Variable

  1. Variable
    1. Copy the code to the editor:
               
      

var a = 10; var b = 20.5; var c = a + b;

    1. Format the code (press <Ctrl+F5>).
    • EXPECTED RESULT: The code should be formatted

var a = 10; var b = 20.5; var c = a + b;

  1. Data Types
    1. Copy the code to the editor:
               
      

var i = 3; var num = 3.0;

var b = true;

var c = "2".charAt(0);


var byte:Byte = 1; var short:Short = 2; var long:Long = 3; var float:Float = 5.0; var double:Double = 10.0;


var date = 3h;

var str = "Hello!";

class A{}

var a = A{};

var void = function():Void{};

var f = function(a:Number, b:String):Boolean { true }; var seqf = function(a:A[[ | ]], b:String[[ | ]]):Boolean[[ | ]] { [] };
