representation of MAC address in C code

问题

I often see such representation of MAC address in C code:

struct mac_addr {
   unsigned char bytes[6];
}

Why necessary put an array in a structure, why not just have an array? What benefit does this provide?

Thanks.

You can't assign an array in C. But you can assign a struct.
