Study Notes
Programming Essentials
- Programming: A multistep process for creating a program.
- Code: Instructions that guide a computer's actions.
- Eco-friendly Innovation: Programming is crucial for developing sustainable solutions to global challenges.
Understanding Computer Programs
- Computer Program: A structured sequence of instructions directing computer functions.
- Importance of Programming: Enhances the speed of input and output processes in machines.
Programming Languages
- Programming Language (PL): A written language instructing computers on how to operate.
- Syntax: Each PL has its unique set of grammatical rules governing the statement structure.
Roles in Programming
- Programmer: An individual who writes source code using a programming language.
- Source Code: A well-crafted set of instructions and statements intended for program development.
Language Types
- Low Level Language: Offers direct instructions tied to specific computers, often cryptic and not human-readable.
- High Level Language: Utilizes English-like instructions, compatible across various computer types.
- Examples of High Level Languages: Visual Basic, C, C++, Java.
Machine Languages
- Machine Code: Data in a computer represented by electronic switches (0s and 1s).
- Assembly Language: A symbolic programming language representing opcodes and memory addresses.
Translation Tools
- Language Translator: Converts source code to machine language via assemblers, interpreters, or compilers.
- Assembler: Translates assembly language programs into machine instructions.
- Interpreter: Translates and executes each statement one line at a time.
- Compiler: Processes all statements simultaneously, providing comprehensive error messages.
Programming Approaches
- Procedure-oriented Programming: Focuses on major tasks with detailed procedural instructions from start to finish.
- Object-oriented Programming: Concentrates on utilizing objects to achieve program goals, allowing diverse forms.
Program Development Cycle
- Stages: Requirement Analysis, System Design, Coding, Testing and Validation, Documentation and Maintenance.
- Requirement: A description of the system's intended functionalities.
- Requirement Analysis: Gathering information to define the characteristics of the desired system.
Problem Analysis Process
- Steps: Define the problem and users, determine outputs and inputs, establish processes, assess feasibility, document the analysis.
Algorithm Development
- Algorithm: A step-by-step sequence detailing how data processing will achieve the desired output.
- Formulating Algorithms: Can utilize pseudocodes or flowcharts as methods for planning.
Pseudocode
- Pseudocode: An algorithm expressed in normal human language for easier understanding and reference.
