Question

Compute the sum of the values in data_array, instead of using the sum() function. To do this, you must "accumulate" a result, which means that you first create a variable, called data_array_sum, to hold the accumulating result and initialize it to 0. Then loop through your array, updating the accumulating data_array_sum by adding each data_array value as you go: data_array_sum = data_array_sum + data_array(i);

Answer 1

Answer:

public class TestClock {

   public static void main(String[] args) {

       int [] data_array = {1,2,3,5,3,1,2,4,5,6,7,5,4,3};

       int data_array_sum =0;

       for(int i=0; i<data_array.length; i++){

           data_array_sum = data_array_sum + data_array[i];

           System.out.println("Acumulating sum is "+data_array_sum);

       }

       System.out.println("Total sum is: "+data_array_sum);

   }

}

Explanation:

Using Java programming language for this problem, we declare and initialize the array with this statement:

int [] data_array = {1,2,3,5,3,1,2,4,5,6,7,5,4,3};

Then created a variable to hold the sum values and initialize to zero:

int data_array_sum =0;

Using a For Loop statement we iterate through the array and sum up the values.
