Tuples

Tuples in Carbon are immutable ordered collections of values. They are similar to arrays but have a fixed size and can contain elements of different data types. Tuples are often used to group related data together.

Creating Tuples

Tuples are created using parentheses (), with elements separated by commas. The data type of each element is inferred from its value.

Code snippet

var myTuple: (int, string, bool) = (10, "Hello", true);

Accessing Elements

Elements in a tuple are accessed using their index, starting from 0.

Code snippet

var firstElement: int = myTuple.0;
var secondElement: string = myTuple.1;
var thirdElement: bool = myTuple.2;

Tuple Destructuring

Tuple destructuring allows you to extract elements of a tuple into individual variables.

Code snippet

var (a, b, c) = myTuple;

Tuple Methods

Tuples have several methods:

count(): Returns the number of elements in the tuple.
dropFirst(): Returns a new tuple without the first element.
dropLast(): Returns a new tuple without the last element.
isEmpty(): Returns true if the tuple is empty, false otherwise.
startIndex(): Returns the starting index of the tuple.
endIndex(): Returns the ending index of the tuple.

Example

Code snippet

var person: (string, int, bool) = ("Alice", 30, true);

print("Name: \(person.0)");
print("Age: \(person.1)");
print("Is employed: \(person.2)");

var (name, age, isEmployed) = person;
print("Name: \(name)");
print("Age: \(age)");
print("Is employed: \(isEmployed)");
