how i can call the Row() constructor for this array? is this possible?

#include "stdafx.h"
#include <iostream>
using namespace std;
class Row

private:

}
void Row::Display ()
{
	// example
	cout<<"Display of row class";
}
// Class table
class Table
{
private:
        Row *rows[5];
public:
        Table(int);
};
Table::Table(int a)
{
	// we are not using a here
	for ( int i=0;i<5;i++)
	{
		rows[i]=new Row (5,10);
		rows[i]->Display();
	}
}
int _tmain(int argc, _TCHAR* argv[])
{
	Table t(10);
	return 0;

Somethings seem HARD to do, until we know how to do them.

Row *rows[5];

Table::Table(int a)
{
    rows = new Row[a];
}
