Yes. C spec says
3.5.7 Initialization
Syntax
initializer: assignment-expression { initializer-list } { initializer-list , }
initializer-list: initializer initializer-list , initializer (snip)
If there are fewer initializers in a list than there are members of an aggregate, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

Probably, google "{0}" help your understand to initializer in C.
