Array Output780
What will be the output of the following program?
class ArrayOutput
    public static void main(String s[])
        int[] input = {3, 5, 6, 7};
        int output = multiplyEveryElement(input);
        System.out.print("Result of multiplying every element = " + output + ".");

    public static int multiplyEveryElement(int[] input)
        int result = 1;
        for(int i = 0; i <= input.length - 1; i++)
            result *= input[i];
        return result;

A. Result of multiplying every element = 210.
B. Result of multiplying every element = 90.
C. Result of multiplying every element = 630.

User comments below. All of them might not be correct.

ANS IS C (Result of multiplying every element =630)

--Here,Multiplication of array is done.

--First Array is declared as well as initialized with the elements 3,5,6,7.

--After that,function is called by passing the integer array as a argument.Inside that function FOR LOOPS runs
from 0 to inut.length-1 i.e. 4-1=3 (0 to 3).Inside that loop result variable is multiplied with every element.

Iteration i=0
result=result*input[0]  ----> 1=1*3 ----> 3

Iteration i=1
result=result*input[1]  ----> 3=3*5 ----> 15

Iteration i=2
result=result*input[2]  ----> 15=15*6 ----> 90

Iteration i=3
result=result*input[3]  ----> 90=90*7 ----> 630

--At the end,result is returned to "output" variable and it is printed.
