    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.
