Need help in dynamic memory alloction of multi-dimensional array

Hi everybody,

Thanks for helping, and appreciate if you could help in this problem.

When I used the 2 following lines in a simple code, the code will compile
with no error:

long (*pprime)[max2];

pprime = new long[max][max2];

But if I separate the two lines by putting the first in a class

and the second line in the constructor of the same class I will have the
under mentioned error messages.

Can you tell me what is wrong and how I can do it right?

#include <iostream>

using namespace std;

    const int max = 5;

      const int max2 = 4;

class Array

{

public:

  long (*pprime)[max2];

  int capacity;

  int capacity1;

  Array(int max, int max2)

  { capacity = max;

     capacity1 = max2;

       pprime = new long[max][max2];
<------------------------------------------error

       //error(1) C2540: non-constant expression as array bound

     //error (2)C2440: '=' : cannot convert from 'long (*)[1]' to 'long
(*)[4]'

  }

};

int main()

{

  return 0;

}
