Variable

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;

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[[ | ]] { [] };


var seq = ["1","2","3" ];

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