Answer 2

The output of the given program if the array begins at 1000 and each integer occupying 2 bytes will be 1004 1008. Hence, option(d) is the correct answer.

• In any 2 dimensional array, "pointer to an array of 2 ints" is used as a reference to the array.
• The pointer to the first element of the 2nd row of an array will be arr+1 and its location will be 1000 + 2*2 = 1004.
• &arr is a type of "pointer to an array of 2 arrays of 2 ints" that will be 4 ints.
• &arr+ 1 will point to the location 1000 +4 *2 = 1008
