    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).
