// Contract: fillArray2 : &double[] &int -> void
// Purpose: ask the user how big of an array of double
//          that he/she wants, then set arrToFill to
//          point to that array and ask the user for
//          that many values, to fill it. Also, set 
//          desiredSize to be the size of the new array 
//          (the size the user entered)

// I need the address of a pointer --- so I can set
