2c(2) states:

Array initializers can specify the indices of the array in

This is somewhat confusing: the third and the tenth element should have
index 2 and 9. Moreover if the tenth element is actually referred by index
10, why the array should hold eleven elements?

A simple check shows that actually the array has 11 elements and the one
initialized are the forth and the eleventh.
