Give proper indentation to show hierarchy and make code understandable.Write what you mean, not how to program it. It is often used as a tool to help programmers plan and organize their code before they begin writing it in a specific programming language.įollowing are the basic rules before writing pseudocode : In summary, pseudocode is a useful technique for expressing algorithms and program structures in a way that is easy for humans to understand. It is also worth mentioning that there are different conventions for writing pseudocode, as it is not standardized language, so it can be written in variety of styles. Instead, it’s meant to be a helpful tool for humans to plan and understand their programs. It’s important to note that pseudocode is not a programming language and should not be executed by a computer. The key difference is that pseudocode doesn’t have to adhere to strict syntax rules and it can be written in natural language.įor example, the following is a simple pseudocode algorithm that finds the largest value in an array of numbers: The structure of pseudocode can be quite flexible, but it typically follows the basic format of a programming language, with variables, assignments, control flow, and subroutines. It can be used to plan the overall structure of a program, or to work out the details of a particular algorithm or data structure. Pseudocode is often used as an intermediate step between a problem or task description, and the writing of actual code. As such, pseudocode often uses a combination of natural language and programming constructs, such as loop and conditional statements, to convey the overall structure and intent of a program. The purpose of pseudocode is to express the logical steps of an algorithm in a way that is easy for humans to understand, while still being independent of any specific programming language. It is not a formal programming language, but rather a tool that programmers use to plan and organize their code. Pseudocode is a way of describing a computer program or algorithm in plain, easy-to-understand language.
