Q. Write  down a   programme  in  C  to  create  a  single  linked  list also  write the functions to do the following operations

(i)  To insert a new node at the end

(ii) To delete the first node                                                                                                                                     

Ans:

//Create a single list

struct node

{

int data;

struct node *link

}

struct node *p,*q;

//Inserting a node at the end(append)

append(struct node **q,int num)

{

struct node *temp; temp=*q; if(*q==NULL)

{

*q=malloc(sizeof(struct node *));

temp=*q;

}

else

{

while(temp        link!=NULL)

temp=temp   link;

temp   link = malloc(sizeof(struct node *));

temp=temp   link;

}

Temp   data=num;

temp     link=NULL;

}

//Delete the first node delete(struct node *q,int num)

{

struct node *temp;

temp=*q;

*q=temp   link;

free(temp);

}
