Declaring arrays

Last updated 3 months ago

Declaring one-dimensional arrays

A one dimensional fixed array is created either via an array literal or via appending [] to the type of the variable with the size or *(for an infinite array) between the brackets. If no variable type is given, the type array is infered on first use and the variable will be an infinite array


with console from std:io
var hello = {"Hello","world"} //type of the array is infered here, fooBar is now a string[2]
console->out:hello [0] + hello [1] //Output: Hello world
var fooBar
fooBar[0] = 10 //type of the array is infered here, fooBar is now an int[*]
fooBar[1] = 20
var int[10] fib = {1,1,2,3,5,8,13,21,34,55}
var barFoo
barFoo[0] = null //type of the array is infered here, barFoo is now an object[*]
let string[*] text = console->in()->split(" ")

Declaring multi-dimensional arrays

The syntax of creating multi-dimensional arrays is similar to that of creating one-dimensional arrays. But instead of a single size, you put the size of each dimension between the brackets seperated by a . .


var int[3.3] matrix = {{1,0,0},{0,1,0},{0,0,1}}
var names = {{"John", "Greg"}, {"Anna", "Susan"}} //type of the array is infered here, names is now a string[2.2]
let int[*] a = {{3,7,3,0},{0,2,-1,1},{5,4,3,2},{6,6,4,-1}}

Arrays of nullable types

Making an array nullable is done in the same way as making a variable nullable: you put a ? in front of the datatype or let the interpreter infer the array type.


var int?[2.2.2] 3dArray = {{{1,2},{3,null}},{{null,6},{7,8}}}
var strings = {null, "Hello","World"} //type of the array is infered here, strings is now a string?[3]
