First, I want to say that this is just an learning exercise and I do not intend to use this in production.
I wrote a small application in Golang with two functions: encrypt(plaintext string, password string) and decrypt(encrypted string, password string)
The encryption steps are:
Generate ran...
If I have a oneliner in C such as
size_t maxSizeOf(const char *s)
{
return strlen(s) > M_MAX_SIZE ? M_MAX_SIZE : strlen(s);
}
would it be better to have a macro defined such that
#define MAX_SIZE_OF(s) (strlen(s) > M_MAX_SIZE ? M_MAX_SIZE : strlen(s))
or would it be better to have

Write a program to print all prime numbers from 1 to 300. A Prime Number can be divided evenly only by 1 or itself. And it must be greater than 1.
One thing lead to another and eventually I wanted to know the "proper" way of writing the permutation generating function in C#. Below is my code for generating permutations. This will go into an internal library, so the calling context is really generic. Expected calling is in a single-threaded ...
As a self taught developer I never did any of the Project Euler problems, so I decided to just start with Problem 1 which states
If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
Find the sum of all the mul...
Hi every one I recently implemented subset of ustar archiving utility as my first year programming one project and I would like to get it reviewed and if any one have anything to point out ..

#include <sys/stat.h>
#include <unistd.h>

I'm working on a little vocabulary trainer application in Java. My plan was to understand how to properly organize the Java Swing code, ideally using the MVC pattern.
My concerns are:
The controller registers ActionListeners to the view. These ActionListeners contain the logic to decide if the...
I've just written a code for for generating all permutations of the numbers from 1 to n in Java. It seems to work, but I think it's a bit more complex than it needs to be. If someone can advice me how to simplify my code, I will be very thankful.
Here's the code:
import java.util.*;
public cl...
This is a class that reads content from a CD-ROM:
ISO9660 content : descriptors, path tables, directory records (i.e. the file system)
sectors in 'user' mode and 'RAW' mode
files in 'user' mode and 'RAW' mode
(entirely written in C#, uses DeviceIoControl and SCSI MMC-3 commands)
Since it is ...
I am very surprised why this is not working. It is a very trivial array initialization process. What went wrong here?
#include<stdio.h>
int main(){
int a[5] = { 1, 0, 1, 0, 1 }, b[5] = { 0, 1, 1, 1, 1 };
int c[6], i;
int carry = 0;
for (i = 0; i < 5; i++){
int temp = a[i]...
Inspired by this question I decided to write an alternative that uses polymorhphism and a Factory pattern. The code works for the subset of implemented types, namely BYTE, WORD and STRING but I have a few concerns:
I'd like to get rid of the big ugly switch in the TLVFactory.
Is there a way ...
This is a data structure that supports the push(), pop() and isEmpty() operations and returns the least element on every pop(). In a sense this works like a PriorityQueue only in O(n) runtime against the O(log n) runtime of a PriorityQueue.
This is my implementation,
public class SortedStack<T ...
I create a class that holds an EAN13 code. This class is atribute of a Product class.
In the Ean13 class the String that represent the EAN code is passed as parameter to constructor and the validation is performed in the constructor. I create some util methods in that class, like sumEven, sumOd...
I've been told that using God objects at all is a Bad Thing™
In object oriented languages, God objects know all, they control too much. I'm trying to build a game (or for the scope of this question a generic app with a gui) and I'm using a Main object that holds all the other objects needed to m...
