I want to learn C++

Sure: learn c++ - Google Search

Good luck,
Tyrus

Try lynda.com m8 i think they might have i aint sure but i know there have loads of good material ,

Thanks for all your suggestions. I know how to google for CPP tutorials. But I need few info about

• Whether C++ & VC++ are same?
• Which is the best editor?

you can try and visit this website Documentationtutorial/
you will surely learn from that site.

Best way to learn programming is from books. If you want to learn eg. VC++, buy a book which covers both Win32 programming and ANSI C++, read it, try examples and write programs For a start I recommend book by Ivor Horton "Beginning VC++" u can find it on Amazon I think.

If you do plan on learning C++, learn it in a vendor-neutral form. Qt is a good framework. GNU is standard. VC++ can be a pain. Choose your poison.

Have look at this book it has a very visual learning style, it might be too basic for you but it is good for the beginner:

Head first C# by andrew stellman


good luck

If you are referring to simple crawler for crawling other websites, you can develop them using PHP. No need to mess with C++. CURL functions in PHP is actually quite powerful.

Well when I was learning C++ I read this book:
Amazon.com: C++ Without Fear: A Beginner's Guide... It is just a startoff guide but I promise you will learn alot. And its on sale hehe.

Hi. May I know the actual reason for you to learn c++? If you like to do web stuff, c++ probably is a bad choice or maybe not possible. If you like to do hard core (drivers), games dev and performance driven application, symbian, probably c++ is a way to go. you can choose to do c++ for console apps or windows apps, but it is just too hard. If you want to do rad, c# is a good choice. They are almost in the same family.

can advise you better from there

Do you know all the OOP stuffs...?? did you use that in PHP...??

As far as I know PHP doesn't provide the 100% OOP stryctures,,,(actually not a singlelanguage does that..!!)...

anyway if you are new in OOP...then C++ would a real pain...

I would recommend "Complete guide to C++"...it's a good one...

I think you should first learn the basic of C...then go for C++...

As another poster said I would question your choice of language for what you need to. You should choose a language which makes you productive with what it is you need to deliver. C++ is a very hard language to master and few truly do, as Lee mentioned when you add in frameworks it adds even more complexity. For what you need you could easily go down the route of c#. My weapon of choice for over 14 years has been Delphi and that like c++ is compiled and gives me all the power of c++ with all the same low level access but without any of the headaches.

Just curious why do you want learn c++

Any reason why you wanted to learn c++? Why not Java or c#? If for VC++ GUI development, Flash/Flex, web/JSP, VisualBasic might be better options.

Try the documents an tutorials at cplusplus.com. Nicely explained tutorials.

I can recommend "Accelerated C++" if you like to learn from books

I would definitely recommend the O'reily Head First series of books. I picked up Head First PHP & MySQL and it's excellent!

I think php to c# is a much easier jump

Well If i understood you correctly your learning Cpp to build a crawler well there are many open source projects in java and python wich i think might be easier to learn.
Thou i,m not very good at any programming language LoL i learn what i need to.
And if your definetly planning on Cpp then i suggest to look into Nvidia's CUDA programming Now thats something that blows my mind every day. like if i have to restore a password form a DB encrypted in MD5 Well a normal dual core processor 3.1Ghz would do about 3000 to 5000 tires per second brute force as a CUDA enabled nvdida 9500 Gforce does way over 62 MILLION tries persecond

Check out Vidual C++ Express, it is free and it is Microsoft. They also offer training which assumes you have no knowledge all the way up to expert status.

C# is basically Microsofts version of JAVA

Hey,
i think you should start with the C and then goes towards C++.

A lot of really good advice you've received so far. If you are looking to program on multiple platforms, (such as crawlers for linux), stay away from Visual C++ or the like. You will need to learn it platform independent of a single platform, so you are not tied down to the platform's structure.

I was on the exact (I am talking EXACT, PHP to Desktop Applications) same road as you, and got all kinds of conflicting advice from one person to the next.

I wanted to develop Iphone Apps, but was restricted by Objective-C's super cryptic language structure and the Iphone's difficult interface in which to develop.

I started on Objective-C's Tutorials, but that didn't work. Too difficult.

I then went to C#, which is Window's programming language. Too platform dependent, and I couldn't migrate too easily from one to the other.

I then decided to try and start from the beginning. I tried C, but it seemed like a waste of time to start at step 0 and move one at a time all the way to step one million

I then went to c++, but all the tutorials used Visual C++ and taught you more how to use their systems vs. the programming language itself.

After all that, I was done with all of that garbage.

Finally, (here is my advice) I picked up C++ For Dummies, (corny and cliche, i know) but it taught me to code platform independent so I wasn't tied to one structure and it provided me with all the tools to jump in and start programming right away. I had my first app in, (no joke) 10 minutes.

I would pick up a copy of C++ For Dummies 2009 Edition and go over to codeblocks.org and download a copy of their FREE software and ROCK AND ROLL dude!

I hope this helps.

Writing a crawler is easy in c/c++, its probably the best way, I've written them in PHP and other scripting languages and found c the most flexible way. But c is my language of choice.

To download a page as a text file you could use something like the following code
This is for windows, Unix is a little different.

#include <windows.h>
#include <Urlmon.h>

bool DOWNLOAD_URL_AS_FILE(char * URL_NAME, char * file_returned){
if(URLDownloadToFile(0,URL_NAME, file_returned, 0, 0)){return false;}
return true;
}

if (DOWNLOAD_URL_AS_FILE("my_web_site.com", "A_TEXT_FILE.txt") == true){

//code here to open A_TEXT_FILE.txt into a string and parse out whatever info you need
//maybe hrefs, images, text, whatever

}

Pm me and maybe I can help provided its not for email addresses or credit card numbers or other shifty stuff.

Be sure to throttle the crawler so your not hitting the server to hard, A good crawler should also obey robots.txt and the META tags.

IDE wise there isn't alot in it, BCB is more of a RAD tool as you can quickly design your UI and have it produce your wrapper code very quickly, a la Delphi (which Ive used for over 10 years now)

Still think its overkill for the task in hand though!

Tons of good advice above, tho not much perspective among languages.

For a web crawler, I would use PHP and a database.

PHP is uses much of the "C" language syntax and libraries, so even the library names are the same or similar.

Although I have mastered C, I use PHP for its simplicity. C++ is enormously complicated, well beyond C. If you must use C++, the real power will be with the STL or standard template library.

The purpose of C++ is to avoid reinventing the wheel behavior. Therefore, there are gobs of libraries (functions) to learn. That's a steep learning curve for a single objective.

To understand what C++ demands of you, I recommend reading a few C++ puzzles in "How Not To Program In C++" by Steve Oualline. Just because it compiles without errors and warnings does not mean your program will run as you intended!

When programming at this level, always have a standard reference manual handy - something by Plauger, Harbison, Lipmann or Stroustrop.

BCB/RAD tools are great if you know C++ but to drill down to the debugger if you don't really understand the language may not help. C++ is intensely object oriented (OO). About ten times more difficult to master than C -- by my yardstick.

You need to get back to basics and analyse your requirements.

I am a C++ programmer with 5 years experience. PHP code is similar but there is so much design work in designing the program in C++ because of the object orientation and structure of the actual files themselves.

I couldn't even design a program unless you have first done the requirements. You don't pick the code and then decide to learn it and how you are going to do it because there is no guarantee that it will work.

By starting with what you need (the requirements) then you 'derive' and analyse the different languages and what they provide, as well as interaction with databases, and which opearating system they will reside on at the end point. ie windows or linux. You do not touch any code or start any design until after you know what you want. Its no different to building a house, you don't start with a bricklaying lesson if you need an arhitect.

So why not hire the architect? Submit a job to GetAFreeLancer and get them to create a requirements document to find out what it is that you want. They will then look at the different sites you need to interact with. Put a job in with your budget in the $30 to $250 dollar bracket and if you don't like whats on offer cancel the job, you dont' have to pick someone if you don't want to.

If you have a crawler then do they not provide API information for you to interact with. This will enable a software engineer to analyse what you need to get the job done. If you pay $50 for a requirements document then at least you know whether the job is doable or not. You could then pay a programmer to build the design.

Much quicker and easier to get it done elsewhere, by the time you learn C++ and build something one year could have elapsed.

I would have thought PHP was powerful enough. I have done some PHP but as I was C++, and used Borland C++ as my interface to C++, then I am not so up with Internet Applications. I created and wrote only desktop applications.

Hope that helps.

No, I don't do coding from home anymore. I quit when I quit my job 5 months ago. Its nice to be able to read and check code though when I pay for someone to do jobs. :-)

Good luck.

Good comment, if you don't know the language in the first place there will be a steep learning curve. Well php is kind of like c their are many differences, I would say the similarities are superficial at best. Also you will have to communicate directly with whatever OS your using, so you will need to learn a new compiler, a new language and a new operating system api.

As the poster above said contracting out the job may be far easier, but if you have the ability to stick to a project for a while you may find it rewarding but beware its a lot of work.

On the subject of learning C++

There are some really good open source tools which don't have the learning overhead of the Visual Studio Express environment. Also, the whole GUI thing can take away from understanding the core concepts in C++. It's good to note that a lot of c++ code is not of the visual kind. C++ is used to write code to run servers, write operationg systems, computer netwok software, and game engines. All of which require no gui work at all!

As already mentioned earlier Code::Blocks Code::Blocks is a fantastic IDE.
For strictly learning C++ you could check out C++ Annotations (C++ Annotations | Get C++ Annotations at SourceForge.net)
'The C++ Annotations poject offers an extensive tutorial about the C++ programming language. It can be used as a textbook for C++ programming courses.'
Also, ZinjaI - "a multi platform IDE for programming in C/C++ aimed to be used in classroom for learning C++, with strong emphasis in debugging information as an educational resource".
If you want to do web stuff with the power of C++, then you could do worse than try out cppserv : Total Knowledge: CPPSERV
It's been around since 2005, with active development, so don't be put off by its low version number.
If MS VC++ or C# is your thing, then try sharpdevelop www.sharpdevelop - SharpDevelop @ic#code
sharpdevelop is lighter than Visual Studio and easier to work with initially, it also supports VB, Boo and IronPython

On a final note, I agree with an earlier post that suggested learning Python or another scripting language as a first 'real' language. However, if you intend to become a 'real' pogrammer, it's definitely worth the effort at some point to learn c or c++. It's just a bit harder to learn C++ first, and with scipting environments it is possible to see the results of your efforts almost immediately.

Regarding platform dependancy Look at Netbeans.org they are a WYSIWYG editor for many languages including Python, JAVA, C#, VB, etc...Plus NetBeans offers some great training in both Video and Text documentation and the forum is highly active

C# is now standard in the industry. I wouldn't waste my time unless there's something really specific you need C++ for.

The best tutorial I ever seen is

Learn C++ -

Probably because when it comes to writing an OS you need to compile to native code rather than run it interpreted via IL. I would agree that its use is still probably quite high but there are plenty of other languages that dont have the learning curve of C++ and are still strongly typed, Delphi and Java are two that spring to mind straight-away. In fact with Delphi it can do everything C++ can, the only thing C++ offers over Delphi is multiple inheritance and operator overloading.

So getting back on track and has been stated above why learn c++??

if you want to learn C++ i suggest you take a course there are parts that you will need someone to help you and understand certain code.. believe me.. there are a lot of good books but a teacher is better !

I second that, can you find a local course? It might allow you to get your feet wet in a supported environment & decide if you really want to get stuck in? It's quite a large language to learn and to really benefit from more advanced features you'd need a good bit of experience with it.

No Matter what you use, make sure you stay platform independent. 3/4 of all books that teach VC++ teach you how to build the visual stuff before the code and don't focus nearly as much on the language itself.

Stay independent. Don't get pinned down into one operating system. Especially Since Google's new Operating system, (Chrome) will be coming out next year. GET READY!!!

I hope this helps.

I am also a php guy and also way to learn C++ but i have not read any good tutorial yet.

Thanks

I have basic knowledge in C++ but its been years I am not doing program in this language, so I too want to re learn the language, with the blogger replies I got lots of resources. Thanks

Well, since that you're already a programmer, it will be easy for you to learn new language. There is a lot of free tutorial you can find in the net. Good luck.

I would suggest you read this free book from Bruce Eckel. You can search "bruce c++" on google.

I love C++. It is very lean (sometime a bit mean also). I would suggest you start with fundamental of C++ such as object oriented. It is difficult but after you can understand the concept, you can apply it to many programmin language.

HTH

Hey man. Do you have a good foundation in data structures? If not, make it a good one, next is OOP, then the actual language (C++). Proprietary language like VC++ has an advantage if you are targeting only a single platform, if not, you can use Eclipse as the IDE and MinGw (you can choose other compilers) as the compiler. Ok?

As of now, i am a little bit disappointed in java because APIs are limited especially if your application requires a vendor specific execution. Been in java for 4 years now, especializing in modularization using OSGi and J2EE. Now i am starting to review my C language knowledge. Hehe.

According to me. U first learn C And tahn after C++ . If u are a programer in php than i suggeted to Learn C which is foundation of Programing .You can take tutorial from the W3school.com of C,C++. Best of Lucky.

i think Wrox Ivor Hortons Beginning Visual C Plus Plus 2008 is the best book
for learning C++

i can teach you c++ can you teach me php in return

Read This Book - LET US ''C'' - YASHWANT KANETKAR. Learn C first and then move on to C++

STOP!!!!!!

You are going to learn C++ to create a crawler?

No! No! No! No! No!

and no again!

The only reason you need C++ for your own tools is if you are writing system level software, drivers, or accessing hardware. For IM purposes, you will not.

Sure people have been helping you out, they do a quick google and link you to an article. That doesn't really help.

C++ is an entirely different beast than PHP. You will waste your time and effort.

What should you do instead?

Instead you should pick a language that will work with you rather than against you such as Ruby, Python, Perl, or Java.

Here is the breakdown:

1. Ruby - Hands down the best language for tool development. Ruby gets out of your way. It is the easiest language to use. Is not a pain in the ass about data types, syntax, type-safety, and all the things that suck in C++. Runs on all operating systems and your code is entirely portable. It is interpreted so your same script will run without modification anywhere. I use it to make all of my own crawlers, scrapers, SEO tools, and more. It is great for screen scraping. Highest recommendation!
2. Python - Python is another awesome language. Gets out of your way. Strong library base. Interpreted, runs everywhere. Would recommend as well.
3. Perl - Perl is awesome as well. See Python description. VERY strong library base. I would recommend Python over Perl since it is easier to learn.
4. Java - Java is very similar in syntax to C++. Very strong library base and can incorporate C++ dll's easily. Strong visual development language.
5. Visual C# - Access to Microsoft .NET. Very similar in syntax to Java. Great for Windows only application development.
6. Visual Basic - Don't waste your time, it has been replaced by Visual C#
7. C++/Visual C++ - The longest way to develop a program. You will be confined to Windows if you use Visual C++. You will run into many issues as it is just the nature of the language. It takes so long just to do anything that it is a waste of time. I love C++. It has it's place. IM is not the place for C++. Everything you want to do would be done quicker by one of the above languages.

If you need a crossplatform GUI then don't go for Ruby.
This is what I was able to do in Ruby in a few hundred lines of code.

1. Scrape a certain page for keywords
2. Perform SEO analysis on keyword
3. If the competition is weak it will find content from Youtube, blogs, and news
4. Submit to a blog via Wordpress RPC
5. Modify the All-In-One-SEO SQL data for that post to get the best on-page optimization
6. Automatically submit the bookmark to many social bookmarking services for backlinks.

A few hundred lines. In C++ that would take a good programmer at least a week. A decent one, weeks. I came up with the idea at 10PM one night pulled an all nighter and had it done by the morning. That is the power of dynamic, out of the way languages like Ruby and Python.
