Study Notes
Algorithm
- A systematic procedure for solving problems or performing computations.
- Functions as a step-by-step guide in both hardware and software contexts.
- Everyday examples include:
- Tying shoes
- Following recipes
- Classifying objects
- Bedtime routines
- Locating library books
- Navigating (driving directions)
- Deciding meals
Pseudocode
- A method for writing algorithms using natural language, typically English.
- Intended for human readability, it cannot be compiled or executed.
- Also referred to as "false code."
- Guidelines for writing pseudocode:
- Start with a clear goal statement.
- Arrange tasks in sequence.
- Indent control structures like if-else and loops for clarity.
- Use meaningful and distinct names to enhance understanding.
- Employ standard programming structures (e.g., if-then, for, while, cases).
- Ensure pseudo code is simple and comprehensible to non-technical users.
- Avoid overly technical terms and keep it clear and finite.
Flowchart
- A visual representation of a process, system, or algorithm.
- Illustrates a program's functions in sequence, separate from the data processed.
- Serves as a graphical tool to understand actions and decision processes within a program.
Flowchart Examples
- Design a flowchart for displaying "Hello World."
- Create a flowchart that adds two user-inputted numbers.
- Construct a flowchart to evaluate whether a user's grade is a "pass" or "fail" (passing grade is 75).
