Programming Languages

1. IDE

   • Features of an IDE
     • Editor
       • Allows you to write and edit code
         • Makes it easier to write code by:
           • Auto indentation
           • Auto-colour Coding
           • Line numbering
           • Auto-correct
           • Auto-complete
           • You just wasted your time reading this, not to mention effort (that is unless you just zoomed out. NAAH that won't work here ;))...
     • Translator
       • Translates High level languages into Machine code before a Computer is able to Execute instructions.
         • Compiler
           • Translates all the code and then alerts the user if there is an error found
         • Interpreter
           • Translates code one line at a time, it stops when it reaches an error
     • Error Diagnostics
       • They help to Find and fix Errors in a program. It tells you the Location of the Error and often Suggest ways to Fix It
     • Run Time Environment
       • Allows code to Run and be Tested in the IDE. It helps to Identify Logic Errors.
   • Integrated Developer Environment
   • Examples: IDLE, Pycharm

2. High Level Programming Languages

   • Designed to be understood by humans
   • Java, C#

3. Low Level Programming Languages

   • Designed to be understood by Computers
   • Assembly Language
     • It uses mnemonics
       • These are shortened instructions/command words.
       • For example
         • STA - Store
         • LDA - Load
         • ADD - Addition
         • SUB - Subtraction
         • DAT - Data
         • HLT - Halt program
