What is Pseudocode

As you know, pseudocode is the way of expressing a program or code so that it could be easily understood by programmers of every programming languages out there.

Pseudocode is an informal high-level description of the operating principle of a computer program or an algorithm

For example, a print is a function in python to display the content whereas it is System.out.println in case of java, but as pseudocode display/output is the word which covers both the programming languages.




So that the programme written in an informal language and could be understood by any programming background is pseudocode.

Hence we can say that the purpose of writing pseudocode is that it is easier for people to understand than any specific programming language code

No standard for pseudocode syntax exists, as a program in pseudocode is not an executable program.

Following are the basic rules before writing pseudocode :

  • Write only one statement per line.
  • Write what you mean, not how to program it
  • Give proper indentation to show hierarchy and make code understandable.
  • Make the program as simple as possible.
  • Conditions and loops must be specified well ie. begun and ended explicity as in given pseudocode examples :
