Definition​

struct Point:
    int x
    int y

Instantiation​

Point p
p.x = 10
p.y = 20

Nested Structures​

struct Line:
    Point start
    Point end

Line line
line.start.x = 0
line.start.y = 0
line.end.x = 100
line.end.y = 100

Methods​

struct Point:
    int x
    int y

    public def add(self, other: Point) -> Point:
        Point result
        result.x = self.x + other.x
        result.y = self.y + other.y
        return result

Self-Referential​

struct ListNode:
    int value
    ListNode* next

Linked List Example​

struct ListNode:
    int value
    ListNode* next

public def create_list(n: int) -> ListNode*:
    ListNode* head = 0
    ListNode* current = 0
    int i = 0

    while i < n:
        ListNode* node = new ListNode
        node.value = i * 10
        node.next = 0

        if head == 0:
            head = node
        else:
            current.next = node

        current = node
        i += 1

    return head

public def sum_list(head: ListNode*) -> int:
    int total = 0
    ListNode* current = head

    while current != 0:
        total += current.value
        current = current.next

    return total
