1.3.2 Algorithm Development using Pseudocodes



Pseudocode, also called Program Design Language (PDL) is most widely used to develop algorithms that represent a logic of a computer program. Pseudocode allows a program to represent the logic of a program in an English-like manner.


There are rules to be followed when using Pseudocode. However many versions of Pseudocode exist and there is no industry standard. The rules described below are adhered to by most organizations that use Pseudocode.


  • The Pseudocode must be language independent. Try to avoid the use of words peculiar to any programming language.
  • Indent lines to make the Pseudocode easy to read and understand.
  • Punctuation is optional
  • Every IF must be with an ENDIF.
  • Every DO WHILE must end with END DO.
  • Show keyword in CAPITAL LETTERS

         e.g. IF marks >= THEN
                    DISPLAY "Pass"
                ELSE
                    DISPLAY "Fail"
                ENDIF
