Developing Algorithms Using Arrays

AP Computer Science A· difficulty 2/5

int[] a = {2, 4, 6, 8};
int sum = 0;
for (int i = 0; i < a.length - 1; i++) {
  sum += a[i];
}
System.out.println(sum);

What is printed?

A
$12$
check_circle
B
$20$
C
$18$
D
$8$

Explanation

Condition i < a.length - 1 stops at i=2, so a[3]=8 is skipped. Sum is 2+4+6 = 12.
