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 2.3, 2.4, 2.5 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 with a list comprehension:
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
Libraries: None are needed
// Dynamic int n = 10 * sizeof(int); int *myArray = (int*)malloc(n); if(myArray != NULL) { memset(myArray, 0, n); myArray[0] = 1; myArray[1] = 2; free(myArray); myArray = NULL; }
Libraries: None are needed
// Static int myArray2[10] = { 1, 2, 0}; /* 3..9 := 0 */
C++
Compiler: GCC, MSVC, BCC, Watcom
Libraries: None are needed
// Dynamic const int n = 10; int* myArray = new int[n]; if(myArray != NULL) { myArray[0] = 1; myArray[1] = 2; delete[] myArray; }
Libraries: None are needed
// 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);
