Using Direct Input Method
In this method, the values to be inserted are taken in as parameters by the user.
Program 20 Create an array of size 4 × 4, take values using parameter and display the diagonals and also
display the sum of numbers present in the diagonal position.

5 int i, j, sum = 0;
6 for(i = 0; i<4; i++)
7 {
8 for(j = 0; j<4; j++)
9 {
10 if(i == j || (i+j) == 3)
11 {
12 System.out.print (a[i][j]+" ");
13 sum += a[i][j];
