paddy4destiny: i hate pointers in pascal. I dont even understand the concept. It sucks. I think is same with c++ That's all we need Next |

paddy4destiny: computer engineer whats the concept. Pls throw more lightC++ pointers are easy and fun to learn. Some C++ tasks are performed more easily with pointers, and other C++ tasks, such as dynamic memory allocation, cannot be performed without them. As you know every variable is a memory location and every memory location has its address defined which can be accessed using ampersand (&  operatorwhich denotes an address in memory. Consider the following which will print the address of the variables defined: #include <iostream> using namespace std; int main () { int var1; char var2[10]; cout << "Address of var1 variable: "; cout << &var1 << endl; cout << "Address of var2 variable: "; cout << &var2 << endl; return 0; } When the above code is compiled and executed, it produces result something as follows: Address of var1 variable: 0xbfebd5c0 Address of var2 variable: 0xbfebd5b6 think am liking cplusplus. With my little knowlegde of pascal i think i will grasp it in no time. Never liked java for one day 1 Like |

paddy4destiny: C++ pointers are easy and fun toone love sir...! . . . me still dey talk sey, i would rather learn Arabic writing than a programming language called Java  C++ pointers gives you so much power and flexibility at a certain cost... And its exceptional! Also gives the comfort ride of C... Actually, pointers are pretty simple, thanks to the compiler for precomputing the memory sizes of datatypes and objects for pointer arithmetic. . . . I wrote a little bit advanced tutorial on that a month ago.... paddy4destiny:oboi, because I talk say I dey robotics engineering discipline no mean say I don collect my degree for robotics engineering oh... make I finish and join IEEE-RAS first... Anyway, I was laughing at spike C's reaction not your post.... |

WhiZTiM: Fucck you! Don't learn!, who needs you?? We don't need a naive mind like you!. They are already too many hacks in this field, you would just add to the lot. So fucck off! Kip showing how ignorant you are!  IMHO, there is no Super Programming Language, Only Super Programmers. No doubt, C++ is a great Language, but for me, its JAVA all the way, slow or not!!  @Whiztim, Quickly, go and learn your 'Arabic' writing, iHope it makes you live long #TeamJava 1 Like |

@judinho, you are making point. A good programmer will create faster codes. And besides to a regular user, he might not even notice the speed difference. If you want speed go for assembly. I hated c++ from the time i saw it, but that won't stop me from using it when needed. The time you guys are putting in dragging you would have used it to build opensource projects or help the languages you drag for. I still hold my stand, c++ and java are great languages and i will use them when neccessary but java rocks for me. #teamjava 1 Like |

Haba!! Ask For Clarification! Challenge Me! And Query Me where appropriate... some of you really lack BASIC psychology skills. . . . Did I ever tell anybody I make my living solely off programming? . . . Did I ever say I would be into programming all my life? . . . What do you know about me outside Nairaland? So, attacking me for my subjective statement is outrightly pointless and TOTAL STUPIDITY... Just as started by a 'block headed', 'crackbrained', and 'shallow minded fellow'... I don't even know the gender of that person... Still, I rather learn Arabic writing than a programming language called Java. C'mon guys, where's the Nigerian spirit! |

 ^^^ Nigerian Spirit eh??  Verdict: Java 'out-mouthed' C++ on this one Thread Closed!! |

l.m.a.o Java sucks!, Java is a useless language!, i would rather learn Swahili than learn Java #hahaha @whiztim C++ rules, C++ is the greatest language in the planet, C++ is used for building artillery softwares I don gree!...  Whether you would ever learn Java or not is no ones business shaa, like someone said it doesn't remove the v from Java. I myself i don't see myself using a language like C# or PHP. Not because i have anything against them but i don't see any need to. I am a Game Programmer, Currently using Java/Flex/Flash for mobile and browser games. In a few weeks time i would start doing H.D. /3D games, and i intend doing it fully with C++. Like i said earlier i spent sometime the last few weeks learning C++ and since then every time i visit TopCoder i attempt the problems in C++, just to master the syntax. Sorry for the insults man, you are a smart programmer, One of the smartest on this board and i admire your post alot . But please drop whatever beef you have with Java because it won't change the fact that Java is a great language and would always rival C++  What you are doing is like hating on a player like Lionel Messi, He would keep scoring goals and giving you heart attack, Like i earlier said, Java isn't the most popular language in the world for nothing, you are not smarter than all those programmers using it..._Anyway, my job here is done.... _One_Love_Bro... _Signing Out #continues debugging code |

pc guru: same here, Infact am currently porting a java app i wrote 2 yrs back for the red5 streaming server back to python. I realized this as there seem to be a huge difference running a streaming server in python than in java. at java startup, the memory drink is usually about 400MB on linux, just the JVM, no app yet. where as python starts up at 2.5MB |

apparently java users have failed to figure out that creating class instances in java is actually done by pointers. the only difference is that the asterisk (*) sign is omitted. what do you think happens when you use the "new" keyword? all user created objects cannot be created on the stack but on the heap which means that whether you want it or not memory is dynamically allocated for you and then deleted whether the developer likes it or not and when it is necessary or unnecessary. . not cool. . pointers is one of the most beautiful concept in the programming paradigm. it is being used by most languages in one form or the other. its just that the implementations are hidden from the developer. in some languages, all the objects are pointers. like in python, all variable instances are pointers. if you are in doubt check the python interpreter documentation.. . hating on pointers is probably hating on your own programming language. Nevertheless, if you have said any foul thing against pointers on this thread you should get on your knees wherever you are and pray solemnly to the God of pointers to forgive you for your blasphemy against it. |

But regardless of how i feel towards Java, i will use it cuz preference is not an option for me, i use whatever tools is useful. But C++ is my ultimate life mission to master. Reading emulation made me realize how important and powerful c++ is , i was always eager to understand how emulation of playstation works. |

webdezzi:You work with red5 nice always wanted to use that but mehn it required strong Java. Nice one |

WhiZTiM: Haba!!lwkmdead, you just prove my thought. @all, but come to think of it, if all the so called godfather didn't see great potential in java, will they support it ?. Thats simple and straight forward. |

"If you learn to program in Java, you’ll never be without a job!" BTW, "The more i C, the less i see". #QuotesFromGreatMinds Y'all have made your point, the Battle of programming languages' meaningless. |

Judinho59: "If you learn to program in Java, you’ll never beYep its actually meaningless debating , the fact i dislike it doesn't mean i won't learn to use it even currently my school project is in Java (Processing). and Yes Java too does have Jobs also |

I have stated your same point in the past here and i can recollect many geeks here demanding for my head be it java, python, C, php they all speak to the same underlying operating system and that answers why endians(when working with bytearrays), file path separators(unix/windows file system), filename case sensitivity etc behaves same way across languages relative to OS |

Today i was thrown apart by a Project online, i work with Java Processing and Arduino Board, someone made a nodejs package that interacts with the Arduino using JavaScript via C++. He created a C++ Extension then use Nodejs to communicate with it via JavaScript, what this means is that soon you can use JavaScript to gain access to Hardwares via the browser with C++. very impressive stuff |
