- How to initialize array to 0 in C? - Stack Overflow
{0}; works fine, C99 [$6 7 8 21] If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects

- How to initialize a struct in accordance with C programming language . . .
An important thing to remember: at the moment you initialize even one object variable in the struct, all of its other variables will be initialized to default value If you don't initialize the values in your struct (i e if you just declare that variable), all variable members will contain "garbage values", only if the declaration is local!

- c++ - Should I use curly braces, i. e. - Stack Overflow
