Programming-wk4

• Programming

  The process of creating instructions that a computer can follow to perform a specific task, written in a programming language which is a formalized set of rules and syntax that allows humans to communicate with computers
• Goal of programming

  To design and implement algorithms, logic, and data structures to solve a particular problem or automate a specific set of tasks
• Programming Language

  A formalized set of rules and syntax that allows humans to communicate instructions to a computer, serving as an intermediary between the human programmer and the computer
• Programming

  The process that results in the development of a set of detailed instructions following a pattern of a particular programming language necessary to solve a problem
• Programming languages are used to write code, which is then translated or compiled into machine code that a computer can execute
• Levels of Programming language

  • Machine Language
  • Low Level Language
  • High Level Language
• Machine Language


  The lowest level of programming language, consisting of binary code that the computer's central processing unit (CPU) can directly execute, with each instruction corresponding to a specific machine operation
• Low Level Language


  Consists of binary code directly understandable by a computer's central processing unit (CPU) and mnemonic codes and symbols to represent machine-level instructions, making it more human-readable than machine language
• High Level Language


  A programming language designed to be easy for humans to read and write, providing a higher level of abstraction from the hardware, allowing programmers to write code that is more readable, understandable, and independent of the hardware
• High-level language


  A programming language designed to be easy for humans to read and write, providing a higher level of abstraction from the hardware
• High-level languages


  • Closer to natural language, more user-friendly, making it easier for developers to express their ideas and algorithms in a form closer to human thinking
• High-level programming languages

  • Python: Known for readability and versatility
  • Java: Versatile, object-oriented, platform-independent
  • C#: Used for building Windows applications, web applications, and game development
  • JavaScript: Primarily used for web development
  • Ruby: Object-oriented, often used for web development
• Other high-level languages

  • BASIC
  • FORTRAN
  • COBOL
  • PASCAL
• Formal constructed language designed to communicate instructions to a machine is a programming language
• The language the computer understands is called machine language
• Binary digits 0s and 1s are involved in low-level language
• Examples of high-level programs exclude FORTRAN, COBOL, JAVA, D++
• Programming can be defined as the process that results in the development of detailed instructions in a programming language to solve a problem
