How to declare and initialize a static const array as a class member

Question

Pretty self-explanatory   The array is of an integral type  the contents are known and unchanging  and C  0x isn t allowed   It also needs to be declared as a pointer   I just can t seem to find a syntax that works   The declaration in Class hpp   static const unsigned char  Msg    Stuff in Class cpp is really what I ve tinkered with   const unsigned char Class  Msg 2     0x00  0x01       type mismatch  const unsigned char  Class  Msg   new unsigned char   0x00  0x01       no C  0x       etc   I ve also tried initializing inside the constructor  which of course doesn t work because it s a constant   Is what I m asking for impossible

You are mixing pointers and arrays  If what you want is an array  then use an array   struct test      static int data 10             array  not pointer     int test  data 10      1  2  3  4  5  6  7  8  9  10      If on the other hand you want a pointer  the simplest solution is to write a helper function in the translation unit that defines the member   struct test      static int  data        cpp static int  generate data                   static here is  internal linkage     int   p   new int 10      for   int i   0  i  lt  10    i   p i    10 i     return p    int  test  data   generate data
