    why does initialise with vector not work here ?

    This class:

    #pragma once
    #include <vector>
    #include "um.h"

    #define MAXMROOT 9 /* 2^(MAXMROOT-1) = # of elements in BRcnt */

    class FastFourierTran s
    {
    public:
    FastFourierTran s(void);
    ~FastFourierTra ns(void);

    public:

    void FFT2D(vector<ve ctor<CComplex InputArray,
    vector<vector<C Complex OutputArray, long N,long sd);


    };

    throws the following error i do not understand:

    1>e:\daten\dev\ cpp\lightmodula tor2dmat\lightm odulator2d\Fast FourierTrans.h( 34)
    : error C2061: Syntaxfehler: Bezeichner 'vector'

    Parameterliste im alten Stil?

    What is wrong ?

      It seems that the error message from compiler is not in English. SO,
      could you please translate the error message to English?

          Either use 'std::vector' or add 'using std::vector' before this class
          definition. BTW, what book are you reading that doesn't explain 'std'
          namespace and how it's to be used?

          'vector' is undefined. Next time please translate the error message into
          English -- this is an English speaking newsgroup.

              My German stinks -- but my guess is you need

              std::vector

                  Use std::vector.

                  btw, i'm not sure it's a good idea passing two, possibly big,
                  vector<vector<X by value. In particular, it's not a brilliant idea if one
                  of them is supposed to be modified by the method (and you really want the
                  result to reach the caller).
                  I'd use a const reference and a simple reference respectively.

                      I don't understand your language, but it seems you are missing
                      'using namespace std' or you can try 'std::vector' when you use vector
                      in your code.

                          Use std::vector.
                          Yes, of course. I know why I need it, but id did not came to my mind...
                          btw, i'm not sure it's a good idea passing two, possibly big,
                          vector<vector<X by value. In particular, it's not a brilliant idea if one

                          I'd use a const reference and a simple reference respectively.
                          You are absolutely right. I have changed it.
