![]() First is a variable, data, which will hold the integer value inside it. ![]() The above code represents the structure for our linked list which contains two things. And then we’ll actually create a linked list by assigning memory to use using the malloc() function. The structure is a data type inside which we can define variables with different data types (e.g., int, char, pointer, etc.).įor creating a linked list, we’ll define the structure of our linked list (using the struct data type), which will represent what a single node in a linked list will look like. In C programming, we use structures to create a linked list. That’s why we call it a doubly linked list. In a DLL, we have two pointers: One pointer will point to the next node, and another will point to the previous node. In a SLL, we have a single pointer that’ll point to the next node and, therefore, it is called a singly linked list. ![]() There are two types of linked lists: singly linked lists (SLL) and doubly linked lists (DLL). A linked list basically can have n nodes, and each node is connected to its next node with the help of a pointer. A data structure is nothing but how we organize and store the data in memory.Ī linked list consists of various nodes, and each node contains two things: One is the data, and the other is the pointer, which will point to the next node.
