Creating an Array
You are encouraged to solve this task according to the task description, using any language you may know.
You are encouraged to solve this task according to the task description, using any language you may know.
In this task, the goal is to create an array.
mIRC
Interpeter: mIRC Script Editor Libraries: mArray Snippet
alias creatmearray { .echo -a $array_create(MyArray, 5, 10) }
Visual Basic 2005.Net
Dim myArray as new ArrayList Dim myArray2 as new ArrayList = { "Item1", "Item2" }
Quick Basic
Interpeter: QB 4.5 or PB 7.1 Libraries: None are needed
' $DYNAMIC DIM SHARED myArray(-10 TO 10, 10 TO 30) AS STRING REDIM SHARED myArray(20, 20) AS STRING myArray(1,1) = "Item1" myArray(1,2) = "Item2"
Javascript
var myArray = new Array(); var myArray2 = new Array("Item1","Item2"); var myArray3 = ["Item1", "Item2"];
3DS Max 8 - MaxScript
myArray = #() myArray2 = #("Item1", "Item2")
Python
Interpeter: Python Libraries: None are needed
Array=[ [0,0,0,0,0,0], [1,1,1,1,1,1], [2,2,2,2,2,2], [3,3,3,3,3,3] ] #You would call the array by this code. This will call the 3rd 1 on the second list Array[1][3]}
Alternatively you can create it programmatically. e.g.
Array = [ [i]*6 for i in range(4) ]
Create an empty array:
Array = []
Perl
Interpeter: Perl Libraries: None are needed
@Array=( [0,0,0,0,0,0], [1,1,1,1,1,1], [2,2,2,2,2,2], [3,3,3,3,3,3] ); #You would call the array by this code. This will call the 3rd 1 on the second list print $Array[1][3];
# Alternative: my @array_using_qw = qw/coffee sugar cream/;
PHP
$array = array( array(0, 0, 0, 0, 0, 0), array(1, 1, 1, 1, 1, 1), array(2, 2, 2, 2, 2, 2), array(3, 3, 3, 3, 3, 3) ); #You would call the array by this code. This will call the 3rd 1 on the second list echo $array[1][3];
Ruby
array = [ [0, 0, 0, 0, 0, 0], [1, 1, 1, 1, 1, 1], [2, 2, 2, 2, 2, 2], [3, 3, 3, 3, 3, 3] ] # You would call the array by this code. This will call the 3rd 1 on the second list array[1][3]
# You can also create a sequential array from a range using the 'splat' operator: array = [*0..3] #=> [0,1,2,3] # This lets us create the above programmatically: array = [*0..3].map {|i| [i] * 6} #=> [[0, 0, 0, 0, 0, 0], [1, 1, 1, 1, 1, 1], [2, 2, 2, 2, 2, 2], [3, 3, 3, 3, 3, 3]]
Ada
Compiler: GCC 4.1.2
type Arr is array (Positive range <>) of Integer; Uninitialized : Arr (1 .. 10); Initialized_1 : Arr (1 .. 20) := (others => 1); Initialized_2 : Arr := (1 .. 30 => 2); Const : constant Arr := (1 .. 10 => 1, 11 .. 20 => 2, 21 | 22 => 3);
OCaml
let nbItems = 5 and initialValue = 0 in make_vect nbItems initialValue
Java
For example for an array of 10 int values: int[] intArray = new int[10];
C
Compiler: GCC, MSVC, BCC, Watcom
// Dynamic int n = 10 * sizeof(int); int *myArray = (int*)malloc(n); memset(myArray, 0, n); myArray[0] = 1; myArray[1] = 2;
// Static int myArray2[10] = { 1, 2, 0}; /* 3..9 := 0 */
C++
Compiler: GCC, MSVC, BCC, Watcom
// Dynamic const int n = 10; int* myArray = new int[n]; if(myArray != NULL) { myArray[0] = 1; myArray[1] = 2; delete[] myArray; }
// Static int myArray2[10] = { 1, 2, 0}; /* 3..9 := 0 */
Libraries: STL
// STL std::vector<int> myArray3(10); myArray3.push_back(1); myArray3.push_back(2);
Libraries: Qt
// Qt QVector<int> myArray4(10); myArray4.push_back(1); myArray4.push_back(2);
Libraries: MFC
// MFC CArray<int,int> myArray5(10); myArray5.Add(1); myArray5.Add(2);
