hi to all. can you give me somme hints.

first i will like to say Hello @

naw im a total new to any caind of Programing leangue
but i will like to ask a few qestions on that .

well i will like to learn this but i do not know what i need
im intrest in Multimedia genelaly
and will like to know if there is an Book that
i can by and read.

what i will like to do is build softwares for diferent
hardwares, but as i sayed im a begginer and do
not know what i need of softwares and
most importend of where to beggin with.

thanks in advance for any replay
and sorry for my Bad English.

You will need a text editor so that you can write source code, and you will need a compiler, which is a program that converts your source code files into files that can be run by your computer.

Sometime you can get these tools combined into in what is called an IDE. For C / C++, Dev-C++ is an excellent and commonly used choice. It is also available free of charge.

The non-forum part of this website can give you more information about getting started. It has information about different compilers / IDE's, how to get them, and it also has tutorials that you can use to teach yourself the language.

cindly thank you

i will have a lock round and see if i find any thing

and will you please tell me wich is the
The non-forum part of this website

thank you

hi

well i have taken a lock a round in the forum
and to tell you the truth it is all Greek to me.

i have not found anything on the subject

so i will realy like to know if there is any
good book obout Cryptografy

im verry apasionated with the DVB-S (digital video broadcast by sattelite)and will like to build softwares for (resivers,senders,cards,cams,and other programers)

i will need all the help i can gett to start :)

will be very happy for any hints :) :)

and if any of the Moderators here think that
im in wrong section or breacking the rules just
move my post.

like sean already said, get a book(s) and compiler/IDE. once you tell us what compiler you're using, we'll be able to help you build your first program. from there on, you should be able to follow tutorials with (or without) a little help.

for the time being, forget about cryptography. that's very heavy, in-depth stuff there. I'll teach you XOR encryption, but that's about all, and that's definately not in the cards for the first few lessons.

here's what you do:

1) go to http://www.bloodshed.net and download dev-c++.
2) run the program, and in the text area that appears, type the following:

Code:

---

#include<iostream>
int main()
{
    std::cout<<"Hello World"<<std::endl;
    std::cin.get();
    return 0;
}

---

3) press <F9>
4) come back and tell us what that does
5) I'll tell you what to do next when you get here.

This is likely way over your head programming wise, but the Handbook of Applied Cryptography is available free here. It's still possible to grasp the idea without understanding the code.

hi and thank you for the help
well i am using Dev-C++ 5 Beta 9 (4.9.9.1)
and i have run the code you have in your post
and what happens it is that after the (f9) there is three files wich
are saved wich are( Makefile.win,Project1.dev,Untitled1.cpp)

thats so far i have comme :( what could i do next please

well i know that cryptography is havy staff but isn,t that something i must learn in DVB-S

XOR is some thing i must to so im very intrested in any help
if you could help.


@ Govtcheez thanks for the link


bobi

okay, assuming that you actually 'ran' it and it worked the way it was supposed to (display "hello world" in a console window), it's time to tell you what that code is actually doing:

Code:

---

#include<iostream>  //pre-written code for you to use

using namespace std; //this allows you to skip the std:: before cout,endl, and cin.get()

int main() //this is where the program starts. always.
{
    cout<<"Hello World"<<endl; //cout is the standard output for C++, and endl flushes the stream
    cin.get(); //get() is a method commonly used to take in input from the user
    return 0; //used in functions, which you'll learn about later - you can ignore this for now
}

---

if you need further clarification on that, post and I'll answer your questions. now you need to go and try out some tutorials. the tutorials on this site are alright, although most won't work in your compiler because the tutorials are old.

I would try using these tutorials: http://www.cplusplus.com/doc/tutorial/

edit: those tutorials are old too... hmm... just try using either those tutorials or the ones on this site (cprogramming.com probably has better tutorials). if (when) you come upon problems, come back and post and I'll help you get through them. eventually you'll learn about the problems you're getting and you'll be able to fix them on your own...

Ive been lurking these forums on and off for a week. I'm already glad I found this site. I have been interested in learning C++ for a year or two. I already know leaps and bounds more than what a book was trying to teach me.

I'd been scratching my head trying to figure out what namespace std; did through the in site tutorial. When I saw you put std:: I was really thrown for a loop. I either missed it or it wasn't in the tut. Thanks for taking the time to point it out.

I'll take this advice too. I've been reading the site tuts over and over while worrying about their content. Thanks again.

so i will realy like to know if there is any
good book obout Cryptografy

Once you have learned a good bit of programming and are ready for it, Modern Cryptography by Wenbo Mao is a very good introductory cryptography book. That said, it doesn't focus on code, but methods and some of the theory behind cryptography.

yeah, most tutorials don't bother telling you what it does - they just tell you to put it there. it's because they're afraid of 'overloading' you with information. IMO, just a small, temporary explanation is alot better than 'just do it because we said so'

hi agein

well i ahve been reading a bit around in the forum
and to tell you the truth nothing rings a bell for my head
not yet at least all seams Chinese for me :(

and do you think it will be better for me as a TOTAL begginer
to have a book and read or?

last i will like to know if it will be any good for me to
by both books for the C++ and Cryptografy

and wich is bets for me as a begginer. :confused:


thank you for the help

Start with basic programming in C or C++. When you actually understand that, then you can move on to other things. Jumping right into cryptography is a recipe for failure.

thanks for the advise my friend

well i think i must do a lott of reading firs of all
and se from there what i can do and if it is somme dificult thing
for my brain ;)

maybe in this case, but think of it this way: what about a math professor that is trying to learn a little programming on the side... cryptography may be easier to learn than the implementation of that cryptography in C++ to them...

just playing devil's advocate :D

Cryptography must be a recipe for failure because I've never even heard of it!

Anyway, bobi, try the book in my avatar: C++ For Dummies. It's taught me alot of the language. If I can do it, so can you (heck, I'm only 14 and I can write functioning programs).

maybe one day i will be as good as you guys are
and thank you for the help you give to ppl like me
