Hierarchy Charts Good for showing the structure of the
algorithm

Hierarchy Charts Good for showing the structure of the
algorithm Good at breaking down the algorithm into
components

Hierarchy Charts Good for showing the structure of the
algorithm Good at breaking down the algorithm into
components Not too great at showing the order of events

Hierarchy Charts Good for showing the structure of the
algorithm Good at breaking down the algorithm into
components Not too great at showing the order of events Flow Charts are better at showing the order in
which the components execute.

Pseudocode This will become more clear when you
understand VB terms better.

Pseudocode This will become more clear when you
understand VB terms better. Pseudocode is good for listing the steps of an
algorithm in a form that is easier to translate into VB.

Pseudocode This will become more clear when you
understand VB terms better. Pseudocode is good for listing the steps of an
algorithm in a form that is easier to translate into VB.
Important: There is NO SPECIFIC FORM to pseudocode, it can look as much like VB or English as you want. The more VB you learn, the more VB-like pseudocode you can write.
