C++ Program for transpose of matrix

Transpose of a matrix is a matrix whose columns are rows of original matrix and rows are columns of original matrix.
For example if a matrix m is


                                    1  1  1  1
      m[3][4]  =                2  2  2  2
                                    3  3  3  3
then transpose matrix t will be

                                    1  2  3
   t[4][3] =                     1  2  3
                                    1  2  3
                                    1  2  3
