Initializing a struct to 0

Question

If I have a struct like this:

typedef struct
{
    unsigned char c1;
    unsigned char c2;
} myStruct;

What would be the easiest way to ini

Answer 1

See §6.7.9 Initialization:

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 that have static storage duration.

So, yes both of them work. Note that in C99 a new way of initialization, called designated initialization can be used too:

myStruct _m1 = {.c2 = 0, .c1 = 1};
