(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.
