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.
