The following correctly initializes an array to contain four elements each each with value 0 is I, II and III. 2) Output is 7 and 3) code segment will be printed as a result will be 2, 8, 10, optionD is correct.
The array can be initialized as
1- An array can also be initialized during declaration. ( as in I )
2- In Initializing an array without assigning values, the default value of each element is zero. ( as in II )
3- An array can be initialized by setting each value of an element to zero by looping the length of the array. ( as in III)
I. It creates an array of 4 elements. The default value of int in java is Zero.
II. It also creates an array of 4 elements and manually initialized all the values to 0.
III. It creates an array of 4 elements. and uses a loop to manually initialized all the values to 0.
2) Output is 7 i.e Option(D).
total =total+values[total]; => total = 3+values[3];
=> total=3+(-2) => total=3-2 =>total=1.
total =total+values[total] =>total =1+values[1]
=>total= 1+6 =>total =7.
3)Option(D) i.e 2 8 10.
In If condition it is checking whether the element in the array is Positive and also it is divided by 2 with 0 reminder.
