Braces around string literal in char array declaration valid? (e.g. char s[] = {“Hello World”})

Question

By accident I found that the line char s[] = {\"Hello World\"}; is properly compiled and seems to be treated the same as char s[] = \"Hello World\";

Answer 1

Any variable in (int, char, etc.) is just an array of length 1.

char s = {0};

works as well.
