My struct is as follow.
typedef struct user {
char *name;
int age;
} User;
Now when I am creating an array, I wonder what is the different between below both statments.
User users[10];
vs
User users[10] = {};

1If `users` has static linkage, there is no difference. If it is an automatic variable, the former's content is indeterminate, the latter is zero-filled. – WhozCraig Mar 11 '14 at 08:14

@BLUEPIXY true that. I assumed the OP was using the GNU initialization extension. – WhozCraig Mar 11 '14 at 08:22

The first (User users[10];) do not erase the flash or memory so it is possibel that you have things on this memory from the Programm befor
