A transpose of an array is obtained by interchanging the elements of rows and columns. A class Transarray contains a two dimensional integer array of order [ m x n]. The maximum value possible for both ‘m’ and ‘n’ is 20. Design a class Transarray to find the transpose of a given matrix. The details of the members of the class are given below:

Class name :                      Transarray

Data members
arr[][] :                                   Stores the matrix elements
m :                                         Integer to store the number of rows.
n :                                          Integer to store the number of columns.

Member functions
Transarray() :                        Default constructor.
Transarray(intmm,intnn) :      to initialize the size of the matrix, m=mm, n=nn.
Void fillarray() :                      to enter elements into the matrix
void transpose(Transarray A) : to find the transpose of a given matrix.
voiddisaparray() :                  displays the array in a matrix form.

Output:
