Pick the best statement for the below program:




#include "stdio.h"
  
int main()
{
 struct {int a[2], b;} arr[] = {[0].a = {1}, [1].a = {2}, [0].b = 1, [1].b = 2};
  
 printf("%d %d %d and",arr[0].a[0],arr[0].a[1],arr[0].b);
 printf("%d %d %d\n",arr[1].a[0],arr[1].a[1],arr[1].b);
  
 return 0;
}


(A) Compile error because struct type (containing two fields i.e. an array of int and an int) has been specified along with the definition of array arr[] of this struct type.
(B) Compile error because of incorrect syntax for initialization of array arr[].
(C) No compile error and two elements of arr[] would be defined and initialized. Output would be “1 0 1 and 2 0 2”.
(D) No compile error and two elements of arr[] would be defined and initialized. Output would be “1 X 1 and 2 X 2” where X is some garbage random number.


Answer: (C)

Explanation: In C, designators can be used to provide explicit initialization. For an array, elements which aren’t initialized explicitly in program are set as ZERO. That’s why correct answer is C.
