Programming languages

1. IDE

   • Features of an IDE
     • Editor
       • Auto colour codes key command words
     • Run-Time Environment
       • When you want to edit and output your code, it is done through this.
     • Translators
       • Translates High level programming languages to low level programming languages or vise versa.
       • Interpreter
         • Translates code line by line
       • Compiler
         • Translates all the code at once
       • Assembly Languages
         • Little man computer
         • Mnemonics are shortened down command words like load is LDA in assembly code. They are able to be understood by low level programming languages
     • Error Diagnostics
       • Checks for errors when you code and compile
     • T.R.E.E
   • IDE stands for Integrated development environment
   • Examples include IDLE Python and Pycharm
   • Evaluation : IDLE
     • Colourful editor
       • Makes it easier to code as you can spot if you have made a simple error in your program
     • Got a run-time environment
       • Easier to un you programs and files without having to compile them to an exacutable
     • No linenumber
       • Means if there is an error it will be harder to spot as you have to count all the lines to get the line number you want
     • Lacks error diagnostics while you write the code
       • Makes it harder to code as you have to run the code to see if there are any errors
     • Doesn't have a debugger
       • Have to manually change any errors you have made whule writing code
     • Translates to low level programming languages
       • Means it can run better and the computer can understand it

2. High Level Programming Languages

   • Designed to be understood by humans
   • Examples include Python and Java

3. Low Level Programming languages

   • Designed to be understood by the compuer
   • Examples include java and C++
   • Also known as machine code/assembly language
