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.
