Some specific VC++ information in case that's what you're using:

1. Static class variables construction occurs at same time as other static/global variables.
2. In windows, the CRT startup function is responsible for this construction. This is the actual entry point of most programs you compile (it is the function which calls your Main/Winmain function). In addition, it is responsible for initializing the entire C runtime support (for example you need it to use malloc).
3. The order of construction is undefined, however when using the microsoft VC compiler the order of construction for basic types will be OK, for example it is legal and safe to write

statics.h: ... MyClass declaration ... static const int a; static int b; static int ar[]; } statics.cpp:

const int MyClass::a = 2;
int MyClass::b = a+3;
int MyClass::ar[a] = {1,2}
