Programming languages

Programming languages

1. High-level language

   • Python
   • JavaScript
   • C++
   • One instruction = many instructions of machine code
   • The same code will work for many different machines and processors.
   • Code is easy to read and understand by humans.
   • Must be translated into machine code before a PC is able to understand it.

2. Low-level languages

   • Machine code
     • Binary
   • assembly code
     • mnemonics
       • Shortened instructions
   • 1 instruction of assembly code = 1 instruction of machine code
   • Written for one type of machine or processor and won't work on any other.
   • Code is very difficult to understand and read by humans.
   • Commands in machine code can be executed directly without the need for a translator.

3. DICE

   • Debugger
     • Identifies errors in your code and can highlight the location of the error/reason/suggestions on how to fix the error.
   • Interpreter
     • Allows you to translate source code line by line when testing your code.
   • Compiler
     • Converts the source code into machine code so that it can be executed as a stand-alone program file.
   • Editor
     • Write/edit code, colour code keywords, autocomplete code.
