**1. **
Write a menu driven C++ program to do following operation on two dimensional array A of size m x n. You should use user-defined functions which accept 2-D array A, and its size m and n as arguments. The options are:

- To input elements into matrix of size m x n
- To display elements of matrix of size m x n
- Sum of all elements of matrix of size m x n
- To display row-wise sum of matrix of size m x n
- To display column-wise sum of matrix of size m x n
- To create transpose of matrix B of size n x m

**2. **
Write user defined functions for square matrix to calculate

- Left diagonal sum
- Right diagonal sum

**3. **
Write a user-defined function in C++ to display the multiplication of row element of two-dimensional array A[4][6] containing integer.

**4. **
Write a user defined function named Upper-half() which takes a two dimensional array A, with size N rows and N columns as argument and prints the upper half of the array.

e.g.,

2 3 1 5 0 2 3 1 5 0

7 1 5 3 1 1 5 3 1

2 5 7 8 1 Output will be: 1 7 8

0 1 5 0 1 0 1

3 4 9 1 5 5

**5. **
Write a function in C++ which accepts a 2D array of integers and its size as arguments and displays the elements of middle row and the elements of middle column.

[Assuming the 2D Array to be a square matrix with odd dimension i.e. 3x3, 5x5, 7x7 etc...]

Example, if the array contents is

3 5 4

7 6 9

2 1 8

Output through the function should be :

Middle Row : 7 6 9

Middle column : 5 6 1

**6. **
Write a program to add two array A and B of size m x n.
