Thread: Structure question

Code:

struct address {
    int street_no;
    char *street_name;
    char *city;
    char *prov;
    char *postal_code;
    };

Code:

struct address{
   int street_no;
   char street_name[20];
   char city[20];
   char prov[20];
  char postal_code[20];
};

What is the difference between the two declerations??
Can the pointer variable be something other than char ?? like (int,float,double)??

The difference between them is that in the second case, the storage for the strings is provided in the struct itself; in the first case, all you have is a pointer and for every address you must malloc (or otherwise provide) storage space for the strings.
