Complete the following program so that it computes the sum of all the elements of the array, the sum of the even elements, and the sum of the odd elements. code example

Example 1: how to add up all numbers in an array

var numbers = [10, 20, 30, 40] 
var sum = 0;
for (var i = 0; i < numbers.length; i++) {  sum += numbers[i]}

Example 2: sum of arrays

/**
 * C program to find sum of all elements of array
 */

#include <stdio.h>
#define MAX_SIZE 100

int main()
{
    int arr[MAX_SIZE];
    int i, n, sum=0;

    /* Input size of the array */
    printf("Enter size of the array: ");
    scanf("%d", &n);

    /* Input elements in array */
    printf("Enter %d elements in the array: ", n);
    for(i=0; i<n; i++)
    {
        scanf("%d", &arr[i]);

        // Add each array element to sum
        sum += arr[i];
    }

    printf("Sum of all elements of array = %d", sum);

    return 0;
}

Example 3: sum of arrays

/**
 * C program to find sum of all elements of array 
 */

#include <stdio.h>
#define MAX_SIZE 100

int main()
{
    int arr[MAX_SIZE];
    int i, n, sum=0;

    /* Input size of the array */
    printf("Enter size of the array: ");
    scanf("%d", &n);

    /* Input elements in array */
    printf("Enter %d elements in the array: ", n);
    for(i=0; i<n; i++)
    {
        scanf("%d", &arr[i]);
    }

    /*
     * Add each array element to sum
     */
    for(i=0; i<n; i++)
    {
        sum = sum + arr[i];
    }


    printf("Sum of all elements of array = %d", sum);

    return 0;
}
