C: How does nested braces for array of struct initialization work? -

- 

struct mystruct s[10] = {{0}};

any fields not specified initialized zero. here have array of structs. you're initializing first element of array structure initializer initializes first element of structure zero. rest of first structure , rest of array elements 0 too. it's nice idiom.
