C Quiz - 112 | Question 3

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.
