Write definition for a function ADDMIDROW(int MAT[][10],int R,int C) in C++, which finds sum of the middle row elements of the matrix MAT (Assuming C represents number of Columns and R represents number of rows, which is an odd integer). For example, if the content of array MAT having R as 3 and C as 5 is as follows:

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

Write definition for a function SHOWMID(int P[][5],int R,int C) in C++ to display the elements of middle row and middle column from a two dimensional array P having R number of rows and C number of columns.
For example, if the content of array is as follows:

The function should display the following as output :
103 101 121 102 101
116 121 109

Write a function REVCOL (int P[][5], int N, int M) in C++to display the content of a two dimensional array, with each column content in reverse order.
Note: Array may contain any number of rows.
For example, if the content of array is as follows:

The function should display output as:

11      23     61    46    81
13      91     92    87    63
15      12     56    45    51

Write definition for a function UpperHalf(int Mat[4][4]) in C++, which displays the
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

Look at the following C++ code and find the possible output(s) from the
options (i) to (iv) following it. Also, write the maximum values that can
be assigned to each of the variables N and M.

Note:

• Assume all the required header files are already being included in
  the code.
• The function random(n) generates an integer between 0 and n-1

void main()
{
  randomize();
  int N=random(3),M=random(4);
  int DOCK[3][3] = {{1,2,3},{2,3,4},{3,4,5}};
  for(int R=0; R<N; R++)
  {
    for(int C=0; C<M; C++)
      cout<<DOCK[R][C]<<" ";
    cout<<endl;
  }
}

(i)
1 2 3
2 3 4
3 4 5

(ii)
1 2 3
2 3 4

(iii)
1 2
2 3

(iv)
1 2
2 3
3 4

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).
Example: if the content of array MATRIX having N as 5 and M as 3 is as follows:

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

Write definition for a function DISPMID(int A[][5],int R,int C) in C++ to display the elements of middle row and middle column from a two dimensional array A having R number of rows and C number of columns.
For example, if the content of array is as follows:

The function should display the following as output
103 901 921 802 601
516 921 609

Write a function REVROW(int P[][5],int N, int M) in C++ to display the content of a two dimensional array, with each row content in reverse order.
For example, if the content of array is as follows:

The function should display output as:
51 45 56 12 15
63 87 92 91 13
81 46 61 23 81
