C Linked List : Exercise-1 with Solution

Write a program in C to create and brandish Singly Linked List.

Pictorial Presentation:

Sample Solution:

C Code:

            #include <stdio.h> #include <stdlib.h>  struct node  {     int num;                        //Data of the node     struct node *nextptr;           //Address of the adjacent node }*stnode;  void createNodeList(int n); // function to create the list void displayList();         // function to display the list  int main() {     int n; 		printf("\n\northward Linked List : To create and brandish Singly Linked List :\n"); 		printf("-------------------------------------------------------------\north"); 		     printf(" Input the number of nodes : ");     scanf("%d", &n);     createNodeList(n);     printf("\due north Data entered in the list : \north");     displayList();     return 0; } void createNodeList(int n) {     struct node *fnNode, *tmp;     int num, i;     stnode = (struct node *)malloc(sizeof(struct node));      if(stnode == NULL) //bank check whether the fnnode is Zippo and if so no memory allocation     {         printf(" Memory can not be allocated.");     }     else     { // reads data for the node through keyboard          printf(" Input data for node 1 : ");         scanf("%d", &num);         stnode->num = num;               stnode->nextptr = Nil; // links the address field to NULL         tmp = stnode; // Creating n nodes and calculation to linked list         for(i=2; i<=n; i++)         {             fnNode = (struct node *)malloc(sizeof(struct node));             if(fnNode == NULL)             {                 printf(" Retention can not be allocated.");                 suspension;             }             else             {                 printf(" Input data for node %d : ", i);                 scanf(" %d", &num);                   fnNode->num = num;      // links the num field of fnNode with num                 fnNode->nextptr = NULL; // links the address field of fnNode with NULL                   tmp->nextptr = fnNode; // links previous node i.east. tmp to the fnNode                 tmp = tmp->nextptr;              }         }     } } void displayList() {     struct node *tmp;     if(stnode == Aught)     {         printf(" Listing is empty.");     }     else     {         tmp = stnode;         while(tmp != NULL)         {             printf(" Data = %d\n", tmp->num);       // prints the data of current node             tmp = tmp->nextptr;                     // advances the position of electric current node         }     } }                      

Sample Output:

            Linked Listing : To create and display Singly Linked List :                                                      -------------------------------------------------------------                                                   Input the number of nodes : 3                                                                                  Input data for node 1 : 5                                                                                      Input data for node 2 : half-dozen                                                                                      Input data for node 3 : seven                                                                                                                                                                                                     Information entered in the list :                                                                                     Data = 5                                                                                                       Data = half-dozen                                                                                                       Data = 7

C Programming: Tips of the Day

C Programming - Different methods to print 'Hello world' without using semicolon in C

How to print any message like "Hullo earth" or how to execute a printf argument in C program without using semicolon.

This article contains some of the methods by using them you can execute whatever printf statement to print any message on the screen without using semicolon (which is a special character in C programming language and it is used to stop the executable statement in C language).

Using if statement

#include<stdio.h> int main() { 	if(printf("Hullo Globe")) 	{;} 	 	render 0; }          

Using loop argument

#include<stdio.h> int main() { 	while(!printf("Howdy World")) 	{;} 	 	return 0; }          

Using switch statement

#include<stdio.h> int master() { 	switch(printf("Hello World")) 	{ 	} 	 	return 0; }          

Using Macro Definition

#include<stdio.h> #define a printf("Hi World")  int main() {     if(a){;} 	return 0; }
