Write a program that creates a two dimension matrix of size N x N (N is larger than 4). Through a menu, the user can choose to perform the following operation to the matrix.

1 - Rotate the matrix around the diagonal (function name rotateDiagonal)

Example for 3 x 3 matrix :

1 2 3 - 1 4 7

4 5 6 - 2 5 8

7 8 9 - 3 6 9

2 - Rotate the matrix around the middle row (function name rotateRow)

1 2 3 - 7 8 9

4 5 6 - 4 5 6

7 8 9 - 1 2 3

3 - Rotate the matrix around the middle column (function name rotateColumn)

1 2 3 - 3 2 1

4 5 6 - 6 5 4

7 8 9 - 9 8 7

4 - Set the upper triangle to zero (function name setUpperZero)

1 2 3 - 1 0 0

4 5 6 - 4 5 0

7 8 9 - 7 8 9

Write your program such that the user enters the values of the matrix, and each operation of the above is performed by a function as indicated above. Use the (switch) structure to call the functions.

The user menu can be as follows

1 - Enter Matrix Values

2 - Rotate around Diagonal

3 - Rotate around the middle row

4 - Rotate around the middle column

5- Set the upper triangle to zero

Enter your option ?
