This tutorial demonstrate the implementation of singly linked list.

Description:

In this example you will see how to create a node and insert data record in singly link list. 

Code:

# include <stdio.h>
# include <stdlib.h>
struct node
{
int data;
struct node *link;
};
struct node *insert(struct node *p , int num)
{
struct node *temp;
 if(p==NULL)
	{
	p=(struct node *)malloc(sizeof(struct node));

	if(p==NULL)
	{
	printf("Error Occurred\n");
	exit(0);
	}
	         p-> data = num;
		 p-> link = NULL;
	 }
	 else
	 {
		temp = p;
	while (temp-> link != NULL)
	temp = temp-> link;
	temp-> link = (struct node *)malloc(sizeof(struct node));
	if(temp -> link == NULL)
	{
		printf("Error Occurred\n");
		exit(0);
	}
	temp = temp-> link;
	temp-> data = num;
	temp-> link = NULL;
	}
	return (p);
}
void printlist ( struct node *p  )
{
	printf("The data values of your list are\n");
	while (p!= NULL)
	{
	printf("%d\t",p-> data);
	p = p-> link;
	}
}
void main()
{
	int n;
	int x;
	struct node *start = NULL ;
	printf("Enter number of nodes you want to create \n");
	scanf("%d",&n);
	while ( n-- > 0 )
	{
	printf( "Enter data values for each node\n");
	scanf("%d",&x);
	start = insert ( start , x );
	}
	printf("The created single link list is\n");
	printlist ( start );
}
