Study Notes
Basics of Programming
- A computer program consists of sequential instructions, known as codes, written in a programming language to execute specific tasks.
- Types of software include system software, web browsers, utility software, multimedia software, and spreadsheet software.
- Instructions in a program must generally follow a sequential order unless specified otherwise.
- A programming language is a set of grammatical rules that enables communication with a computer for task execution.
Importance of Programming
- Programming combines art and science to instruct computers on how to perform tasks.
- It enables the creation of solutions to problems through coding.
- Proficiency in programming opens numerous career opportunities in software development, web development, data science, and artificial intelligence.
- Enhances critical thinking, logical reasoning, and problem-solving abilities by breaking complex tasks into manageable steps.
Evolution and History of Programming
- Initial programming involved writing machine code, which consisted of binary instructions (0s and 1s).
- The development of high-level programming languages simplified coding processes, allowing for easier management and control over hardware.
- Low-level programming includes languages like Assembly Language and Machine Language, while high-level languages include C++, Pascal, PHP, Python, and Java.
- Factors influencing the choice of programming language include project requirements, performance needs, community support, and available libraries.
Key Programming Terminology
- Syntax: Refers to the set of rules governing symbols and characters in a programming language.
- Command: Unique instructions for a computer application (e.g., "print" for displaying text).
- Integrated Development Environment (IDE): Software application that formats code, checks syntax, and runs/test code, supporting multiple programming languages or being specific to one.
- Library: Pre-built collection of functions and resources, configured to work together within an IDE.
- Interpreter: Program that directly executes high-level language instructions without conversion to machine language.
- Assembler: Converts low-level assembly code into machine language.
- Compiler: Converts high-level programming languages into machine-readable code.
Algorithm, Pseudocode, and Flowchart
- Algorithm: A set of steps that produces a sequence of computational operations aimed at solving a problem.
- The problem-solving process involves problem analysis, algorithm design, coding, and execution verification.
- Pseudocode: Describes algorithm steps in a simplified manner using common symbols and keywords, making it user-friendly to individuals with basic programming knowledge.
- Example of pseudocode to find the volume of a rectangle:
- READ length
- READ width
- READ height
- COMPUTE volume as length * width * height
- PRINT volume
- Flowchart: A pictorial representation of an algorithm’s steps, illustrating program or system processes using different shapes for various operations.
- There are two types of flowcharts: Program flowcharts (logical steps of a program) and System flowcharts (showing data flow and decision impacts).
- Standard flowchart symbols include:
- Terminal: Indicates start/end of processes.
- Input/Output: Represents input/output operations.
- Computer Processing: Signifies processing tasks.
- Decision: Point where a decision affects the flow of processes.
