<0> so like.. void funct(const int size) { char test[size]; }
<1> Metall|ca, hmmmm, and that doesnt work ?
<0> nah, it says storage size of the char isnt constant.
<1> also const int &size is probably a better approach
<0> so.. in this case "test"
<0> ill try
<1> oh
<1> although to reduce the change of a segfault you probably want to test size within the function first
<1> change = chance
<1> e.g. if(size <= 0) return; or something :)
<1> Metall|ca, where abouts in NSW are you from?
<0> hunter valley
<1> choice
<1> near that power plant?
<0> I cant even do the following. const int Size = 256; char test[Size];
<1> hmmmm
<0> Umm, im not too sure.. is that on the freeway to sydney?
<1> Metall|ca, yes
<0> im near maitland
<1> nice
<0> yeah, moved here from new zealand 6 months ago
<0> oh wait, i can do the following*
<0> just not when i p*** the variable through a function call
<2> Bah
<2> 4am it too early to wake up
<1> Ashe`, It is 12:06 PM though :)
<0> I even set a global int for it, and it says that the storage size isnt consistant :S
<0> Im using static chars, thats why this is happening. but i need to use em
<3> hi!! does anyone here could help me.
<3> i compiled my program in winxp using Visual Studio 2005, but when i tried to run the exe in another system also winxp
<0> You need to have some of the vs2005 files on the other pc also.
<0> thats why i stopped using vs2005, and turned to devc++ :)
<4> you need to deploy the runtime
<4> Metall|ca that doesn't eliminate the 'problem'
<4> it's just that VS2k5 is new, and so not many people have the runtime installed
<4> ebros - create an installer project for your application
<4> you can use that to bundle the runtime into the installer, and it'll take care of installing it
<4> also make sure you've built in release mode
<3> how can i deploy the runtime? is it included in the framework?
<4> if you have the express version of vs2k5, there are different steps
<4> ebros the easiest / best way to do it is by creating an installer for your application (it's really, really simple)
<4> if you create a new project, under 'other project types' you'll see 'setup project'
<3> ok ill try to create an installer. thanks very much rdragon :)
<0> MSV2005 Express doesnt have that option rdragon.
<3> btw im using the professional edition. does it have the installer feature?
<0> It should do if rdragon says so.
<4> yes, ebros
<4> to your solution, "Add New Project" > "Other Project Types" > "Setup and Deployment" > "Setup Project"
<3> ok done. whats next rdragon? :)
<4> find some documentation about creating setup projects
<4> although if you play with the ide, you could figure it out
<3> alright ill just experiment : ) thanks again
<0> Funct(const int Size) { static char ch[Size]; } <<when i try this. it says i cant Size, unknown value. and compiles with an error.
<4> Metall|ca you can't do that
<4> array sizes need to be known at compile time
<4> if you need a dynamically sized array, use std::vector
<5> in fact whether you need one or don't , just use std::vector
<0> I can do this tho static char *ch = new char[Size];
<0> but creating it dynamically doesnt seem to work well with my function.
<5> if you're mucking about with strings, use std::string
<4> Metall|ca - that's not an array, that's calling new at runtime, and p***ing it a parameter (Size)
<4> and it returns a chunk of memory that can be used for Size char's
<4> but yeah, use std::string
<5> also, buy a book if you want to learn C++
<0> I really dont need to use std::string, Ive made my own function calls to do pretty much the same thing.
<5> using char arrays?
<0> using chars, yes.
<4> then get rid of them, and use std::string
<4> i doubt you've written a better string implementation than the library writers
<0> i probably havent, but it works fine for me.
<5> there will come a point when it will not
<5> then you will waste time fixing it, instead of focusing on solving the actual problem at hand
<5> C++ is annoying enough as it is, no need to make it more so for yourself
<6> or quit compiling things for dlls in vs2k5 and use static linking instead
<6> yeah, writing your own string is foollish. Others won't be able to read your code and it's unlikely it will actually work with all the things in <algorithm>
<0> vawjr, i dont use vs25k.
<0> And also, others dont read my code, as i program for myself :)
<7> that's not due out for a couple years anyway
<7> (vs25k)
<5> Metall|ca: please take our advice
<5> we only suggest it because we care
<4> and because it's easier to help when everything is a tangled mess of your own doing
<4> isn't
<0> lol
<0> alright, ill redo everything again using std::string.
<4> get a book, too
<5> ya that too
<0> What for?
<5> calc koenig2
<4> to learn
<5> boo
<0> learn what? how to use std::string?
<4> how to write proper C++
<5> http://rudbek.com/books.html <---the first book on there
<6> Metall|ca the vs25k comment was for ebros
<6> Metall|ca how to write C++
<0> I can write c++ fine :) maybe not at an IT level.
<6> if you wrote your own string you can't write C++ fine
<0> I never wrote my own string, i made a few functions like std::string has.
<6> so you use the strxxx stuff and your own "few functions" ?
<1> does cin.read(char*, size); null terminate the string?
<7> yesw
<7> wai
<7> er
<7> I'm thinking of getline()
<7> hm
<1> hmmm
<7> I would have to guess no
<1> ok
<7> I would also guess that it won't stop if you hit enter
<7> it will keep reading until it reads how much your asked for or your send EOFE
<7> EOF, even
<1> your right it doesnt NULL terminate
<1> oops I ment ifs.read(); :) not cin ( where ifs = ifstream ifs)
<5> same thign applies
<1> same thing though
<1> yep
<1> I thought so
<6> threat why wold you care? use std::string .... forget all that char* crap
<6> but to answer your question, it does NOT put a '\0' at the end
<8> Hi im having problems compiling a program from scheme to C
<8> can some one help me?
<6> this is a C++ channel, not C, if you really mean C: /join #C main
<8> ok
<9> hy guys
<9> any idea how to dump the ram to a file ?
<7> you can get a core dump
<10> Join #0p free op (@)
<7> (if that helps)
<9> how ?
<7> I'm not sure the most proper way
<7> if you have your OS configured to create them by default, then yo ucould do it by raise(SIGSEGV);
<7> though that is sort of a hack
<9> what library ?
<9> raise is c99 ?
<7> POSIX
<7> #include <signal.h>
<9> just raise ?
<7> well that will generate a Segmentation fault
<7> depending on your system configuration it may or may not generate a core dump
<9> but using pointers do I have a chance ?
<7> eh?
<7> what system are you on, anyway?
<9> xp, fedora4
<7> fedora should be able to give you a core dump
<7> I don't know about windows
<7> you just want to browse your own processes' memory?
<9> not just browse but write
<7> erm, why not just use a normal pointer to the data then?
<9> void *p =0x0000h;
<9> and cout p
