Question

Question 21 What will be the results after the following code is executed? int[] arrayi = new int [25]; // Code that will put values in array1 int value = array1[0]; for (int a = 1; a < array1.length; a++) مه if (arrayl[a] < value) value = arrayi[a]; value contains the sum of all the values in arrayi value contains the lowest value in array1 value contains the average of all the values in array value contains the highest value in arzay!

Answer 1

After the above code is executed the result will be:

value contains the lowest value in array1.

​​​​

Explanation:

Let's consider the array1 contains following values [4, 7, 1, 3, 8]

value = array1[0] = 4

Iteration-1

for(a=1 and 1<5 is true)

array[1]<value i.e, 7<4 is false

So the control goes back to for loop

Iteration-2

a++; i.e, 1++

for(2<5 is true)

array1[2]<value i.e, 1<4 is true

So, value = array1[2] = 1

Iteration-3

​​​2++;

for(2<5 is true)

array1[3]<value i.e, 3<1 is false

The control goes back to the for loop

Iteration-4

3++;

for(4<5 is true)

array1[4]<value i.e, 8<1 is false

The control goes back to the for loop

Iteration-5

4++;

for(5<5 is false)

So the control comes out of for loop

And the value = 1(lowest value in array1).

You can refer the executed code with it's output given in the pictures below.
