    Study Notes

    Introduction

    • Intelligence distinguishes humans from other creatures.
    • Basic intelligence involves solving everyday problems and creating strategies.
    • An example of basic intelligence is deciding how much money to withdraw from a bank account.
    • Problem-solving involves identifying necessary steps to achieve a goal.

    Problem Solving

    • Problem-solving is an integral part of everyday activities.
    • Any action taken to achieve a specific objective can be considered problem-solving.

    Algorithm

    • An algorithm is a set of instructions for solving a problem.
    • An algorithm must be unambiguous and have a clear stopping point.
    • An algorithm takes input, performs operations, and produces output.
    • Examples of basic operations in algorithms include addition, subtraction, multiplication, division, and assignment.
    • Before writing an algorithm, identify the input and expected output.

    Example of Algorithm

    • Problem 1: Calculate the area of a circle given its radius.
      • Input: Radius (r)
      • Algorithm:
        • Read the radius (r).
        • Calculate the area (Area = Pi * r * r).
        • Print the area.

    Properties of Algorithm

    • Finiteness: An algorithm must terminate after a finite number of steps.
    • Definiteness: Each step of an algorithm must be precisely defined.
    • Input: An algorithm requires input values to start the process.
    • Output: An algorithm produces output values that are related to the inputs.
    • Effectiveness: Each step in an algorithm must be basic and achievable using simple operations.

    Flowchart

    • A flowchart is a visual representation of the flow of data through a process.
    • Flowcharts help understand the operations and their sequence within a system.
    • Flowcharts are used to represent algorithms.
    • A flowchart is like a blueprint for solving a problem.
    • Standardized flowchart symbols are used to represent different types of operations.

    Flowchart Symbols

    • Terminal: Represents the start and end of a flowchart.
    • Process: Indicates any internal operation within the processor or memory.
    • Input/Output: Represents input or output operations, such as reading data or printing results.
    • Decision: Represents a question with a yes/no or true/false answer, branching the flow based on the answer.
    • Connector: Used to connect separate parts of the flowchart.
    • Predefined Process: Represents a subroutine or interrupt program.

    General Rules for Flowcharting

    • Use arrows to connect flowchart symbols.
    • Each symbol has one entry point at the top and one exit point at the bottom (except the decision symbol).
    • The decision symbol has two exit points.
    • Generally, flowcharts flow from top to bottom, but upward flow is allowed with limitations.
    • Connectors are used to connect breaks in the flowchart.
    • Subroutines and interrupts have their own independent flowcharts.
    • Flowcharts begin with a terminal or predefined process symbol.
    • Flowcharts end with a terminal or a continuous loop.

    Advantages of Using Flowcharts

    • Clear visual representation: Flowcharts visually represent algorithms, making them easier to understand.
    • Documentation: Flowcharts serve as documentation for programs.
    • Communication tool: Flowcharts facilitate communication about program logic.
    • Problem-solving aid: Flowcharts can help identify potential problems in the logic of a program before implementation.
