2. Psuedo Code
   An almost English way of expressing algorithms.
   if you can't say it, you can't code it!
   
3. Sequence
   
   
4. Selection
   1. Simple if then
   2. If then else
   3. if then multiple steps
   
   
5. Iteration
   1. while loop
   2. do .. while
   3. unstructured loops.

   
   

6. Leap year
   A year that is divisible by 4. But it it is divisible by 100, it must be divisible by 400. 1800 and 1900 not leap years, 2000 is.
   

      Get a Year
      If Year is  evenly divisible by 4?
         If Year is evenly divisible by 100?
           If Year is evenly divisble by 400?
              Print Year is a Leap Year.
           Otherwise
              Print Year is not a Leap Year
           EndIf
         Otherwise 
           Print Year is a leap year.
        EndIf
      Otherwise 
        Print Year is not a leap year.
      EndIf
   
   Leap years 1900 to 2009
        Set the Year = 1900
        While Year is less than 2010
          If Year is  evenly divisible by 4?
             If Year is evenly divisible by 100?
                 If Year is evenly divisble by 400?
                    Print Year is a Leap Year.
                 Otherwise
                    Print Year is not a Leap Year
                 EndIf
             Otherwise 
                Print Year is a leap year.
             EndIf
          Otherwise 
             Print Year is not a leap year.
          EndIf
          Add 1 to Year
        EndWhile
