Pseudocode is a method of writing down the logic and steps of an algorithm in plain, human-readable language. It is not bound by any programming language syntax. Pseudocode bridges the gap between the I: EP D:M G thought process and the actual coding.  Why U se Ps e ud o co d e ? Clarifies Thinking: Helps programmers and non-programmers map out the steps of an algorithm before coding. Eases Collaboration: Enables effective communication between team members, especially if they are using different programming languages. Simplifies Debugging: Offers a clear picture of the algorithm, making it I: EP easier to spot mistakes in logic early. D:M G  Pse ud oc od e Ch a ra c t e ri st ics Simple Language: Written in plain language (English-like). No Specific Syntax: Does not follow strict programming syntax, unlike actual code. Readable: Should be easy to understand for both technical and non-technical stakeholders. Uses Standard Constructs: Includes common structures like loops, I: EP D:M conditionals, and variables. G  Pse ud ocod e v s. Pro g ra mmi ng Cod e Pseudocode: High-level and abstract representation of logic; not meant to run on a computer. Code: Written in a specific programming language with syntax that can be compiled or interpreted. Pseudocode helps to think through the process, while real code is for execution. I: EP D:M G  Writing Eff e ct i v e Ps e ud o cod e Break Down Tasks: Divide the algorithm into small, manageable steps. Use Clear Language: Avoid complex terms or ambiguity. Be Consistent: Use similar terminology and structure throughout the pseudocode. Avoid Code-Like Syntax: Focus on describing the logic, not the syntax. I: EP D:M G  Ba sic Con st ru ct s i n Ps e ud ocode Variables: Use simple assignments (e.g., Set X = 10). Conditionals: Use clear IF-THEN-ELSE structures. Loops: Represent loops in a readable way, such as FOR, WHILE, or REPEAT. Input/Output: Use terms like "Input", "Output", or "Display". I: EP D:M G  S impl e Ex a mp l e of Pse u d ocod e Task: Calculate the sum of two numbers. Pseudocode: START Input A Input B Set SUM = A + B Output SUM END I: EP D:M G  Whe n t o U s e Ps e u d oc od e During Planning: Before coding, to map out the flow and logic. For Explanation: To explain complex algorithms in meetings or documentation. Before Testing: To ensure the logic is sound before writing code. For Beginners: To teach programming concepts without introducing complex syntax. I: EP D:M G  Ti ps for Wri t i n g Ps e u d o cod e Start High-Level: Begin with the broad steps before detailing specific actions. Use Meaningful Names: Choose names for variables and steps that describe their function (e.g., Total, Max, Average). Be Consistent: Stick to a similar format throughout the pseudocode. Use Indentation: Indent structures like loops and conditionals for better I: EP D:M readability. G TUTORIAL I: EP D:M G
