Singly linked list

Q. Write a C program that create a singly linked list.


Ans.


/*c program for creating singly linked list*/
#include<stdio.h>
#include<conio.h>
struct single_link_list
{
  int age;
  struct single_link_list *next;
};
typedef struct single_link_list node;
node *makenode(int );
int main()
{
  int ag;
  node *start,*last,*nn;   //nn=new node
  start=NULL;
  while(1)
  {
     printf("Enter your age : ");
     scanf("%d",&ag);
     if(ag==0)
        break;
     nn=makenode(ag);
     if(start==NULL)
     {
        start = nn;
        last = nn;
     }   
     else
     {
        last->next = nn;
        last = nn;
     }
  }
  printf("\n\t****Single linked list****\n\n");
  for(; start!=NULL; start=start->next)
     printf("%d\t",start->age);
  getch();
  return 0;
}


/*creation of node*/


node *makenode(int tmp)
{
  node *nn;
  nn = (node *)malloc(sizeof(node));
  nn->age = tmp;
  nn->next = NULL;
  return nn;
}
