var charCode = window.event.keyCode;
} else if (e) {
var charCode = e.which;
}
Here you are declaring two variables with the name charCode. But you want to declare it only once and then i...
I am checking for particular keywords in a string, and then changing the forground and background colors of substrings based on the keywords. Following is the snippet for checking the background code:
if(string.contains("[30;42m") || string.contains("[31;42m") || string.contains("[32;42m") ||

You can do it a little more generic but I'm afraid you still have to test each.
I don't know if your case is always changing to green or not.
If not I suggest the following enum :
/**
*
* @author chillworld
*/
public enum ColorMapperEnum {
GREEN("[30;42m",Color.GREEN) ,
RED("[31;42m"...
I've written some code today to be able to dynamically execute prepared statements/parameterized queries.
I need a fresh pair of eyes to look through my code for eventual performance gains that can be made.
I've tested the code on up to 20 parameters without problems.
For formatting I use this...
Boolean usage:
You have waaay too many explicit boolean flags, which are only a implicit variant of some others.
private boolean leftToRightMovement = true;
private boolean rightToLeftMovement = false;
private boolean atTheMiddlePositionWhileLeftToRight = false;
private boolean atTheMiddlePosi...
Here is my controller code. I try to create application with MVC N-layer pattern. I asked my buddy for shot review, and he said "You should separate logic from controller".

In my program I call "granularity" the "minimum step" for number. For example if "granularity == 4" then I only work with numbers "0, 4, 8, 12 etc." (so normal interger has granularity == 1)
I need a function to round integer number to certain granularity. So for example if granularity == 3 I w...
I am fetching data from the database using entity framework and linq queries. I am wondering about the performance of getting data.
Here is my code. I just want to check that a Well exists in database or not. Database table has 15 columns and number of rows are unknown.

@ratchetfreak's comment is correct, expanding on it here a bit:
AsyncTask is the class to use (or rather, extend and use your subclass-implementation, as AsyncTask itself is an abstract class).
You should use AsyncTask for performing operations that otherwise would block the UI-thread and thus ...
I started to learn rust last night. Given its parallelization capabilities, I thought a good starting point would be porting my C++ AI for 2048 to Rust.
This is the function implementing the shift of one line (from high to low indicies) of the 2048 board, ported quite verbatim from C++. It is s...
