You can avoid the warning by using completely empty braces:

STRUCTA array[10] = {};

The array will be aggregate-initialized, which means that each of the structs in it will in turn be value-initialized. Value-initialization with empty brackets turns into aggregate-initializion of each struct, which sets all fields to 0, which is what you want.

This works in all cases as long as your structs are POD (see the links above for precise description).
