struct xx

{

      int x=3;

      char name[]="hello";

 };

struct xx *s;

printf("%d",s->x);

printf("%s",s->name);

}

Compiler Error

Explanation:

Do variables need to be initialized?

No. All variables should be given a value before they are used, and a good compiler will help you find variables that are used before they are set to a value. Variables need not be initialized, however.

Automatic variables are variables defined inside a function or block
