    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.

    Referenced to
    Draft ANSI C Standard (ANSI X3J11/88-090) (May 13, 1988) http://flash-gordon.me.uk/ansi.c.txt


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