Question

TOUTUU BULUTONOLIO Evaluate the fragmented code and determine the required output int[] arr = new int [4]; for (int i = 0; i < 4; i++) if (i % 2 == 0) arr[i] = 2 * i; else arr[i]=i; (Each Question values 3 points total 12 points) What value is assigned to arr[0]? What value is assigned to arr[ 1 ]? What value is assigned to arr[2]? What value is assigned to arr[ 3 ]?

java arrays

Answer 1

Answer:

for i=0,

i%2 == 0 will return true and if statement will execute

Then, arr[i] = 2*i

arr[0] = 2*0 = 0, => arr[0] = 0

for i=1,

i%2 == 0 will return false and else statement will execute

Then, arr[i] = i

=> arr[1] = 1

for i=2,

i%2 == 0 will return true and if statement will execute

Then, arr[i] = 2*i

arr[2] = 2*2 = 4, -> arr[2] = 4

for i=3,

i%2 == 0 will return false and else statement will execute

Then, arr[i] = i

=> arr[3] = 3

So, finally following value will be assigned to the array-

arr[0] = 0

arr[1] = 1

arr[2] = 4

arr[3] = 3
