Study Notes
What is Programming?
- Programming is a multistep process for creating programs through coded instructions for computers.
- It drives innovation and eco-friendly solutions to global challenges.
- Enhances the efficiency of data input and output processes.
- Automates the collection, management, calculation, and analysis of data.
Key Terms in Computer Programming
- Computer Program: A sequence of instructions that directs a computer's operations, written in a programming language.
- Programming Language (PL): A structured code with syntax rules that enables communication with computers to create software.
- Source Code: Set of written instructions in high-level or low-level languages, requiring translation to machine language via translators.
Language Translators
- Assembler: Converts assembly language to low-level language.
- Interpreter: Translates and executes code line by line immediately (e.g., JavaScript, Python).
- Compiler: Translates entire code at once and reports errors simultaneously (e.g., C, C++, Java).
Low-Level vs High-Level Language
- Low-Level Language: Directly linked to specific computer architecture; includes machine and assembly languages, often cryptic.
- Machine Language: The binary code of 0s and 1s representing data and instructions in a computer.
- Assembly Language: Symbolic representation of machine language, using mnemonic codes and labels (e.g., ADD, MUL).
Programming Paradigms
- Procedure-Oriented Programming: Focuses on the sequence of tasks through detailed instructions for execution from start to finish.
- Object-Oriented Programming: Emphasizes the use of objects to achieve program goals, supporting data encapsulation and modularity.
Program Development Life Cycle
- A structured sequence of steps involved in developing software programs:
- Requirement Analysis: Identifying system needs and defining features.
- System Design: Creating algorithms using pseudocode or flowcharts to outline processing steps.
- Coding: Actual programming based on design specifications, adhering to selected programming language syntax.
- Testing and Debugging: Running various tests to ensure program functionality; includes desk checking, debugging, and beta testing with real users.
- Documentation and Maintenance: Preparing detailed program descriptions and user instructions while ensuring ongoing program updates and error rectification.
Testing and Debugging
- Desk Checking: Manual verification of design logic for error-free solutions.
- Debugging: Process of identifying and fixing errors in the code.
- Types of Errors:
- Syntax Error: Incorrect usage of programming language statements.
- Run-time Error: Occurs during program execution.
- Logical Error: Leads to incorrect results or unexpected behavior.
Documentation and Maintenance
- Documentation offers a comprehensive overview of the program and operational guidelines.
- Maintenance involves regularly updating the program to preserve its functionality and performance.
