About default C struct values, what about this code?

Question

I\'m trying to create structs with default values. I don\'t know how to accomplish this because every code that I see, is about initialising, and I would it for the natural

If you want to set a struct object in one go and you have a C99 compiler, try this:

struct stuff {
    int stuff_a;
    int stuff_b;
    // and so on...
};

struct stuff foo;
/* ... code ... */
foo = (struct stuff){.stuff_b = 42, .stuff_a = -1000};

Otherwise, with a C89 compiler, you have to set each member one by one:

foo.stuff_b = 42;
foo.stuff_a = -1000;

The original line

struct a{   a() : i(0), j(0) {}   INT i;   INT j;}

is a syntax error in C.
