 Contract: countPassing : double[] int -> double
 Purpose: returns how many grades amongst the first
          size elements of array grades are 73.0 or 
          higher.

 Examples: for double grades[10] = 
           {76.5, 88.0, 99.6, 66, 43.0, 93.2, 73.0, 
            72.0, 74.0, 95},
          countPassing(grades, 10) == 7
