Question

Write a fragment of code that uses two existing arrays of doubles, a and b, creates a third array c, and assigns each element of c to the average of the corresponding elements of a and b. You may assume that the arrays a and b are the same length. (java)

Question : Write a fragment of code that uses two existing arrays of doubles, a and b, creates a third array c, and assigns each element of c to the average of the corresponding elements of a and b. You may assume that the arrays a and b are the same length. (java)

Program :

public class Sum{
   public static void main(String args[]){
       double a[] = {1.23,2.11,3.54,4.76,5.66,6.78,7.22,8.112,9.10,10.11};        //declaration and intailization of double array a
       double b[] = {11.431,22.129,33.444,44.12,55.32,66.01,77.412,88.432,99.954,1010.123};   //declaration and intailization of double array b
       double c[] = new double[10];     //declaration of double array c
       int i;
       double avg;
       System.out.print(" ");
       System.out.print("Double Array list a : ");
       for(i = 0;i < a.length;i++){
           System.out.print(a[i] + " ");      //printing double array a
       }
       System.out.print(" ");
       System.out.print("Double Array list b : ");
       for(i = 0;i < b.length;i++){
           System.out.print(b[i] + " ");      //printing double array b
       }
       System.out.print(" ");
       for(i = 0;i < a.length;i++){
           avg = (a[i] + b[i])/2;         // assigning each element of c to the average of the corresponding elements of a and b
           c[i] = avg;
       }
       System.out.print("Double Array list c : ");
       for(i = 0;i < c.length;i++){
           System.out.println(c[i]);          //printing double array c
       }
   }
}
