3. (a) Write the definition of a function AddUp(int Arr[], int N) in C++, in
which all even positions (i.e., 0,2,4,...) of the array should be added
with the content of the element in the next position and odd
positions (i.e., 1,3,5,...) elements should be incremented by 10. 3

Example : if the array Arr contains
23 30 45 10 15 25

Then the array should become

53 40 55 20 40 35

Note :

 The function should only alter the content in the same array.
 The function should not copy the altered content in another
array.

 The function should not display the altered content of the
array.
 Assuming, the Number of elements in the array are Even.

(b) Write a definition for a function SUMMIDCOL(int MATRIX[][10],
int N,int M) in C++, which finds the sum of the middle column‖s
elements of the MATRIX (Assuming N represents number of rows

and M represents number of columns, which is an odd integer). 2
Example : If the content of array MATRIX having N as 5 and M as 3
is as follows :

1 2 1

2 1 4

3 4 5

4 5 3

5 3 2

The function should calculate the sum and display the following :
Sum of Middle Column : 15
