Pseudo Code Basics and Rules

Operational Statements

• Include assignment, input, and output processes.
• Control structures enable iterative and conditional execution.
• Indentation is used for grouping blocks of statements.

Rules for Writing Pseudo Code

• Write one statement per line.
• Capitalize initial keywords for clarity.
• Use indentation to show hierarchical structure.
• End multiline structures appropriately.
• Maintain language independence of statements.

Advantages of Pseudo Code

• Can be easily created using any word processor.
• Simple to write and modify compared to flowcharts.

Disadvantages of Flowcharts

• Lack of visual representation may hinder understanding.
• Doesn’t provide a clear picture of the design.

Algorithm vs. Pseudo Code

• Algorithm: A defined procedure allowing a computer to solve a problem.
• Pseudo Code: A simplified method of writing programming code in English, focusing on the implementation of algorithms without syntactical details.
• Algorithms can be described in various forms (e.g., mathematical formulas, graphs), while pseudo code is less detailed.

Algorithm vs. Flowchart

• Algorithm: Step-by-step formation primarily used for program implementation.
• Flowchart: Box-by-box formation useful for general problem-solving.
• Algorithms are more detailed but complex to understand, whereas flowcharts are less detailed but easier to grasp.

Definition of Flowchart

• A flowchart is a pictorial representation of an algorithm using distinct shapes to represent different instructions.

Characteristics of Pseudo Code

• Utilizes named variables for data representation and identifiers for higher-level functions.
• Consists of a sequence of statements or steps.
• Statements are typically numbered sequentially.
• Contains operational statements, control structures, and indentation for organization.

Importance of Flowchart Symbols

• Each shape in a flowchart denotes different types of instructions.
• Using standardized symbols facilitates understanding of program logic.

Rules for Drawing a Flowchart

• Avoid cluttering the flowchart; keep it simple and focused.
• Clearly label all symbols to indicate their functions.

Advantages of Using Flowcharts

• Enhances communication of ideas.
• Aids in effective and proper documentation.
• Facilitates efficient coding and debugging.
• Contributes to smoother program maintenance.

Definition of Pseudo Code

• Combines imitation of coding ("pseudo") with programming instructions.
• Acts as a tool for programming analysis, aiding in planning program logic.

Properties of Algorithms

• Written in simple English for accessibility.
• Each step should be unique and self-explanatory.
• Requires at least one input and one output.
• Comprises a finite number of steps.

Building Blocks of Algorithms

• Sequence: Orders actions in a predetermined manner.
• Selection: Makes decisions based on a question, directing the program to follow different paths.
• Iteration: Repeats actions based on specified conditions.
