Write pseudocode (an outline) for the following:

Read in a sequence of exam scores followed by a -1 to quit. The
program prints the average score (or "no scores entered" if no scores
have been entered).


/* BROKEN VERSION, BUT LOOKS OK */
results = 0
count = 0

while number != -1
  number = getNextScore
  count++ 
  results += number

if count == 0
   print no scores entered
else
   return results / count


What does this code output if the input is:
- just "-1"?
- 100 -1

results: 99
count: 2
number: -1


/* FIXED VERSION */
results = 0
count = 0

number = get first score
while number != -1
  count++ 
  results += number
  number = get next score

if count == 0
   print no scores entered
else
   return results / count
