Pseudocode is a methodology used to represent the implementation of an algorithm in a way that can be understood by anyone with basic programming knowledge. It is a description of the steps in an algorithm using a mix of conventions of programming languages, such as assignment operator, conditional operator, and loop, with informal, usually self-explanatory, notation of actions and conditions. Pseudocode is written in a human-readable format, making it easier to edit and discover bugs before actually writing a single line of code. It is often used in textbooks and scientific publications to document algorithms and in planning of software and other algorithms.

Pseudocode is not a programming language, and it has no syntax like any of the programming languages, so it cant be compiled or interpreted by the computer. It is simply an implementation of an algorithm in the form of annotations and informative text written in plain English. Although pseudocode shares features with a regular programming language, it is intended for human reading rather than machine control. It typically omits details that are essential for machine understanding of the algorithm, such as variable declarations and language-specific code.

The advantages of using pseudocode include improving the readability of any approach, acting as a bridge between the program and the algorithm or flowchart, and working as a rough documentation, so the program of one developer can be understood easily when a pseudocode is written out. Pseudocode also provides programmers with a detailed template for writing code in a specific programming language.

There is no one approach to writing pseudocode, nor is there a single set of rules or agreed-upon standard for how to create pseudocode. The primary prerequisite for pseudocode is that its comprehensible to the people who need to understand it, no matter what the codes structure or syntax is.
