Programming

1. Control flow

   • Selection
     • is when you making a decision such as if or else
   • Sequence
     • is the order of the program
   • Iteration
     • is when the program has been looped or repeated

2. DataTypes

   • String
     • collection of data such as hello
   • Integer
     • A whole number example 12

   • Assembler
     • Assembler is a low level

   • Compiler
     • translates high level code into low level all at once
     • Saves it as a exe file so it can run in other computer without the user to access the code.
     • you use it when you have finished your code.
     • if there is a mistake the whole program wont run.
   • Interpreter
     • translates high level language into low level line by line.
     • you use this when you writing a code
     • because it goes line by line it tell you if there is a mistake and where it is.

4. IDE( integrated development environment)

   • Ediitor
     • Syntax check
     • colour coding
     • autocomplete
     • autoindent
     • Is a feature where you write the code.
   • De-bugger
   • Explorer
     • shows you all the files so you can access them
   • Translater
     • Translates high level code into low level so the computer can understand.
   • Run-time environment
     • lets you run the program.

5. Arrays

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