The another way is fine :(for C++ ==> g++, gxx)

<--------------------------------------------cut----------------->
#include <iostream.h>

        void display    (long double **,int m, int n);
        void de_allocate(long double **);

        int m = 3;
        int n =5;

int main()
{       long double **data;
        int i,j;

          data=new long double*[m];         /* STEP 1: Set up rows      */
           for(j=0; j < m ; j++)
                data[j]=new long double[n]; /*STEP 2: Set up the columns*/

           for(i=0;i<m;i++)
              for(j=0;j<n;j++)
                data[i][j]=i*j;             /* for example */
           display(data,m,n);
           de_allocate(data);
           return 0;
}
void display(long double **data,int m,int n)
{       int i,j;

        for(i=0;i<m;i++)
        {       for(j=0;j<n;j++)
                { cout<<data[i][j]<<" ";
                }
                cout<<endl;
        }
}
void de_allocate(long double **data)
{       int i,j;
        for(i=0;i<m;i++)
        {       delete[]data[i];   //delete columns
        }
        delete[]data;              //delete rows

}
