Programming

1. Datatypes

   • String
     • A sequence of characters often stored as a variable in a computer program
   • Boolean
     • True or false
   • Character
     • A single letter, digit or punctuation mark
   • Real
     • Not whole number
   • Integer
     • A whole number

2. Control flow

   • Selection
     • A decision within a computer program when the program decides to move on based on the results of an event
   • Iteration
     • In computer programming, this is a single pass through a set of instructions
   • Sequence
     • In computer programming, this is a set of actions that follow on one from another

3. Translators

   • Assembler
     • An assembler translates assembly language into machine code - Low level language
   • Compiler
     • A compiler translates the whole program into machine code before the program is run - High level language
   • Interpreter
     • An interpreter translates code into machine code, instruction by instruction - High level language

4. IDE (Integrated Development Environment)

   • Editor
     • a text edit area that allows developers to write, edit and save a document of code. It has features that assist with the writing and editing of code
   • Translator
     • This compiles or interprets the code
   • De-bugger
     • This is a program within the IDE that is used to detect errors. If the debugger detects errors, it may suggest what the type of error is and what line it is on
   • Run-time environment
     • This means that you can execute the program one step at a time showing you what the code would look like
   • Explorer
     • Opening different files and folders
   • Auto-completion
     • This is designed to save time while writing code

5. Errors

   • Syntax
     • mistakes in the way that the code is written
   • Logic
     • mistake in a program's source code that results in incorrect or unexpected behavior

6. Arrays

   • An array is a list
   • Each item in an array has an index
   • EX. array[0] is the first item
