Pseudocode conventions and control structure examples of: if then else, case, while, for, do while and repeat until.

Overview

No standard for pseudocode syntax exists. However, there are some commonly followed conventions to help make pseudocode written by one programmer easily understood by another programmer. Most of these conventions follow two concepts:

  • Use indentation to show the action part of a control structure
  • Use an ending phrase word to end a control structure

The sequence control structure simply lists the lines of pseudocode. The concern is not with the sequence category but with selection and two of the iteration control structures. The following are commonly used ending phrase-words:

Control Structure Ending Phrase Word
If then Else Endif
Case Endcase
While Endwhile
For Endfor

The Do While and Repeat Until iteration control structures don't need an ending phrase-word. We simply use the first word, then the action part, followed by the second word with the test expression. Here are some examples:

Selection control structures

Pseudocode: if then else

If age>17 Display a message indicating you can vote.Else Display a message indicating you can't vote.Endif

nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.
