What a mess! (about structures)

The following is a part of one of my source file:

struct s{char *p};
struct s code a = {"string1"};
struct s code b = {"string2"};

I wonder how the structures, 'a' and 'b', are arranged in the memory on Cx51 chips. Are they placed consecutively in the order as they are declared, while the two strings are placed somewhere else, or 'a' first then "string1", then 'b' and the last "stirng2"?
