3.3.11.Using the break statement to avoid repeating code in the class-average program.

# initialization phase

total = 0          # sum of grades

gradeCounter = 0   # number of grades entered



while 1:

   grade = raw_input( "Enter grade, -1 to end: " )   

   grade = int( grade )



   # exit loop if user inputs -1

   if grade == -1:

      break



   total += grade

   gradeCounter += 1

   

# termination phase

if gradeCounter != 0:

   average = float( total ) / gradeCounter

   print "Class average is", average

else:

   print "No grades were entered"
