Understanding linked list with struct. Write the following program in your IDE and do the exercise. #include using namespace std; //struct struct node { int x; node *next; }; //initialize head void initNode(node *head, int n){ head->x = n; head->next = NULL; } //add a node to the list at tail void addNode(node *head, int n) { node *newNode = new node; newNode->x = n; newNode->next = NULL; node *cur = head; while(cur) { if(cur->next == NULL) { cur->next = newNode; return; } cur = cur->next; } } 1. Create a print function to print the list content. 2. Create a main to test the program and add the following node values to the linked list: 10, 20, 50. Print the content of the list.
Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).
Understanding linked list with struct. Write the following
#include <iostream>
using namespace std;
//struct
struct node {
int x;
node *next;
};
//initialize head
void initNode(node *head, int n){
head->x = n;
head->next = NULL;
}
//add a node to the list at tail
void addNode(node *head, int n) {
node *newNode = new node;
newNode->x = n;
newNode->next = NULL;
node *cur = head;
while(cur) {
if(cur->next == NULL) {
cur->next = newNode;
return;
}
cur = cur->next;
}
}
1. Create a print function to print the list content.
2. Create a main to test the program and add the following node values to the linked list:
10, 20, 50. Print the content of the list.
