Ask YC: C++

Folks, I am a Pythonista, and need to learn C++ in a hurry. I have almost negligible familiarity with the language. In a months time I want to be able to hack basic apps in the Symbian C++ environment. I am looking for suggestions for good books for C, C++, STL and Symbian. Please let me know what you think is the best course of action. Also any advice from your experience is appreciated. PS: What do you think of C++ as a language?

JFred 19y ago
I don't think you can become a proficient C++ coder in one month unless you're really, really smart and unusual. Maybe not even then. Although, it depends on what you mean by "Hack basic apps", doesn't it? If you're working on existing apps then you'll need to know the same subset of the language that the original programmers knew. If you're going to write apps from scratch you might do very well by starting only with the Symbian programmers documentation, if it's good. Beyond that, just learn C and use C++ as a "Better C". If you can avoid using classes and templates you can start quicker.

Symbian C++ is a different beast. It is heavily design pattern oriented, so it is a good idea to ger comfortable with things like active objects,publish and subscribe, client-server, factory, singleton, etc, etc... Obviously, get the SDK, demo apps and start experimenting with it, as you would do with any other technology. Do you mind if I ask why you need to hack in Symbian C++?
- davidw 19y ago
  Yeah, I'm curious if you're sure you really need Symbian, or mobile or...? I haven't heard pleasant things about Symbian myself, but have no direct experience.
- kashif 19y ago
  Thanks for the response. Need to develop a mobile app for a client. PyS60 apps get really heavy because the interpreter needs to be added with the app.
  - hcho 19y ago
    Wouldn't J2ME do it for you? Less of a learning curve...

  - Zak 19y ago
    How about embedding Lua and writing most of your app in that? That's what game developers usually do when they get fed up with C++. Lua is much lighter than Python and intended for embedding in C/C++ apps.
    - kashif 19y ago

This is the book I learned Symbian/C++ on: http://www.amazon.com/Developing-60-Applications-Developers-Developer/dp/0321227220/ref=pd_bbs_1?ie=UTF8&s=books&qid=1208352191&sr=8-1 http://www.amazon.com/Developing-60-Applications-Developers-... It's a bit out of date and it focuses on Nokia's application framework (Series 60). It should be enough to get you writing basic applications though. If you're going to stick with Symbian, don't worry about C or STL. They don't use them. I assume you're going to be using the more recent Symbian 9. Unfortunately, I don't have any books to recommend for this version. You'll need to rely on the Nokia/Symbian docs for Symbian 9 specific features like Platform Security. Since you're new to C++, I'd recommend following Symbian's naming conventions religiously. They were very helpful when I was a C++ noob just starting out. I haven't worked on Symbian in about a year, but if you have any questions, drop me a line (email's in the profile). I'll see what I can do.

  This is great advice. Platform Security is a system unto itself and language-neutral. In fact, Symbian-C++ is quite an old dialect. Series-60 is by far the most prolific Symbian-based platform and well worth understanding even if you are not programming to those APIs.

But I hate C++/STL/Boost far less than I hate C++. The STL and Boost make C++ feel almost like statically typed python, (while occasionally driving you mad with pages full of template errors).

Some people insist on programming C++ like it is c. I.e., they will build an array (hoping it's big enough, sometimes they will even error check if it's not), cast the edges to int's, keep track of how many array members represent edges and how many do not. If you do that, your life will suck.

allenbrunson 19y ago
i see a lot of people bashing c++ here, and rightly so, i guess. its evolution was too heavily influenced by backward compatibility and pleasing too many masters, in my opinion. i still like to program with it anyway, because i use my own restricted subset. if you're in a hurry, maybe you should learn just plain old C, which is a lot simpler, and then sort of quickly rush through classes and other stuff specific to C++. i'm kind of in the same boat. i'm teaching myself ruby, so i can eventually become an RoR programmer, and join all you hacker news types in the web 2.0 world. before that, i taught myself objective-c, so i could do cocoa programming on the mac. there's some surprising similarities between ruby and obj-c that i wasn't expecting.
tx 19y ago
C++ feels like a Japanese sportbike for small projects: your code will run crazy fast and it's easy to kill yourself if you're not good enough at it. When your project grows beyond a certain size, C++ starts to feel like early soviet ballistic rockets: plenty fast, but a nightmare to maintain while on the ground, take forever to prepare to launch and can explode at any moment while in flight. I used to love it, up until I bought a Pentium-III 800Mz with 512MB of RAM somewhere around 2001.

Effective STL Programming by Meyers is probably your best bet for comprehension and fluency. Stroustrop is surprisingly good as a walkthrough of the language itself. Modern C++ Design by Alexander Alexendrescu is the best advanced book.
copenja 19y ago
First: Accelerated C++ by Andrew Koenig and Barbara E. Moo -Great book aimed at absolute beginners written by top of the line experts. Koenig worked at AT&T and was a major player in the C++ standards committee. Second: Effective C++ by Scott Meyers -This book is spectacular and will take you from beginner to the next level. It is very well written and an easy read. More Effective C++ and Effective STL are also good. Reference: The C++ Programming Language Bjarne Stroupstrup -This should be your reference book. If you want some Guru level references I can list a couple more advanced books if your interested...
- kashif 19y ago
  Ok. This sounds like a plan. Thx
  - deepsea 19y ago
    Yup. It's a very good plan. The key is Accelerated C++. Just lock yourself in a room with a computer and a coffee machine and get through that book. It's short, well written, and contains examples throughout that you should be typing in as you progress through the book.
- anupamkapoor 19y ago
  i think "ruminations on c++" by the same authors i.e. andrew koenig and barbara moo is also very good. if you can get your hands on "barton and nackman", its nice too. imho, the fundamental problem with the language is the principal of maximum-surprise. what you don't know can really hurt you...
ilitirit 19y ago
I love C++ There are so many crooks and nannies, pitfalls and gotchas in the language that most people either give up, or they take the time to learn to do things the "right" way. I fall into the latter group. However, I absolutely despise the C/C++ compile/link model. And I hate STL errors, or any sort of error that arise from the incorrect use of templates. And header files need to die. I learnt most of the C++ I know from tutorials on the Web.
palish 19y ago
If you would like to do something significant within a months' time, learning C++ by reading a book is the worst possible course of action. Start by following along with some basic C++ tutorials. Once you're comfy enough, start implementing your own small applications. (Write a program to accept a sentence from the user and print it out. Then write a function that takes two strings and returns true if the two strings are anagrams. Keep thinking up small apps.) It is my opinion that you must avoid learning STL and Boost if you want to be productive within a month. Both libraries have enough quirks that it takes a significant amount of time and experience to use them correctly. For example, you don't need the std::vector or std::list containers. Simply allocate a sufficiently large array to hold your items, then allocate a larger array when the first one fills up. A std::map container (a dictionary) is also not needed if you're tracking a small number of items. Simply loop through all items until you find the one you're looking for. Basically, start actually writing code as quickly as possible. If you feel like you're burning too much time trying to understand one tutorial, move on to another one. But make sure at the end of each day that you can look back and say, "I wrote a lot of apps today and I feel like I learned a lot." Most importantly, don't be afraid to throw your old code away once you have a better understanding of how best to solve the problem. Implementing components as quickly as possible is the key to productivity. Rewriting your old code is the key to not making a mess. Contact me at palish@gmail.com if you have any questions along the way. I'd be happy to help. I'm a self-taught graphics programmer, so I can relate to how scary C++ can seem at first. Try to implement each application in the simplest possible way.

  I have to disagree with your advice to avoid vector and map. If you're used to python, you probably have a very list- and dict-centric method of programming, and you are probably not very familiar with explicit memory management. vector and map are pretty simple and correspond closely to the python list and dict classes. In fact, I would recommend that new c++ programmers used to scripting languages avoid using "new" entirely. With vectors and maps this shouldn't be too hard.
abstractwater 19y ago
I also had to learn C++ fast, and "Accelerated C++", by Andrew Koenig and Barbara E. Moo was great. The book assumes you are a programmer, it's not dumbed down and most importantly it's only around 300 pages. In the time contraints I had (a month) I couldn't afford to deal with Lippman's C++ Primer or Stroustrup bible (both reknowned books, but over 900 pages). You don't even need to finish Accelerated C++ to start coding in C++. http://www.acceleratedcpp.com/ http://www.acceleratedcpp.com/ For STL, I recommend Josuttis's "The C++ Standard Library". It's a STL reference book, very complete and easy to browse. There are also brief examples on own to use the classes and templates. http://www.josuttis.com/libbook/ http://www.josuttis.com/libbook/
jfarmer 19y ago
Don't read a book, write code. There are lots of open source projects that use C++, maybe try to get involved. Or just give yourself challenges. Rewrite some non-trivial code you did in Python to use C++, for example, and ask experienced C++ people to comment. Also, as others have said, use Boost and STL if you value your sanity. In practical terms, I'd rather use C+Python or C+Ruby than C++. I template in a high-level language and move the stuff in tight loops or otherwise performance-critical sections into C.
brentr 19y ago
I suggest Deitel's C++: How to Program as a good introduction to the language. If you read a chapter a night and do several of the exercises, you could get through the book in under a month. Personally, I think C++ is a great language. Many people don't think as highly as I do of it, instead preferring some of the more dynamic typing languages, but you have a lot of power at your disposal once you manage to wrap your head around it. I got started with C++ because I come from a financial background, and most financial apps in the real world are written using C++. Why do you have to learn the language within a month?

- danohuiginn 19y ago
  It might sound like a cop-out, but the official tutorial. It's short, it's clear, and it covers more ground than it seems to. I'm a big fan of Dive Into Python too, but I'd recommend that for developing good python techniques, rather than getting quickly up to speed.
  - scott_s 19y ago
    Actually, I started out with Dive Into Python, because it was showing me this is how to do it in Python. I can already program in several languages (and paradigms), so I wanted to know what the idiomatic Python way is. By doing that, I absorbed some of the important languages concepts and capabilities. I find that I learn best by example; show me what a correct solution looks like, and I'll figure out why it's correct, and hopefully generalize that to the whole language. Once I started doing some Python programming, I jumped to mostly using the online library and language documentation. Disclaimer: I still haven't used Python extensively, but I feel comfortable when I use it.

thedbradley 19y ago
If you're a fluent Pythonista then I say just dive right in. You could spend a month learning syntax and STL stuff, but a good programmer can pick up a language as they go. See something you don't get? Google-it. You'll be banging out code in no time. Oh, and a Safari account will go a long way to help you quickly find relevant GOOD material (not just script-kiddie posts).

Although it hardly counts as introductory material, I really like a book called Expect C Programming, by Peter van der Linden. The author worked on Sun's C compiler, and has a lot of valuable insights into C. Basically, the book consists of a large list of "these are the things about C which will bite you." For example (please don't just Google for the answer): when is an array in C not equivalent to a pointer? The book contains a chapter on C++; plenty for a C programmer to get started. Unlike sources like the C++ FAQ, I don't believe it makes sense to treat C++ as a language separate from C, and I don't think a C++ programmer without a gut understanding of the semantics of C is a good C++ programmer.
elfred 19y ago

Josuttis' "The C++ Standard Library" is the most heavily thumbed through C++ book at work.

C++ is on my list of 'languages I was forced to learn but would not have chosen to' 1. Languages I chose to learn: BASIC, Assembly Language, C, LISP, Perl, Javascript, Ruby 2. Languages I was forced to learn: C++, Modula-2 3. Languages I have actively avoided: Tcl, Java

kashif 19y ago
Language you should have learnt: Python :) (In good spirit)

allenbrunson 19y ago

i see a lot of people bashing c++ here, and rightly so, i guess. its evolution was too heavily influenced by backward compatibility and pleasing too many masters, in my opinion. i still like to program with it anyway, because i use my own restricted subset. if you're in a hurry, maybe you should learn just plain old C, which is a lot simpler, and then sort of quickly rush through classes and other stuff specific to C++. i'm kind of in the same boat. i'm teaching myself ruby, so i can eventually become an RoR programmer, and join all you hacker news types in the web 2.0 world. before that, i taught myself objective-c, so i could do cocoa programming on the mac. there's some surprising similarities between ruby and obj-c that i wasn't expecting.

C++ feels like a Japanese sportbike for small projects: your code will run crazy fast and it's easy to kill yourself if you're not good enough at it. When your project grows beyond a certain size, C++ starts to feel like early soviet ballistic rockets: plenty fast, but a nightmare to maintain while on the ground, take forever to prepare to launch and can explode at any moment while in flight. I used to love it, up until I bought a Pentium-III 800Mz with 512MB of RAM somewhere around 2001.

Effective STL Programming by Meyers is probably your best bet for comprehension and fluency. Stroustrop is surprisingly good as a walkthrough of the language itself. Modern C++ Design by Alexander Alexendrescu is the best advanced book.

First: Accelerated C++ by Andrew Koenig and Barbara E. Moo -Great book aimed at absolute beginners written by top of the line experts. Koenig worked at AT&T and was a major player in the C++ standards committee. Second: Effective C++ by Scott Meyers -This book is spectacular and will take you from beginner to the next level. It is very well written and an easy read. More Effective C++ and Effective STL are also good. Reference: The C++ Programming Language Bjarne Stroupstrup -This should be your reference book. If you want some Guru level references I can list a couple more advanced books if your interested...

kashif 19y ago
Ok. This sounds like a plan. Thx
- deepsea 19y ago
  Yup. It's a very good plan. The key is Accelerated C++. Just lock yourself in a room with a computer and a coffee machine and get through that book. It's short, well written, and contains examples throughout that you should be typing in as you progress through the book.
anupamkapoor 19y ago
i think "ruminations on c++" by the same authors i.e. andrew koenig and barbara moo is also very good. if you can get your hands on "barton and nackman", its nice too. imho, the fundamental problem with the language is the principal of maximum-surprise. what you don't know can really hurt you...

ilitirit 19y ago

I love C++ There are so many crooks and nannies, pitfalls and gotchas in the language that most people either give up, or they take the time to learn to do things the "right" way. I fall into the latter group. However, I absolutely despise the C/C++ compile/link model. And I hate STL errors, or any sort of error that arise from the incorrect use of templates. And header files need to die. I learnt most of the C++ I know from tutorials on the Web.

If you would like to do something significant within a months' time, learning C++ by reading a book is the worst possible course of action. Start by following along with some basic C++ tutorials. Once you're comfy enough, start implementing your own small applications. (Write a program to accept a sentence from the user and print it out. Then write a function that takes two strings and returns true if the two strings are anagrams. Keep thinking up small apps.) It is my opinion that you must avoid learning STL and Boost if you want to be productive within a month. Both libraries have enough quirks that it takes a significant amount of time and experience to use them correctly. For example, you don't need the std::vector or std::list containers. Simply allocate a sufficiently large array to hold your items, then allocate a larger array when the first one fills up. A std::map container (a dictionary) is also not needed if you're tracking a small number of items. Simply loop through all items until you find the one you're looking for. Basically, start actually writing code as quickly as possible. If you feel like you're burning too much time trying to understand one tutorial, move on to another one. But make sure at the end of each day that you can look back and say, "I wrote a lot of apps today and I feel like I learned a lot." Most importantly, don't be afraid to throw your old code away once you have a better understanding of how best to solve the problem. Implementing components as quickly as possible is the key to productivity. Rewriting your old code is the key to not making a mess. Contact me at palish@gmail.com if you have any questions along the way. I'd be happy to help. I'm a self-taught graphics programmer, so I can relate to how scary C++ can seem at first. Try to implement each application in the simplest possible way.

I have to disagree with your advice to avoid vector and map. If you're used to python, you probably have a very list- and dict-centric method of programming, and you are probably not very familiar with explicit memory management. vector and map are pretty simple and correspond closely to the python list and dict classes. In fact, I would recommend that new c++ programmers used to scripting languages avoid using "new" entirely. With vectors and maps this shouldn't be too hard.

I also had to learn C++ fast, and "Accelerated C++", by Andrew Koenig and Barbara E. Moo was great. The book assumes you are a programmer, it's not dumbed down and most importantly it's only around 300 pages. In the time contraints I had (a month) I couldn't afford to deal with Lippman's C++ Primer or Stroustrup bible (both reknowned books, but over 900 pages). You don't even need to finish Accelerated C++ to start coding in C++. http://www.acceleratedcpp.com/ http://www.acceleratedcpp.com/ For STL, I recommend Josuttis's "The C++ Standard Library". It's a STL reference book, very complete and easy to browse. There are also brief examples on own to use the classes and templates. http://www.josuttis.com/libbook/ http://www.josuttis.com/libbook/

jfarmer 19y ago

Don't read a book, write code. There are lots of open source projects that use C++, maybe try to get involved. Or just give yourself challenges. Rewrite some non-trivial code you did in Python to use C++, for example, and ask experienced C++ people to comment. Also, as others have said, use Boost and STL if you value your sanity. In practical terms, I'd rather use C+Python or C+Ruby than C++. I template in a high-level language and move the stuff in tight loops or otherwise performance-critical sections into C.

brentr 19y ago

I suggest Deitel's C++: How to Program as a good introduction to the language. If you read a chapter a night and do several of the exercises, you could get through the book in under a month. Personally, I think C++ is a great language. Many people don't think as highly as I do of it, instead preferring some of the more dynamic typing languages, but you have a lot of power at your disposal once you manage to wrap your head around it. I got started with C++ because I come from a financial background, and most financial apps in the real world are written using C++. Why do you have to learn the language within a month?

samratjp 19y ago

on the flip side, I have a question for kashif, any recommendations for learning Python really really fast?

kashif 19y ago
Hey Samrat, Here is what I recommend.(order by preference) 1. http://homepage.mac.com/s_lott/books/python.html http://homepage.mac.com/s_lott/books/python.html 2. http://www.diveintopython.org/ http://www.diveintopython.org/
danohuiginn 19y ago
It might sound like a cop-out, but the official tutorial. It's short, it's clear, and it covers more ground than it seems to. I'm a big fan of Dive Into Python too, but I'd recommend that for developing good python techniques, rather than getting quickly up to speed.
- scott_s 19y ago
  Actually, I started out with Dive Into Python, because it was showing me this is how to do it in Python. I can already program in several languages (and paradigms), so I wanted to know what the idiomatic Python way is. By doing that, I absorbed some of the important languages concepts and capabilities. I find that I learn best by example; show me what a correct solution looks like, and I'll figure out why it's correct, and hopefully generalize that to the whole language. Once I started doing some Python programming, I jumped to mostly using the online library and language documentation. Disclaimer: I still haven't used Python extensively, but I feel comfortable when I use it.

C++ FAQ is like an instant cafe for the language, give it a shot! http://www.parashift.com/c++-faq-lite/ http://www.parashift.com/c++-faq-lite/

thedbradley 19y ago

If you're a fluent Pythonista then I say just dive right in. You could spend a month learning syntax and STL stuff, but a good programmer can pick up a language as they go. See something you don't get? Google-it. You'll be banging out code in no time. Oh, and a Safari account will go a long way to help you quickly find relevant GOOD material (not just script-kiddie posts).

Although it hardly counts as introductory material, I really like a book called Expect C Programming, by Peter van der Linden. The author worked on Sun's C compiler, and has a lot of valuable insights into C. Basically, the book consists of a large list of "these are the things about C which will bite you." For example (please don't just Google for the answer): when is an array in C not equivalent to a pointer? The book contains a chapter on C++; plenty for a C programmer to get started. Unlike sources like the C++ FAQ, I don't believe it makes sense to treat C++ as a language separate from C, and I don't think a C++ programmer without a gut understanding of the semantics of C is a good C++ programmer.

I'd also recommend The C++ Standard Library: A Tutorial and Reference http://www.amazon.com/s/ref=nb_ss_gw?url=search-alias%3Daps&field-keywords=standard+template+library&x=0&y=0 http://www.amazon.com/s/ref=nb_ss_gw?url=search-alias%3Daps&... for STL usage.
