Creating Software

1. IDE

   • Run Time Environment
     • Allows you to quickly run your code, so you can periodically check it works.
   • Editor
     • Colour codes command words (like 'print').
     • Automatically indents code
     • Some auto-complete code as you are writing it.
   • Error Diagnostics
     • Used to debug your code. It locates errors and suggests ways to fix them.
   • Translators (Compiler and Interpreter)
     • Changes it from high level code to low level code.

2. Translators

   • Compilers
     • A Compiler translates all of the original program code (source code) into an executable program (machine code).
   • Interpreter
     • An Interpreter reads each line of code and then converts or executes it directly, without translating the entire program to machine code.

3. Generations of Code

   • 3rd Generation
     • Written in clear English, very easy for people to understand.
       • Used by Python.
   • 2nd Generation
     • Written in very simple words (like ADD). Easier for people to understand than Generation 1.
   • 1st Generation
     • Code written in binary (1s and 0s). Hard for people to understand.
