I int [] arr = {0, 0, 0, 0};

II int [] arr = new int [4];

III int [] arr = new int [4];

for (int i = 0; i < arr. length; i ++)

arr [i] = 0;

A.	I only	B.	III only
C.	II and III only	D.	I, II, and III

51.

What will be the output of the program if the array begins 1200 in memory?

#include

int main()

{

int arr[]={2, 3, 4, 1, 6};

printf("%u, %u, %u\n", arr, &arr[0], &arr);

return 0;

}

A.	1200, 1202, 1204	B.	1200, 1200, 1200
C.	1200, 1204, 1208	D.	1200, 1202, 1200

52.

the following program segment is intended to find the index of the first negative integer in arr [0] ... arr [ N-1], where arr is an array of N integers.

int i = 0;

while (arr [i] >= 0)

{

i++;

}

location = i ;

This segment will work as intended

A.	Always	B.	Never
C.	Whenever arr contains at least one negative integer	D.	Whenever arr contains at least one nonnegative integer

53.

What will be the output of the program if the array begins at 65472 and each integer occupies 2 bytes?

#include

int main()

{

int a[3][4] = {1, 2, 3, 4, 4, 3, 2, 1, 7, 8, 9, 0};

printf("%u, %u\n", a+1, &a+1);

return 0;

}

A.	65474, 65476	B.	65480, 65496
C.	65480, 65488	D.	65474, 65488

54.

Refer to the following code segment. You may asume that arr is an array of integers.

int sum = arr [0], i = 0;

while (i < arr. length)

{

i++;

sum+= arr [i];

}

Which of the following will be the resul of executing the segment?

A.	Sum of arr [0]. arr[1],..., arr [arr.length-1] will be stored in sum	B.	Sum of arr [1], arr[2],..., arr [arr.length-1] will be stored in sum
C.	Sum of arr [0], arr[1],..., arr [arr.length] will be stored in sum	D.	A run-time error will occur
