Is it better style to initialize a structure by passing a reference or returning it?

Question

Say I have the following:

typedef struct {
    int x;
    int y;
    char a;
    char b;
} myStruct;

Is it better practice to create a new

Answer 1

Personally I often use aggregate initialisation for simple data objects:

struct MyStruct {
    int x;
    int y;
    char a;
    char b;
};

int main()
{
    MyStruct s = {10, 20, 'e', 'u'};
}

Or hard coded defaults like this:

struct MyStruct {
    int x;
    int y;
    char a;
    char b;
};

const MyStruct MyDefault_A = {0, 0, 'a', 'z'};
const MyStruct MyDefault_B = {10, 20, 'e', 'u'};

int main()
{
    MyStruct s = MyDefault_A;
}
