Programming languages

1. IDE

   • Features of an IDE
     • Editor
       • The editor allows you to write and edit code. This is made easier by having auto-complete, auto-colour and auto-indent
         • Auto colour codes key command words
     • Translator - translates high level code to low level code
       • Interpreter
         • A interpreter translates high level code into low level code line by line
       • Compilers
         • A compiler translates high level code into low level code in one go
       • Assembler
         • Uses mnemonics to shorten function to make writing and reading easier for example LDA is short for load
           • Mnemonics
             • ADD - Addition
             • SUB - Subtraction
             • STA - Store
             • DAT - Data
             • HLT - Halt program
     • Error Diagnosticts
       • Scans for any syntax errors the user may have made
       • A compiler do not check the code whereas the interpreter checks code line by line
     • Run Time Environment
       • Where your code is ran with in a IDE. This is quicker than compiling the code because the Run Time Environment is built into the IDE
   • IDE stands for Integrated Development Environment
   • Examples include IDLE and Pycharm

2. High level programming language

   • Designed to be understood by humans
     • Javascript
     • Scratch
     • Python

3. Low level programming language

   • Designed for computers
     • Binary (machine code)
     • Assembly
