#Additional algorithm 22. Here the positive increment while-loop structure is demonstrated. A variable i is declared and set to zero. A while loop structure increments variable i from its initial value to its upper limit (number five). At each iteration, variable i is printed in the output. The result is an enumeration of values from 0 to 4. Note that the source code is in context and works with copy/paste.

i = 0

while i < 5:
  print('i = ' + str(i))
  i += 1
