<0> test.cpp:33: error: no matching function for call to `test(float[5])'
<1> But really, you don't want to do that.
<1> void test(float* p, size_t elements) { for (int i = 0; i < elements; ++i) { p[i] += 1; } }
<1> Compare to...
<0> ah, you mean i would have to write ugly things like test<5>(p); ?
<1> void test(std::vector<float>& v) { for (std::vector<float>::iterator i = v.begin(); i != v.end(); ++i) {*i += 1; } }
<2> it would copy your whole array every time.
<1> If you're using static arrays, use the first example I typed.
<1> If they're dynamically allocated arrays, use vector instead and the second example.
<0> thx
<0> what i wanted to do works well now :)
<1> Tell your boss to hire me, Victor.
<1> Unless I have to move to Wyoming. In that case, never mind.
<3> void test{transform(v.begin(), v.end(), v.begin(), bind2nd(plus<float>(), 1.0));} might be slightly better
<1> Indeed.
<4> Solamente: you up for telecommuting?
<3> Solamente, unfortunately, the stuff we'd need you for wouldn't work well w/ telecommuting
<2> no *** please
<5> holding hands is not allowed
<2> I didn't know Solamente could gives m***ages.
<1> I'm having a hard time imagining a development project that isn't suitable for telecommuting, anymore.
<1> I only go to the office to allow people to stop by my cube and ask me inane questions.
<2> Can't they use irc for that?
<5> dont need a cube for that
<1> I stay here when I want to get real work done.
<1> Run, these people apparently don't get e-mail, IRC, instant messenger, or telephones.
<5> turn off the mobile and off you go
<1> I don't mind talking to people and answering questions, but it's pretty much all I do when I do have to go to the office.
<2> I'm definitely not happy with how graphviz displays things... it's way more messy than necessary imho,
<3> Solamente, agreed, the problem is that it's not all development... we have some serious design / architecture decisions
<1> vawjr, I do like being in a room for that stuff.
<1> But even now, most of the design meetings I have to do are with customers in remote locations.
<1> So it depends on whom you're collaborating with and the nature of the collaboration, I guess.
<1> And four of the other members of my current team are located in Ohio or elsewhere, so even in-group design discussions are teleconferences.
<3> you have video also?
<5> webcams are cheap
<1> Not for the lowly peons, no.
<6> Run?
<1> I'd like for us to use some collaboration software, but I'm the only one savvy enough to even screw around with it.
<1> That's annoying.
<3> which have you been looking at?
<1> Nothing recently (because nobody else is interested), but even NetMeeting would be better than nothing, and it's no great shakes.
<5> skype
<1> I can't even get them to use a Wiki.
<5> stone age programmers there?
<3> well, I can't even convince them to move away from VSS
<1> Ancient Unix C coders, so yes.
<3> gotta run
<7> Off to office
<1> later
<8> hello
<9> hello
<8> i'm from argentina
<8> and you??
<8> i'm new user c++ :-)
<10> Apple7 : buy a good book, and read it carefully
<8> have questions about c++
<11> I recommend the books at http://rudbek.com/books.html
<8> exception OK
<8> GOOD:-)
<11> ask away
<9> Im from the us
<9> Need somehting?
<8> sorry by my inghish
<12> damn... I have to go to my bank and yell... my debit card isn't working. Too bad I don't have a cellphone, then I could go and wait for the phone call I'm waiting for... shoot
<13> aww crap... just found out my uncle was in a car accident. he's fine and all, but his new Prius is totaled
<11> rdragon was he thinking of getting that 3rd party enhancement to it?
<13> don't know
<8> BeOS is good system
<14> back
<15> how do i fork in dev c++???
<5> using the c++ spoon
<15> huh?
<15> is it possible in windows???
<11> dev c++ is an IDE w/ the g++ compiler
<11> fork is an OS thing
<16> It's CreateProcess (IIRC) and it doesn't work as fork works in unix-like systems.
<17> fork() is POSIX, you won't get that on Windows unless you use cygwin
<5> one doesnt fork in windows
<5> you can use CreateProcess which is about the neaqrest
<15> owww... ok.. thanks a bunch
<17> djgpp included fork() for the purpose of making it easier to port programs (it just always returned failure) so it's possible it might exist in mingw for a similar purpose
<1> mongerz: Are you literally trying to fork a process, or are you just after having another thread of execution?
<15> oh and one more thing. All the samples i've seen demonstrate only a couple of processes concurrently running. i need 3 processes.. just a process Solamente..
<5> you want to hve 3 processes running?
<1> You'll need the Win32 SDK (MinGW provides bare-bones linkage), and the API is CreateProcess, as previously mentioned.
<15> How do i make it that only 3 processes wud run. one for addition, one for multiplication, one for subtraction..?
<5> and how will these processes communicate w/ each other?
<1> Whoa... what?
<9> hy?
<9> why?
<5> i think you need threads
<9> just curious
<1> Indeed.
<15> no need to communicate. i'll just have to show the d processes are running concurrently.
<11> this is a project for school, right?
<1> mongerz: On Unix systems, processes are lightweight so forking a new process isn't a big deal.
<15> it's for our ***ignment. our teacher wants us to use fork.
<9> yea thats what i figure
<1> On Windows systems, however, it's not smart.
<1> Win32 processes are heavy and you *never* want to create one unless it's going to do significant work.
<1> I don't care what you prof wants, either.
<15> yeah.. i'll try it later on linux. am runnin windows ryt now. just checked to see if it's possible..
<17> mongerz, if your teacher wants you to use fork(), the target platform is most likely going to be a Unix, and so developing it on with the Windows SDK doesn't make any sense. You'll need a Unix system to test it on.
<15> it's supposed to be done on linux actually. i was just curious for windows.
<1> If you install Microsoft Services for Unix or cygwin, they provide fork() and a Unix-like environment.
<11> mongerz what cl*** is this for?
<15> ohhh.. i see.. "Intro to OS".
<15> we're using linux actually. was just curious.
<15> anyways, how 'bout 3 processes???
<11> how about them?
<1> fork, fork, fork
<11> if you "must use fork" use *nix
<5> sppon spoon spoon
<1> bork bork bork
<15> shoud i call fork twice??? or a nested if?
<1> www.google.com/search?q=man%20fork
<10> mongerz : be very very carefull with fork in a loop, it's an easy way to use all of the system processes
<15> i will. i don't think i have to use it in a loop though.. i know how to make 2 processes.. the thing is i have to add another which does another job..
<18> alright.... http://pastebin.com/548545
<15> i need 3 processes doing different jobs.
<11> methody it's NOT iostream.h
<18> eek, okay well there's one thing ill change rightaway
<10> mongerz : so have one parent, that forks twice. be sure to check that only the parent forks the second time
<11> methody lines 15 and 17 don't return anything, cant tell about 16
<15> yeah! that's it. how do i fork it twice?
<11> methody your indenttion and grouping {} ****s a casual glance would convince you that line 86 will never execute
<18> vawjrwrk, well it's supposed to just put what it gets from the main into the arrays
<18> oh yeah..
<11> line 28: what is a
<11> have you even tried to compile this yet?
<10> mongerz : you call fork(), check the returned value. if you're child - do first child's job.
<18> vawjrwrk, do you really want to know what a compiler would say to it?
<10> if you're parent - fork() again, and check the value. if you're child - do second child's job, otherwise do the parent's job
<11> no, I'm wondering why YOU don't apparently know what a compiler will say about it
<19> does anyone know how can i put a timer in c++?
<14> bye all
<15> ok am gonna try it. i'l reboot to linux. thanks a lot.
<18> well here are the first couple of errors... (there's only eight but there'd probably be more if i made those work)
<18> U:\cplusplus\cprogram\adsfa.cpp(16) : error C2059: syntax error : '&'
<18> U:\cplusplus\cprogram\adsfa.cpp(17) : error C2059: syntax error : '&'
<18> U:\cplusplus\cprogram\adsfa.cpp(17) : error C2535: 'int __thiscall database::time(void)' : member function already defined or declared
<18> U:\cplusplus\cprogram\adsfa.cpp(16) : see declaration of 'time'
<11> methody it's YOUR program, fix it
<19> heeeeeeeeellllllllllo
<18> do you think i'd p*** like that vawjrkwrk :P
<18> it'd*
<20> post the program on pastebin. Errors arent any good to us
<11> methody hell no, it won't compile
<18> it has to get some mark.. i mean it's go SOME similarities to a c program right..?
