c++ DoublyLinkedList

Thu, 17 May 2012 23:19:53 -0400

I have been learning c++ recently and I am trying to create a linked list using template classes and methods. I am sure I am not doing it right, but I really cant find a tutorial that explains how to do it in my particular case. Can someone guide me in the right direction on how to implement this the correct way. Thanks in advance.

[code]
#ifndef NODE_H
#define NODE_H

#include

template
class Node {
public:
Node(T object);
Node(const Node& orig);
virtual ~Node();

private:
Node _next;
Node _prev;
T* _object;

friend class List;
};

/*
* Implementation of the Node class
*/
Node::Node(T object) {
_object = object;
_next = NULL;
}

Node::Node(const Node& orig) {
}

Node::~Node() {
delete _object;
delete _next;
delete _prev;
}

template Node Node::getNext() {
return _next;
}

template Node Node::getPrev() {
return _prev;
}

template T* Node::getObject() {
return _object;
}

#endif /* NODE_H */

[/code]

[code]
#ifndef LIST_H
#define LIST_H

#include
#include "Node.h"

template
class List {
public:
List();
List(const List& orig);
virtual ~List();
void front_insert(T object);
void tail_insert(T object);
T* find(T* object);
private:
Node _head;
Node _tail;
};

//make the head and tail point to each other
List::List() {
_head->_next= _tail;
_head->_prev = NULL;
_tail->_prev = _head;
_tail->_next = NULL;
}

template T* List::find(T object) {

}

template void List::front_insert(T* object) {
if(_head == NULL) {
_head->_next = new Node(object);
}
else {
Node* temp = _head;
while(temp->_next != NULL) {
temp = temp->_next;
}
temp->_next = new Node(object);
temp->_next->_prev = temp;
}
}

template void List::tail_insert(T* object) {

}

#endif /* LIST_H */

[/code]
I have done most all of my programming and in Java and Objective-c. I want to migrate to more powerful languages so I am a complete noob at c++.

fifa12 ultimate

c++ streams

Fri, 10 Feb 2012 10:46:51 -0500

I am current writing a c++ program will write a file to disk at a sector that you choose. I am using an fstream and was wondering why it would not let me run when i used it fstream as a pointer. Can you explain this to me. I am farily new to c++.

FILE.H
[code]
/*
* File.h
* This file is designed to hold characteristics about the source
* that you are writing to disk.
*/
#ifndef FILE_H
#define File_H

#include
#include
#include

class File {

public:
File(std::string path, std::string target);

//set the path to the file
void setFilePath(std::string path);

//get the size of the file in bytes
int getSize(void);

//get the file type
std::string fileType(void);

//return a representation of the file a string
std::string toString(void);

//set the path of the target disk
void setTarget(std::string targetPath);

private:
std::string filePath;
std::string targetPath;
std::string file_type; //binary, hex, text
int size_in_bytes;

std::fstream inputFile;
std::fstream outputFile;
};

#endif
[/code]

This constructor worked fine
FILE.CPP
[code]
/*
* Implementation of "File.h"
*/
#include
#include
#include "File.h"

using namespace std;

File::File(std::string path, std::string target) {
inputFile.open(path.c_str());

if(!inputFile.is_open()) { //test to see if the file opened correctly
cerr << "open error";
}

filePath = path;
}

void File::setFilePath(std::string path) {
filePath = path;
}

int File::getSize(void) {
return size_in_bytes;
}

std::string File::fileType(void) {
return file_type;
}

std::string File::toString(void) {
std::string retval = filePath ;
return retval;
}
[/code]

The program would still compile but would not run exit status 1
[code]
the only difference in my file.h was
std::fstream *inputFile;
std::fstream *outputFile;

FILE.CPP
/*
* Implementation of "File.h"
*/
#include
#include
#include "File.h"

using namespace std;

File::File(std::string path, std::string target) {
inputFile->open(path.c_str());

if(!inputFile.is_open()) { //test to see if the file opened correctly
cerr << "open error";
}

filePath = path;
}

void File::setFilePath(std::string path) {
filePath = path;
}

int File::getSize(void) {
return size_in_bytes;
}

std::string File::fileType(void) {
return file_type;
}

std::string File::toString(void) {
std::string retval = filePath ;
return retval;
}
[/code]
thanks in advance

Hi world famous RedD3ath here. Assuming my world is the only world you live in. Here is a little about me with out boring yourself to tears. I am a pentester, a self-taught developer, and a dire lover of technology and knowledge itself. Ever since I was born I�ve always been a �Curious George� I guess you could say. Moreover, I am a CCNA (Cisco Certified Network Associate) and currently training for more certifications such as A+, CISSP, and CEH and working towards a Bachelor�s degree in Information Technology. In the meantime, apart from writing various technology blog posts I like to spend my time studying about Hacking and Computer languages as well as spoken languages such as Hebrew, Greek, and Aramaic. I also read a ton books mainly informational and computer books but I own a few fiction novels as well. My hopes in future are that I aspire to work as a Security Analyst or Systems Administrator. As for ICV my hopes are to conglomerate with a circle knowledgeable people in my circle of collective knowledge. Where you learn from me and I learn from you. My motto is knowledge and boy do I love to learn. I soak it up. Moreover, thanks to ICV for such an awesome forum and the knowledge shared here. I look forward to meeting some of you.

Hi.

I'm new at this. I'm also kind of old. I am here because my computer was hacked. When it happened I was fortunate enough to know that something was not right. I paid a guy $100 to fix it. While he was fixing it he turned me on to 1337 h4xor h4ndb00k. I want to be more knowledgeable about computers. Not just my computer but about the world of computers/coding/etc. in general.

Yes, I've rtfm. I haven't started any coding projects yet because I am still rtfm. When I finish the book I am going back to work on the projects. I'm hoping to further advance my learning through this forum. I'll try not to do/say any stupid shit.

FWIW, I am a classically trained musician (composer/double bass). I love metal.

And it's back up. Sorry.

Need suggestions and advice

Hello everybody,

It's been a while , isn't it.I am studying and I was thinking of starting some kind of project, so I decided I would make a 'website'.So skills I have are very low for instance I know HTML, Basic CSS, Very basic JavaScript.And I know nothing of networking.

Still I am adamant on starting this project so I can learn while write scripts, so does anyone know any book which guides in such a direction or any website which has detailed guidelines.

And does any one know a free server-service where anyone can upload their sites...etc? I am trying to learn by writing , so I hope all my friends here would advice and suggest me with important things which I should keep in mind.

Suggestions and constructive criticism are welcomed.Thank you.

Regards.
