----------------------------------- apomb Fri Sep 24, 2004 2:16 pm Where do i start? ----------------------------------- I am starting C++, what would be the best place to start (code wise). Some of you might remember me from the Turing section, so i have some background in that and some java, although not extensive, i do know syntax and whatnot, and i hear C++ and java are similar in those respects. Anyway, is it better to start with pure syntax or just try to create from what i already know? please suggest - Compwiz ----------------------------------- Andy Fri Sep 24, 2004 2:30 pm ----------------------------------- for noobies, i suggest VC6... it does lack stability and consistancy, but it'll work... start by remaking the old progs u did in other languages in c++, just dont do any graphics cuz then u'd have to use MFC/Direct X/OGL and all three are quite painful for starters ----------------------------------- wtd Fri Sep 24, 2004 3:01 pm ----------------------------------- Absolutely not! Visual C++ 6 is one of the worst C++ compilers available in terms of standards compliance. There's nothing worse for a student than being shown valid code and getting errors when compiling it. GCC is available free and does a far better job than VC++6. As for "Where to start?"... I would start with basic concepts and then apply syntax to them. Do you understand: ... the purpose of main? ... how to use includes and what they do? ... how to declare variables and assign values to them? ... how to create functions and procedures? ... the difference between a function and a procedure? ... how to specify that a function or procedure has a parameter? ... how to specify that a parameter is a reference? ... why you would pass an argument into a function or procedure as a reference? ... how to pass an argument or arguments to a function or procedure? ... why you should use functions and procedures liberally? ... why this is better than using global variables? ... how to create forward declarations of functions and procedures? ... why and when you should do this? ... integer arithmetic: why 3 / 2 = 1? ... how to read data in from standard input? ... how to write data to standard output? ... what a pointer is? ... how to create a new pointer variable? ... how to get a pointer to an existing variable? ... that a pointer is just a variable storing the location in memory of another variable? ... that pointers allow for dynamically allocated, rather than statically allocated memory? ... why this is important? ... how to allocate memory for a pointer? ... how to free that memory later on? ... how to declare an array? ... that an array stores several values of the same type? ... that the name of an array is just a pointer referring to the first value in the array? ... that, as a result, arrays can either be statically or dynamically sized? ... that it's possible to create custom data structures which combine multiple pieces of data into a single "thing"? ... how to declare a struct? ... that doing so adds a type to the system? ... how to create a variable of that type? ... how to access the individual components of a struct? ... that it's possible to put more than just data in a struct? ... that such data structures are called classes? ... that access to the things in a struct or class can be modified? ... that the only difference between structs and classes (in C++) is that everything in a struct is public by default, while everything in a class is private by default? More to follow. ----------------------------------- Mazer Fri Sep 24, 2004 8:43 pm ----------------------------------- For just starting, you'd probably want an IDE to work with. Dev-C++ is pretty nice, and it saves you the trouble of buying/pirating MSVC++. And I believe it is possible to have it compile your programs with gcc (somebody please correct me if I'm wrong). ----------------------------------- omni Fri Sep 24, 2004 8:45 pm ----------------------------------- wow i understand 70-80% of that list. I feel like I'm making progress. :) ----------------------------------- rizzix Fri Sep 24, 2004 8:53 pm ----------------------------------- aha i just tried this out just 2 days ago and now its the only one i use (if i use an ide i.e): CBuilderX by Borland.. it comes with two choices for a compiler: borland's own and GNU's imho Dev-C++ is a buggy ide.. not stable at all.. i know its a work in progress and it has some cool features and stuff but its just not good enough for me. so i've decided to stick to CBuilderX. its pretty good.. and very much similar to their JBuilder IDE. but if ur really into c++ development and you know how to write your own makefiles.. then u should try out Eclipse with the CDT plugin ----------------------------------- wtd Fri Sep 24, 2004 9:06 pm ----------------------------------- Those new to programming would be best advised to avoid IDEs entirely for awhile. They tend to make things seem more complicated than they are, they make it difficult later on to distinguish features of the IDEand the language, and the command-line skills are good to have. ----------------------------------- wtd Fri Sep 24, 2004 9:51 pm ----------------------------------- wow i understand 70-80% of that list. I feel like I'm making progress. :) I wasn't even remotely done. ;) ----------------------------------- Mazer Sat Sep 25, 2004 1:53 pm ----------------------------------- but if ur really into c++ development and you know how to write your own makefiles.. then u should try out Eclipse with the CDT plugin Which reminds me... would anybody care to write up a tutorial on creating your own make files? I'll be needing that information in the near future and even now it'd be good to know. compwiz333: sorry if I'm hijacking your thread with this ----------------------------------- apomb Sat Sep 25, 2004 3:00 pm ----------------------------------- WOW... i almost dont have enough time right now to read all of this, but THANKS guys! i understand about 40% of what i read,which wasnt much right now, but i will definately look at all of that when i have time, anyway i cant believe all this help! Thank you, i will get started right away! :D i think i will take the advice of dodge and remake some of my turing text- based proggies. wtd: that was alot of info ... one big question that i have had since i heard of them are pointers ... what the **** are those!? Oh ya and at my school, i think they have VC++6 too :? is this that terrible, im kinida getting mixed messages.... so borland at home tho ... right? :eyes: *going crazy from all the information* :eyes: ----------------------------------- Andy Sun Sep 26, 2004 6:18 pm ----------------------------------- w00t after u get the hang of it, learn getpixel :D ----------------------------------- wtd Sun Sep 26, 2004 9:57 pm ----------------------------------- wtd: that was alot of info ... You're welcome. :) one big question that i have had since i heard of them are pointers ... what the **** are those!? A pointer is a variable which stores the address of another variable, rather than the actual value of that variable. Oh ya and at my school, i think they have VC++6 too :? is this that terrible, im kinida getting mixed messages.... so borland at home tho ... right? :eyes: *going crazy from all the information* :eyes: Yes, Visual C++ 6.0 is absolutely horrible. Borland is decent, from what I hear, but it's a fairly niche compiler. GCC (the GNU Compiler Collection, which includes g++, their C++ compiler) is your best bet. It's widely available on Unix, Linux, Windows, Mac, etc. ----------------------------------- apomb Sun Sep 26, 2004 11:25 pm ----------------------------------- A pointer is a variable which stores the address of another variable, rather than the actual value of that variable. oooh!!! thats kinda kool. i can get used to that! started downloading the borland one ... first one i found! (finished tomorrow!) stupid 56k ... dont laugh, i offered to pay for highspeed but my parents are against the furthering of my knowledge haha ----------------------------------- wtd Mon Sep 27, 2004 3:17 am ----------------------------------- A pointer is a variable which stores the address of another variable, rather than the actual value of that variable. oooh!!! thats kinda kool. i can get used to that! Yes. It makes certain interesting things possible. However, don't get too used to them. Pointers are powerful, but they're dangerous too. Understanding them is key to understanding C++, but that understanding includes knowing when not to use them. A simple example: int i = 42; Pretty standard stuff, right? int i = 42; int * j; Whoa! Hold the horses! What's that * doing in the middle of things? That's the C++ (and C/Obj-C) way of declaring a pointer variable. But right now it's npt pointing to anything in particular, which in C and C++ terms means it could be pointing to any random thing. Can't overstate how dangerous this is. int i = 42; int * j = &i; Much better. We've initialized the pointer with the address of i. The & is the "address of" operator. Read that line as "integer pointer j is address of i." int i = 42; int * j = &i; std::cout
