Constructing arrays of structs

[Stephen Tashiro via Digitalmars-d-learn]

If the constructor of a class needs to create an array of structs 
whose dimensions are inputs, what's the syntax for doing this?

For a non-example, the following program errors in main() because 
in t.array[][] "index [0] is out of bounds".


import std.stdio;

    struct Point
    {
     uint x;
     uint y;
     void printInfo()
     {
        printf("(%d $d )",x,y);
     }
    }


    class testClass
    {
      uint dimension;
      Point[][] array;

      this(uint the_dimension)
      {
        dimension = the_dimension;
        auto array = new Point[][](the_dimension,the_dimension);
        for(uint i = 0; i < dimension; i++)
        {
           for(uint j = 0; j < dimension; j++)
           {
              array[i][j].x = i;
              array[i][j].y = j;
           }
        }
      }
    }

    void main()
    {
       auto t = new testClass(5);

       for(uint i = 0; i < t.dimension; i++)
       {
          for(uint j = 0; j < t.dimension; j++)
          {
            printf("(%d %d)",t.array[i][j].x, t.array[i][j].y);
             //t.array[i][j].printInfo();
          }

       }

    }
