The above C declaration define 's' to be

struct node 
{ 
   int i; 
   float j; 
}; 
struct node *s[10];

 

  • A.An array, each element of which is a pointer to a structure of type node
  • B.A structure of 2 fields, each field being a pointer to an array of 10 elements
  • C.A structure of 3 fields: an integer, a float, and an array of 10 elements
  • D.An array, each element of which is a structure of type node.

Answer: A

Correct answer: An array, each element of which is a pointer to a structure of type node

Subscript binds tighter than the dereference, so struct node *s[10] groups as struct node *(s[10]) - an array of 10 pointers, each to a struct node. A pointer to an array would need parentheses in the other place: struct node (*s)[10].
