Creating Software

1. IDE (Integrated Development Environment)

   • Example:
     • Python IDLE
     • PyCharm
     • PyScripter
   • TREE:
     • Translator (Compiler and Interpreter)
     • Run Time Environment
     • Editor
     • Error Diagnostics (Debugging Tools)

2. Programming languages

   • Low level Languages
     • 1st Gen: Machine Code (1s & 0s)
       • No translator need
     • 2nd Gen: Assembly Language
       • (Simpler command for each collection of 1s & 0s)
       • Uses an assembler to convert machine code
       • One assembly code = one machine code instuction
   • High Level Languages
     • 3rd Gen: High Level Language (e.g. Python)
       • (Complied or interpreted) One high level instructions, many machine code instructions
       • Easier to use to program for a programmer
     • 4th Gen: Declarative Language
       • Facts and rules stated e.g. SQL / Prolog (A.I Language)
     • Assemblers are not used to translate high level languages
   • The relationship of low level languages and high level languages
     • One to many (For every high level instruction there are many low level instructions)
   • Compiler translates entire source code in one go
