C Program to find smallest and largest element in single linked list
Write a C Program to find smallest and largest element in single linked list. Here’s simple Program to find smallest and largest element in single linked list in C Programming Language.
What is Linked List ?
Linked list is a linear data structure that contains sequence of elements such that each element links to its next element in the sequence. Each link contains a connection to another link.
Following are the important terms to understand the concept of Linked List.
- Link − Each link of a linked list can store a data called an element.
- Next − Each link of a linked list contains a link to the next link called Next.
Each element in a linked list is called as “Node”. Each node consists of its own data and the address of the next node and forms a chain. Linked Lists are used to create trees and graphs.
Below is the source code for C Program to find smallest and largest element in single linked list which is successfully compiled and run on Windows System to produce desired output as shown below :
SOURCE CODE : :
/* C Program to find smallest and largest element in single linked list */ #include<stdio.h> #include<stdlib.h> struct node { int info; struct node *link; }; struct node *create_list(struct node *start); void display(struct node *start); struct node *addatbeg(struct node *start,int data); struct node *addatend(struct node *start,int data); int largest(struct node *start); int smallest(struct node *start); int main() { struct node *start=NULL; int n; start=create_list(start); display(start); printf("\nLargest element is %d\n",largest(start)); printf("\nSmallest element is %d\n",smallest(start)); return 0; }/*End of main()*/ int largest(struct node *ptr) { int large=ptr->info; while(ptr!=NULL) { if(ptr->info >large) large = ptr->info; ptr=ptr->link; } return large; }/*End of largest()*/ int smallest(struct node *ptr) { int small=ptr->info; while(ptr!=NULL) { if(ptr->info < small) small = ptr->info; ptr=ptr->link; } return small; }/*End of smallest()*/ struct node *create_list(struct node *start) { int i,n,data; printf("Enter the number of nodes : "); scanf("%d",&n); start=NULL; if(n==0) return start; printf("\nEnter the element to be inserted : "); scanf("%d",&data); start=addatbeg(start,data); for(i=2;i<=n;i++) { printf("Enter the element to be inserted : "); scanf("%d",&data); start=addatend(start,data); } return start; }/*End of create_list()*/ void display(struct node *start) { struct node *p; if(start==NULL) { printf("\nList is empty\n"); return; } p=start; printf("\nList is :\n"); while(p!=NULL) { printf("%d ",p->info); p=p->link; } printf("\n\n"); }/*End of display() */ struct node *addatbeg(struct node *start,int data) { struct node *tmp; tmp=(struct node *)malloc(sizeof(struct node)); tmp->info=data; tmp->link=start; start=tmp; return start; }/*End of addatbeg()*/ struct node *addatend(struct node *start,int data) { struct node *p,*tmp; tmp=(struct node *)malloc(sizeof(struct node)); tmp->info=data; p=start; while(p->link!=NULL) p=p->link; p->link=tmp; tmp->link=NULL; return start; }/*End of addatend()*/
OUTPUT : :
/* C Program to find smallest and largest element in single linked list */ ****************** OUTPUT *************** Enter the number of nodes : 8 Enter the element to be inserted : 4 Enter the element to be inserted : 1 Enter the element to be inserted : 8 Enter the element to be inserted : 0 Enter the element to be inserted : 3 Enter the element to be inserted : 9 Enter the element to be inserted : 4 Enter the element to be inserted : 6 List is : 4 1 8 0 3 9 4 6 Largest element is 9 Smallest element is 0
