(½ Mark for adding odd elements)
(½ Mark for displaying the sum of even and odd elements)

(b) Write definition for a function ​UpperHalf(int Mat[4][4]) in C++, which displays the 3
elements in the same way as per the example shown below.
For example, if the content of the array Mat is as follows:
25 24 23 22

20 19 18 17
15 14 13 12

10 9 8 7
The function should display the content in the following format:
25 24 23 22
20 19 18

15 14
10

Ans void UpperHalf(int Mat[4][4])
{
for (int I=0;I<4;I++)
{
for (int J=0;J<4-I;J++)
cout<<MAT[I][J]<< " " ;
cout<<endl;
}
}
OR
void UpperHalf(int Mat[4][4])
{
for (int I=0;I<4;I++)
{
for (int J=0;J<4;J++)
if ((I+J)<=3)
cout<<MAT[I][J]<< " " ;
cout<<endl;
}
}
OR
Any other correct alternative code in C++

(½ Mark for correctly writing loop for traversing rows)
(½ Mark for correctly writing loop for traversing columns in each row)
(1 Mark for correctly checking elements for display)
(½ Mark for correctly displaying the selected elements)
(½ Mark for correctly displaying line break after each row)

(c) Let us assume Data[20][15] is a two dimensional array, which is stored in the 3
memory along the row with each of its element occupying 2 bytes, find the
