When initializing a char array, is the remaining space zero filled or uninitialized?

Question

Given

char foo[1024] = \"bar\";

This will initialize foo to contain \'b\',\'a\',\'r\',0 . Is the remaining 1020 characters zero initialized

Answer 1

If an array/aggregate is initialized somehow[edit: by use of a static initializer], the remaining unspecified entries are zeroed, yes.
