Write a program that creates an integer array with 40 elements in it. Use a for loop to assign values to each element of the arr
iogann1982 [59]

Answer:

public class Main

{

public static void main(String[] args) {

 int[] numbers = new int[40];

 for (int i=0; i<40; i++){

     numbers[i] = i * 3;

 }

 for (int i=0; i<40; i++){

     System.out.println(numbers[i]);

 }

}

}

Explanation:

*The code is in Java.

Initialize an integer array with size 40

Create a for loop that iterates 40 times. Inside the loop, set the number at index i as i*3

i = 0, numbers[0] = 0 * 3 = 0

i = 1, numbers[1] = 1 * 3 = 3

i = 2, numbers[2] = 2 * 3 = 6

.

.

i = 39, numbers[39] = 39 * 3 = 117

Create another for loop that iterates 40 times and prints the values in the numbers array
