Question 2Which structure definition represents a singly linked list structure?1 pointstruct node { struct node next; uint32_t data;};union node { uint32_t data1; uint32_t data2;};struct node { uint32_t data; struct node * next; };struct * node { Struct node data; Struct node * ptr;};struct node { struct node * prev; struct node * next; uint32_t data;};

What is the structure of the Doubly Linked List in below given syntax ?Optionsclass Node {public:  int data;  Node* next;};class Node {public:  int data;  Node* next;  Node* front;};struct link {  int info;  struct link* next;};struct Node {  int data;   struct Node* next;  struct Node* prev;};

What is a Doubly Linked List in data structures?a)A list of elements with two types of data.b)A list with elements arranged in ascending order.c)A list where each node points to both the previous and next nodes.d)A list where each node points to the next node only.

StructuresThe following C declarationsstruct node { int i; float j;};struct node *s[10] ;define s to beOptionsAn array, each element of which is a pointer to a structure of type node.A structure of 2 fields, each field being a pointer to an array of 10 elements.A structure of 3 fields: an integer, a float, and an array of 10 elements.An array, each element of which is a structure of type node.

What additional pointer does a node in a doubly linked list have compared to a node in a singly linked list?a.A pointer to the next nodeb.A pointer to the head nodec.A pointer to the tail noded.A pointer to the middle nodee.A pointer to the previous node

structures in CA structure is a user-defined data type available in C that allows to combining data items of different kinds. Structures are used to represent a record.Defining a structure: To define a structure, you must use the struct statement. The struct statement defines a new data type, with more than one member. The format of the struct statement is as follows:   struct [structure name]   {       member definition;       member definition;       ...       member definition;   };unionA union is a special data type available in C that allows storing different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple purposes.Defining a Union: To define a union, you must use the union statement in the same way as you did while defining a structure. The union statement defines a new data type with more than one member for your program. The format of the union statement is as follows:    union [union name]    {       member definition;       member definition;       ...       member definition;    };Similarities between Structure and UnionBoth are user-defined data types used to store data of different types as a single unit.Their members can be objects of any type, including other structures and unions or arrays. A member can also consist of a bit field.Both structures and unions support only assignment = and sizeof operators. The two structures or unions in the assignment must have the same members and member types.A structure or a union can be passed by value to functions and returned by value by functions. The argument must have the same type as the function parameter. A structure or union is passed by value just like a scalar variable as a corresponding parameter.‘.’ operator is used for accessing members.Consider the following C declaration. struct {     short s[5];    union {          float y;          long z;     }u; } t;Assume that objects of the type short, float and long occupy 2 bytes, 4 bytes and 8 bytes, respectively.
