Write an algorithm to ask the user for a number and then to print all 
the numbers from 1 to the entered number. 


   input identifiers : number
   output identifier : counter
   others : none


   comment: declare variables
      number=0
      counter=0

   comment : get the input
      print "Enter a positive number -- "
      get number

   comment : loop to print the number from 1 to number
      counter = 1       comment: start printing at 1
      repeat while counter is less than or equal to number
             print counter " "
             counter = counter+1



Write an algorithm that repeatedly asks the user for a character until the user
enters a period (.).  After the period is entered the algorithm reports the 
number of characters entered.


    input identifiers : character
    output identifiers : howMany
    others : none

    comment: declare variables
       character=' '
       howMany=0

    comment: get the initial input
       print "Enter a character -- "
       get character

    comment: loop counting the character and getting another until a . is found
       repeat while character is not equal to a .
              howMany=howMany+1
              print "Enter a character -- "
              get character

    comment: now display the result
       print "You entered " howMany "characters."




Write an algorithm to ask the user for two numbers and then print all the 
numbers from the first to the second inclusive.

 
    input identifiers : first second
    output identifiers : current
    others : none

    comment: declare variables
       first=0
       second=0
       current=0

    comment: get the input
       print "Enter first number -- "
       get first
       print "Enter the second number -- "
       get second

    comment: loop to print the numbers from first to second
       current=first          comment: start printing at first
       repeat while current is less than or equal to second
              print current
              current = current+1



Write an algorithm which asks the user for a number and prints the number
in reverse order.


   input identifiers : number
   output identifiers : digit
   others : none

   comment: declare variables
     number=0
     digit=0

   comment : get input
      print "Enter a positive number -- "
      get number

   comment: use remainder and divide to get the digits one at a time and print
   comment: note the last digit can be obtained by finding the remainder when
   comment: the number is divided by 10. We can then divide the number by 10 to
   comment: remove the last digit. We will repeat this until the number is 0
   while number is not equal to 0
         digit = number%10   comment: this will get the last digit
         print digit
         number = number/10  comment: this removes the last digit
