Simple C array declaration / assignment question

Question

In higher level languages I would be able something similar to this example in C and it would be fine. However, when I compile this C example it complains bitterly. How can

Answer 1

It is also possible to hide the memcpy by using the compiler's block copy of structs. It makes the code ugly because of all the .i and i: but maybe it solves your specific problem.

typedef struct {
    int i[3];
} inta;

int main()
{
    inta d = {i:{1, 2, 3}};

    if (1)
        d = (inta){i:{4, 5, 6}};

    printf("%d %d %d\n", d.i[0], d.i[1], d.i[2]);

    return 0;
}
