Fill a double dimensional array of order 4 × 4. Print the left and right diagonal elements of the array.

Answer 1

importjava.util.*;
class Q2
{
    public void main()
    {
       int RC[ ][] = new int [4][4];
       int r = 0, с = 0;
       Scanner sc = new Scanner(System.in);
       for(r = 0; r<4; r++)
    {
       for(c = 0; c < 4; c++)
       {
            System.out.print("Enter value for cell number "+r+""+c+"::");
            RC[r][c] = sc.nextInt();
       }
    }
    System.out.println("\n Printing the left diagonal of the array :");
    for(r = 0; r<4; r++)
    {
            System.out.print(" " + RC[r][r]);
    }
    System.out.println("\n Printing the right diagonal of the array: ");
    for(r = 0; r<4; r++)
    {
          System.out.print(" " + RC[r][3-r]);
    }
  }
}
