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);
