Study Notes

What is Pseudocode?

Pseudocode is a technique used to describe the distinct steps of an algorithm in a simple and easy-to-understand manner.
It provides a full description of the algorithm's logic, making it easy to translate into code using any programming language's syntax.

Key Features of Pseudocode

Pseudocode is syntax-free, allowing focus on the thought process behind the algorithm.
It uses six core programming constructs (or keywords): SEQUENCE, CASE, WHILE, REPEAT-UNTIL, FOR, and IF-THEN-ELSE.
These constructs describe the control flow of the algorithm and can be used to implement any algorithm.

Benefits of Pseudocode

Pseudocode helps eliminate language syntax limitations, enabling focus on the algorithm's logic.
It makes writing actual code easier, saves time and effort by identifying problems or design flaws early in development.
Pseudocode facilitates communication between programmers and non-programmers (e.g., mathematicians, managers, business partners).
It provides a good starting point for documentation, and can even be included as a docstring at the beginning of the code.

Writing Pseudocode

There is no single style for writing pseudocode, as it is intended for human reading.
However, following simple rules can make pseudocode more universally understood.
Pseudocode should be readable and recognizable, using well-known constructs (keywords) within a field or company.
