Study Notes
Programming Fundamentals
- Programming: a series of instructions to a computer to accomplish a task
- Instructions must be written in a way the computer can understand
- Programming languages are used to write programs
Types of Programming Languages
- High-Level Languages: closer to human language, examples: C#, FORTRAN, PASCAL, PROLOG, JAVA.NET
- Mid-Level Languages: bind the gap between machine level language and high-level languages, examples: C, C++
- Low-Level Languages: deal with hardware registers by name, example: Assembly Language
- Machine Language: the lowest-level programming language, executed directly by a computer's CPU, example: "0110101100101000"
Structured Programming
- A disciplined approach to programming
- Top-down design: a program is divided into a main module and its related modules, each module is divided into sub-modules
- Advantages:
- Easier to understand code
- Easier to test and debug code
- Easier to modify and maintain code
- Easier to work with others on large programs
- 4 Control Structures:
- Sequence
- Selection
- Iteration
- Module
Programming Stages
- The Four Stages of Compiling a C Program:
- Preprocessing: removal of comments, expansion of macros, expansion of included files
- Compilation: compilation of source code into executable instructions
- Assembly: conversion of assembly language's source code into machine language
- Linking: linking of object files into an executable program
Interpreters, Compilers, and Assemblers
- Interpreter: converts source code into machine code, usually on a step-by-step basis, example: BASIC
- Compiler: compiles source code into executable instructions, example: C compiler
- Assembler: converts assembly language's source code into machine language, example: GNU assembler
Test your knowledge on various programming paradigms including Structured Programming, Object-Oriented Programming, Logic/Declarative Programming, and Functional/Applicative Programming. Learn about the key concepts and characteristics of each paradigm.
