Study Notes

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.
