Variables

Variables are like containers in which values can be inserted or changed.

variable defining:

var name [: type [= value]]

• name: your variable name

NOTE: names should not start with a number, By compiling this code, you will receive an error:

var 6Apple : int

• type: your variable type
• value: your variable value

example :

var myvar : string 
var my_var : int 
var _myvar : float

Variable assignment

Do the following to give a value to the variable :

name = value 

example :

var x : int
x = 14 

You can not assign a value to a variable as opposed to the original type ,this code have error :

var myInt : int
myint = 1.1 # error

Constants

Constant(const) is a type qualifier a keyword applied to a data type that indicates that the data is read only(wikipedia).

for example :

const MyConst = "MyName" # or : let MyConst = "MyName"
print(MyConst) # output : MyName

NOTE: You cannot change the const values. for example (compiler return an error):

const PI = 3.14  # or : let PI = 3.14 
PI = 3.1415  # error
