what is the context of a static initializator, and how do I declare a friendship to it?

class test{ static const int veryprivate=3; }; const int anarray[]={test::veryprivate}; g++ smartly points out that anarray is neither a function or a member function. Is it possible to fix this code keeping veryprivate private? C++11…

A better way to initialize a static array member of a class in C++ ( const would be preferred though )

I have a static array of pointers to functions as a member of a class. I need to initialize it, but it turns out this array is 64K items long, so it's impractical to initialize it with a static initializer like { x, y, z, ... } as it would clutter…
