Linked lists use dynamic memory allocation i.e. they grow and shrink accordingly. It is collection of nodes.
Node has two parts which are as follows −
- Data
- Link
Types of Linked Lists
The types of linked lists in C programming language are as follows −
- Single / Singly linked lists
- Double / Doubly linked lists
- Circular single linked list
- Circular double linked list
Algorithm
Refer an algorithm given below for storing the car information by using the dynamic linked list.
Step 1 − Declare structure variables.
Step 2 − Declare Function definition to display.
Step 3 − Allocate dynamic memory allocation to variable.
Step 4 − Use do while loop to enter the car information.
Step 5 − Call display function goto step 2.
Example
Following is the C program for storing the car information by using the dynamic linked list −
#include<stdio.h> #include<stdlib.h> #include<string.h> struct node{ char model[10],color[10]; int year; struct node *next; }; struct node *temp,*head; void display(struct node *head){ temp=head; while(temp!=NULL){ if(temp->year>2010 && (strcmp("yellow",temp->color)==0)) printf(" %s \t\t %s \t\t %d",temp->model,temp->color,temp->year); temp=temp->next; printf("\n"); } } int main(){ int n; char option,enter; head=(struct node *)malloc(sizeof(struct node)); temp=head; do{ printf("\nenter car model: "); scanf("%s",temp->model); printf("enter car color: "); scanf("%s",temp->color); printf("enter car year: "); scanf("%d",&temp->year); printf("\nDo you want continue Y(es) | N(o) : "); scanf("%c",&enter); scanf("%c",&option); if (option!='N'){ temp->next=(struct node *)malloc(sizeof(struct node)); temp=temp->next; } else { temp->next=NULL; } }while(option!='N'); display(head); return 0; }
Output
When the above program is executed, it produces the following output −
enter car model: I20 enter car color: white enter car year: 2016 Do you want continue Y(es) | N(o) : Y enter car model: verna enter car color: red enter car year: 2018 Do you want continue Y(es) | N(o) : Y enter car model: creta enter car color: Maroon enter car year: 2010 Do you want continue Y(es) | N(o) : N
