Arrays

In the provided code snippet, we can see how arrays work:

let foo = new string[] { "A", "B", "C" };

let mut bar = i32[4];
bar[0] = 0;
bar[1] = 1;
bar[2] = 2;
bar[3] = 3;

let qux = new i32[4] { 0, 1, 2, 3 };

Array initialization

let foo = new string[] { "A", "B", "C" };

This line declares an array of type string and initializes it with three string elements "A", "B", and "C". In Mew, arrays can be initialized with values directly using the curly braces syntax.

let mut bar = new i32[4];

This line declares an array of type i32, specifying the size of the array as 4. The array is created, but it is initially empty.

Array element assignment

bar[0] = 0;

This line assigns the value 0 to the first element of the integer array bar at index 0. Array indices typically start at 0 in many programming languages.

bar[1] = 1;

Similarly, this line assigns 1 to the second element at index 1, and so on for the subsequent elements.

Array Initialization with Values

let qux = new i32[4] { 0, 1, 2, 3 };

This line declares an array of type i32 and initializes it with four integer values: 0, 1, 2, and 3. This is another way to create and initialize an array with specific values at the time of declaration.
