i have a .txt file with a bunch of numbers(1...99), millions of them, and i would like to make a program that recognizes patterns(if exists, i don't know) of numbers in this file. What will be the starting point? How could i do that? I read i could do that with Neural Network. Is there other way?

We never really had a thorough discussion yet about if-else statements and while.. but our teacher already gave us a difficult assignment..
We should write a program the accepts a number , n, and displays the first n values of the number series:
the pattern to be print was like this 1 1 2 3 4 5 8 7 16 9 32 11 64 13...
alternating odd and even numbers using while and if-else statements
if you input n, the output will print only until 1 1 2 3 4 5 8 7
I've been coding for about 10 years now and it just got to my mind that I would like to learn about how I can create speech recognition software. I am mostly interested in doing this from ground 0 not because there are no other libs I can use, but it's more of an interest to me.
grasp this new and magnificent feature that's becoming more and more used nowadays.
My preference would be coding in C++ (more because of OOP that's why not C) and I don't really like Java.
I know what I'm getting involved in but I am thrilled and willing to go all the way to achieve my goal.
create a artificial neural network for character recognition. URL.....Background:
- I have a good understanding of C++ and Assembly code and currently working on my java skills.(PF1, PF2, Paradigms, and microprocessing classes)
-I've programmed microprocessors(PIC) and will be using a PIC32MZ processor to operate the camera data collection and ANN operation. Currently, I plan to program this PIC in Assembly and C since I do not know if C++ will work on the microprocessor hardware.
All day long I tried figuring out how to setup VOCE [URL] ....
I am using VS 2010.
What I did:
* Downloaded JDK
* Downloaded the VOCE, extracted and put in c:
* Opened VS and in properties->Vc++ Direcotories:
* In Include Directories i added: C:voce-0.9.1srcc++, C:Program * FilesJavajdk1.7.0_45include, C:Program FilesJavajdk1.7.0_45includewin32
* In Library Directories i added: C:voce-0.9.1lib, C:Program * FilesJavajdk1.7.0_45lib
ALSO: I didn't get what i suppose to do with C:voce-0.9.1lib everything there * is winrars

I'm trying to output a pattern using loops. The pattern is a plus symbol made of 3 rows of 5 x's followed by 3 rows of 15 x's and finally 3 rows of 5 x's.
I can get the program to output all 9 rows with 5 x's but I don't know how to do the 3 rows of 15 in the middle. I have tried a while loop and also an if statement but nothing seems to work.

I am looking to write a program that, given a particular word, looks at a plain text document and gives a list of words that appear within x words of the given word along with a count of how many times it appears.
Do I need to use regex to do the pattern matching here? Is there a particular data structure that I should use that is particularly suited to a task like this? I don't want to reinvent the wheel, it seems like there should be libraries that would already do this sort of thing but searches have turned up nothing.

I am looking into some design pattern which works for validation.
I thought about using strategy but not sure whether its correct or not
Any design pattern allows to describe operation like the following.
MyFunctionObject f;
//Init f...
MyFunctionObject g;
//Init g...
MyFunctionObject h = f(g) + g;

I'm interested in design pattern which permits to model this kind of structure, if there's of course...
I have a class buffer, which holds a std::string as member, and a socket_receive function:
struct buffer {
string data;
buffer() {}
buffer(buffer& b) : data(b.data) {}
};
buffer socket_receive() {
buffer tmp;
tmp.data = "1234";
return tmp;
}
so when I write
buffer b = socket_receive();
there is a copy constructor, and the tmp variable is constructed and destructed, is there anyway to improve the performance?
I tried the new c++11 move(), but seems even worse, I must be doing wrong with move(), but I don't know how.
#include <iostream>
#include <string>
#include <ctime>
using namespace std;
struct buffer {
string data;

So, I'm going to write a recursive function for a asterisk pattern but I'm stuck figuring out how to create a stopping case for it, better yet, I'm unable to describe the pattern completely.

( - represent white spaces )
What I've been thinking:
* Every odd row has 1 * with 1 incremented white space
* Every "pair" of asterisks equals 8 total (EX. 8 one pair *'s, 4 two pair *'s, 2 four pair *'s)
Unfortunately, that's all I got. how I can represent this as I function. Once I figure out what my stopping case should be, I think I can do the coding on my own.
I have implemented the IRepository and UnitOfWork Patterns in my project and I have made a little tweak in the UnitOfWork pattern .
public class UnitOfWork : IDisposable {
private DataContext m_Context = new DataContext();
private bool m_disposed = false;
#region Repositories
private GenericRepository<Product> m_ProductRepository = null;
private List<object> m_RepositoryList = new List<object>();
#endregion
[Code] ....
In my UOW class I have the public property ProductRepository. Now my idea was instead of creating a public property for every repository that I have, I created the generic method GetRepository<T> to dynamically create repositories.
Do you think that this change will have bad side effects. I think that it will improve the maintainability of the code.
I have a string like "THIS::IS::THE:EXAMPLE::STRING"

this is a singleton pattern first,it doesn't matter, why I could delete this pointer twice?because the gcc compiler?That mean in the surface, "delete pInstance1;" this movement just mark the memory pInstance1 has been deleted but not real?does any one encounter this phenomenon?

I need to design an interface(a function prototype) that takes an argument which is used to pass information.
The information can be passed by independent modules and third party softwares and hence can vary today and in future.
Basically, the function interface(arg1, info)caters a niche service to many independent applications and needs to process based on requirements passed by applications in the argument(info, in example).
I am looking for a design pattern for the function parameter - info.
Should I use a void pointer that can be casted to respective application specific class in the function ? will this be a good C++ design ?
or should I take this parameter to be a pointer to a generic abstract class that points to the respective application specific specialization ?
Do we have some design pattern to address this so as to handle other unforeseen challenges ?
The code below runs correctly (feel free to compile and run it yourself to see what it does). But when I turn Object abstract by uncommenting the line
virtual void foo() = 0;
It obviously won't compile. I want to use a copy constructor rather than restoring one data member at a time because I'm assuming that Object will have many, many data members (and also want to avoid extra responsibility when new data members are added to Object). Of course, using a pointer to Object in Memento will defeat the purpose of taking a snapshot.

I am trying to write a program that will make a pattern of stars. The last line is really tripping me up. I have to make the code only using the printf("*"); printf(" "); printf("/n"); statements once. I want to accomplish this with a for loops and if statements.

* * - 4 spaces before *
* * * - 3 spaces before *
* * * * * * - 0 spaces before *

here are the links on codepad [URL]
I think my first approach is way off. But I think I am on to something in the second link. I'm trying to print the "*" and extra 2 times on the fourth line. In the second link the compiler appears to be ignoring the || operator. Is my syntax incorrect in the second attempt? How should I change my if statement to make this pattern work?
In code, I need to transform these values:
256 becomes 0

I need to write a c program that can receive signals and recognize a certain pattern (SIGUSR1, SIGUSR2, SIGUSR1, SIGUSR2). once the pattern is caught the program terminates itself.
I am able to send the signals to the program from a different process, but I am unsure on how to get the signal handler to recognize the pattern. here is what i have so far:
Code:
#include <signal.h>
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <unistd.h>
#include <stdlib.h>
sig_atomic_t sigusr1_count = 0;
sig_atomic_t sigusr2_count = 0;
[Code] .....
I just need getting the program to be able to catch that specific pattern.
