What's Wrong With This Code? (#8)

Tuesday, October 24, 2006

Joe Developer is working with a simple struct:

struct Point

{

    public int x;

    public int y;

}

Joe's tech lead asked him to write a method that will return an array of 10,000 initialized points. Joe wrote following code.

Point[] CreatePoints()

{

    Point[] points = new Point[10000];

    for (int i = 0; i < points.Length; i++)

    {

        points[i] = new Point();

    }

    return points;

}

The code doesn't create any runtime errors, but Joe is worried because his tech lead looked at the code and frowned. What could provoke such a reaction?

Hint: Joe's lead is a performance nut.
