Overload the () operator. Example follow:

#include <iostream.h>

class Test
{
   int x,y;
public:
   void operator() (int, int);
   void disp() { cout << endl << "x: " << x << " y: " << y; }
};

void Test::operator() (int a, int b)
{
   x = a;
   y = b;
}

int main()
{
   Test array[5];

   array[0](1,2);
   array[1](3,4);
   array[2](5,6);
   array[3](7,8);
   array[4](9,10);

   for(int i = 0; i < 5; ++i)
      array[i].disp();

   return 0;
}

HTH, Marco.
