<0> it's been downhill ever since.
<1> cl*** MyVector : public vector {
<1> };
<1> and you show it to your teacher
<2> lol
<3> Visual Basic is confusion distilled into a programming language.
<4> Noid858 how are you supposed to implement this dynmic array? as a cl***? or as free functions?
<2> rdragon: He didn't specify but I am doing it in a function format cause I feel its easier
<5> hmm
<4> it would be much more trivial to do it as a cl***, and just mimic what std::vector does
<5> aliright c++ it is i'll get started on it tomorrow
<2> rdragon: I'm not allowed to call any of the methods from the vector cl***
<4> Noid858 that's not what I said
<4> cl*** Noid858sVector{ ... };
<6> shoot... ran a program and used all my memory... m***ive page swaps... so slow!!!
<4> build all of the functions for adding and removing elements from your vector cl***, and have them manage the internal raw array
<3> jsaacmk: That's what you get for using genetic algorithms to balance your checkbook.
<4> you can even provide iterators so your vector is compatible with standard algorithms and such
<6> bah, it's only a 4096 * 32 size DFT that creates a (4096 * 32)^2 sized table...
<2> rdragon: Trust me I would if he would allow it but he will not. :(
<6> 17179869184 bytes
<4> i thought you said he didn't specify?
<4> isn't the whole point to essentially implement a dynamic array?
<6> 16 TB
<6> it might crash... sometime
<4> template<typename T> struct Vector{ T* data; std::size_type size; std::size_type capacity; ... };
<4> s/struct/cl***
<2> Yes the point is to implement a dynamic array from scratch.. Insert a value into the front, middle and back of the array and be able to remove from the front, middle, back.
<4> okay, so what's the problem in implementing it as a cl*** ?
<2> Because he wrote this long *** program that we are eventually going to write ourselves. From his example program he creates a cl*** but does not mimic any vector. He uses ***erts to see if the system has enough space on the heap to create a new dynamic array. He uses memcpy to copy arrays..
<5> guys anyone know any good visual studio 2005 or visual c++ tutorials?
<5> that are VIDEOS< not text
<4> well, then he's doing things wrong
<4> new throws std::bad_alloc if it couldn't allocate
<4> but that exception should really be p***ed up to the application, I think
<2> I have a **** for a professor and I gotta put up with his crap. If I want a good grade I have to do it his way. So unfortunately this ***ignment is due tomorrow. I've been working on it for 8 hours and I feel like giving up. I can't get my stupid *** program to delete a dynamic array without creating a heap exception
<4> maybe you're deleting something that's already been deleted
<2> http://www.noidea128.org/sourcefiles/15910.html
<4> if it was all contained in a cl***, the whole implementation would be trivial
<2> ^^^ do you see anything wrong with my code which wouldn't allow line 77?
<4> at least put the pointer to the array, and the size in a struct
<4> that would be the C way to do it
<2> Ok I'm going to re-program this thing into a cl***
<4> good guy... you'll relieve all of your headaches
<2> rdragon: doubt it
<4> you need to store at least 3 main pieces of data: the pointer, the size, and the capacity. the size should be initialized to 0 and should change when elements are added/removed from the container.
<4> the capacity is how many elements the memory that the pointer points to can hold before you need to reallocate it bigger - a decent strategy is to double the capacity each reallocation
<2> Working on it
<7> hi... I'm using this program that has a DLL written in C++ 6.0 and it has the source. I have to modify this dll for a project. I'm using VS .NET 2003. When I try to compile the project (so the program generates the updated DLL file) it just generates a bunch of files and says OK, but no DLL is created. Can you please help?
<8> neat, it works (vista)

<8> "bunch of files" like what? are there any errors?
<7> no errors, the following files are generated:
<8> VS 2005 is available, by the way
<7> <name>.obj, <name>.pch, etc
<7> but no <name>.dll
<8> did you convert this dll project from vc6 ? verify that the project settings are set to generate a dll?
<8> rebuild all?
<8> paste the whole build log to the paste site
<8> what does the end of the build log say? (X errors, X warnings)
<7> hmm let's see, apparently it is generating the DLL in another directory, even when on Project Properties it says otherwise... let me see if that is the updated version
<8> project properties > output directory
<8> and/or librarian > output file
<9> hi
<9> what could this mean: http://rafb.net/paste/results/MIeTpG64.html ?
<9> I am trying to use valarray
<8> how about some code?
<10> corstan it looks like somehow you've messed up calling a constructor
<10> and no, I don't know how to do that
<9> it's OK now
<9> did this: Vector xold(m.getRows), xnew(m.getRows), b(m.getRows);
<9> where Vector is a typedef
<9> I should have done: Vector xold(m.getRows()), xnew(m.getRows()), b(m.getRows());
<4> what's Vector ?
<9> rdragon, typedef valarray<double> Vector;
<4> really need a typedef for that?
<9> yes :)
<4> and you really want to call it vector?
<9> that's what it is meant for
<9> solution vector from a matrix-vector product
<4> isnt a vector just usually an x,y,z tuple?
<10> depends on the dimension
<9> an array of length n could be thought of as a vector
<9> in linear algebra
<10> or in any geometry of dimension n
<10> it can also be thought of as a point in said geometry
<9> yews
<10> since there seems to be a big difference between row vectors and column vectors, I would have thought you'd keep the separate
<9> dealing with sparse matrices here from PDE solution techniques
<9> so I am
<9> jcol
<9> and irow
<9> that are double arrays
<10> I meant as different cl***es
<10> I don't give a **** how you represent them
<9> ??
<9> what's the point in making cl***es for solution vectors
<10> I said for row vectors and column vectors
<9> just make a cl*** MyArray and implement it as a 2D array problem
<10> or 1 x n and m x 1 matrixes your call
<9> can someone kill that bastard ypeter92hzl
<9> "***e #horny Free Chat" ???
<9> vawjr, do you see any possible failures with this statement:
<9> int length = sizeof(array)/sizeof(double);
<9> cout << length << endl;
<9> I get 0
<9> even though array is of length 1000
<9> hm, maybe I should dereference it
<9> no
<9> anyone else?
<4> maybe you should learn about how division works
<4> (since it looks like integer division)
<4> what does sizeof(array) return, and what does sizeof(double) return?
<4> and what is 'array'?
<9> pointer to an array
<9> size of the pointer, hmm
<4> why are you using a raw array?
<9> wrapping up for C code
<9> pretty inefficient
<9> but I don't care atm.
<4> unless it IS C code, there's likely no reason to use a raw array, if it's supposed to be of varying size
<9> I am communicating with C functions that do not understand STL containers
<9> such valarray or vector
<9> ...as...
<4> that's not a deal breaker
<4> vector's guarantee the contents are in contiguous memory, and you can get a raw pointer to the vector's data
<9> I did know that
<4> std::vector<int> vec; ... int* i = &vec[0];
<9> so if I have double* array
<9> as an argument to a C functiobn
<9> function
<9> I can use valarray<double> vec(length); ?
<9> without making an explicit double array and then p*** the contents over ?
<9> ok
<11> ANybody in #c ?
<9> yes
<9> /j #c main
<11> Thank you
<9> rdragon, what if that vector should be const
<12> hey vawjr, why are you such a ****er of cocks? do you like the taste of the skinflute? you homo faggot..
<9> in the C++ function
<9> who the heck was that
<9> or what
<9> but just a raw double array in the C function ?
<9> can I work some way around that
<9> rdragon, should an inline function be like this:
<9> void inline MatSparse::Jacobi1it(Vector& xnew, const Vector& xold, const Vector& b) {} or
<4> get a damn book already
<9> inline void MatSparse::Jacobi1it(Vector& xnew, const Vector& xold, const Vector& b) {}
