<0> but the error about 'ostream': 'friend' not permitted on data declarations is still there
<1> how many errors do you have?
<1> and what is the first one
<1> infact, give us the entire list
<0> i have 70 something errors
<1> o...k
<1> and how far down the list is this one?
<0> #2
<2> Paragon`: You should show all of the source code, and then we'll know immediately what is wrong.
<2> A single line is not enough.
<0> ok
<2> And you normally only need to give the FIRST error, the rest is nonsense is 99% of the cases.
<1> aye, often fixing the first one kills off most of the rest
<0> ok
<0> well im gunna paste the whole thing now so sec
<0> this is the implementation of the cl***
<0> http://www.noidea128.org/sourcefiles/16023.html
<0> http://www.noidea128.org/sourcefiles/16024.html
<0> that is the declaration
<2> I think it never heard of ostream
<0> hrm
<0> heh
<0> #include <ostream> could be a problem huh
<0> forgot that
<2> You should never put 'using namespace std' in a header, so write std::ostream
<2> and include <iostream> yes
<0> yah
<2> though you might get away with <fwdios> or what was the name
<2> #include <iosfwd>
<1> i usually use the "using std::ostream;" method as opposed to specifying the namespace everytime
<1> or whatever
<0> ok
<0> that brought me to 36 errors
<0> namespace and iostream
<1> post the errors
<0> duh sorry for that stupidity
<2> nnp: You can't put that in a header file, not at the 'root'. Maybe in the cl*** itself.
<3> I don't think iosfwd declares all the operator << instances.
<2> _m_ : just for std::ostream
<2> std::ostream& even
<0> well im going to work on them myself for a while
<0> thats for the nub slapping
<0> actually
<0> illegal escape sequence
<2> I almost always write the std:: everywhere... it makes code more surveyable
<0> on the public member overload of /
<0> ?
<2> you wrote operator \ dude
<4> paragon: I'm here to help you
<2> not /
<3> Run: many operator<< instances are declared as free functions in <ostream>
<2> _m_: so? :)
<3> so you need <ostream> for <<
<0> heh sorry
<0> im tired and rushed
<0> i have like 15 min to finish this :(
<2> He only needs std::ostream to be forward declared to make some function a friend that uses std::ostream& as return type and parameter.
<2> That that function is operator<< makes no difference.
<3> For the header files, right. I was looking at http://www.noidea128.org/sourcefiles/16024.htm
<3> l
<2> ok
<5> Hello.
<2> eeck... .com.br
<2> Must be a spammer :)
<4> lol
<2> Or did that change these days? I firewalled .com.br 5 years ago and never removed it again :)
<4> <4> lo.
<4> <5> heya
<4> <4> are you a spammer?
<4> <5> no
<4> he says he's not a spammer
<5> I am not a spammer. There's some time i use to join this channel
<2> Well, this is irc - I was refering to email
<5> Man, i'm really from brazil :)
<2> I was just kidding (not about /dev/null-ing all mail that I receive from .com.br though)
<5> np
<0> can friends access private data members?
<2> yes
<0> hrm
<0> its telling me it cant
<0> in my >> overload
<0> i'll paste
<2> Paragon`: You'll get ambiguity by declaring both,
<2> friend rational_number operator+(const rational_number &, const rational_number &);
<2> and
<2> rational_number operator+(const rational_number &); inside the cl***.
<2> I'd go with just the first.
<0> http://www.noidea128.org/sourcefiles/16025.html
<0> well the ***ignment is to do both
<0> then in a client
<0> show how each works
<2> Paragon`: missing ;
<0> crap
<0> oh
<0> doh
<3> istream &operator << <--- what is wrong
<0> heh
<2> _m_ nothing
<0> oops
<2> oops
<2> should be ostream :)
<2> And I'd write: std::istream& operator>>
<2> I was just looking at the space abuse.
<2> Paragon`: You should put the '&' against the type (see http://www.xs4all.nl/~carlo17/c++/const.qualifier.html for a rationale).
<2> That URL is mostly about writing TYPE const& instead of const TYPE& (which isn't done by all C++ guru's) though.
<2> All C++ guru's write TYPE& foo; and not TYPE &foo;
<2> or, TYPE & foo; as you seem to do.
<0> thanks will have to get to that after cl***
<0> gtg
<0> thanks for help :)
<5> I tried to store the number "123456780001" into all kind of int's (short int,long int,blabla). Not worked. Is there any other type of variable (with exception of std::string) that i can store this number?
<6> unsigned long perhaps?
<6> depends on the platform too...
<5> Windows XP. I stored in std::string , but i want to store in a kind of int
<6> did you try unsigned long?
<5> i will try again
<5> but not worked.
<5> it stores a different number
<6> long long is available in vc++ (part of C99)
<7> "123456780001" as written is not an int..its a string
<5> hmm,it explains why i stored it in a std::string
<6> huh? you actually tried to store it like, unsigned long i = "123456780001"; ?
<5> lemme check. I'm using Dev C++
<3> 123456780001 is of type int, no matter what type you try to store it in.
<3> Try 123456780001L for long and 123456780001LL for long long literals.
<5> YUY0x7: unsigned long int not worked
<7> without the quotes obviously
<5> worked with long long int
<5> thats strange
<6> P-Brasil, i was asking if you were doing that (which is obviously incorrect)
<5> i tried long long before and dev c++ not allowed me
<5> strange
<5> YUY0x7: Okay,sorry.
<3> P-Brasil: no, it's not strange.
<3> 123456780001 is of type int.
<3> if it doesn't fit into an int then it doesn't, no matter of what type the variable is you're trying to ***ign that number to.
<3> Use 123456780001UL for an unsigned long literal.
<5> <3>: I got it working with a long long int
<8> opme
<8> sigh
<9> got a question guys, i'm tryint to get somethign that searches a weblog for hits. it addes them to an avl tree and if find a dup just increments a counter so no dups have their own nodes. now i think it's doing everything correctly however the text screen will only hold so much data. i mad a no recursive (using a stack) method to transvers tree in order and outfile<< p->info << p->count; now for some reason it will run, but nothing gets
<8> avl tree? you did your own??
<9> yes
<8> the standard library has such things (well red-black not avl, but....<shrug>)
<10> min is a simple avl one, with a modified node to just hold a counter
<8> and it has traversal alredy written
<8> and tested
<10> yes
<8> avl is NOT simple
<8> and I'm not really up to help debugging one when red-black is almost as good for most things and it's _standard_
<10> the recurisve works, and so does the non. i added the none thinking maybe it didn't want to output to file because of some recursion error like filie open or sumthing
