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
