What does this code do?



 void PickRandomNumbers()

 {

 int intNumber1;

 double dblNumber;

 int intNumber2;

 Random objRandom = new Random();



 intNumber1 = objRandom.Next();

 dblNumber = 5 * objRandom.NextDouble();

 intNumber2 = objRandom.Next( 1, 10 );



 lblInteger1.Text = Convert.ToString( intNumber1 );

 lblDouble1.Text = Convert.ToString( dblNumber );

 lblInteger2.Text = Convert.ToString( intNumber2 );



 } // end method PickRandomNumbers

intNumber1 gets a positive integer (between 0 and Int32.MaxValue), dblNumber

gets a floating-point number between 0 and 5 (not including 5) and intNumber2 gets an integer between 1 and 10 (not including 10). The complete code reads:
