    Hi
    This prg is for creating a link list .But Iam not able to understand what will last line do q->link=tmp;

    Code:
    int create(int data)
    {
    	struct node *q,*tmp;
    	
    	tmp=malloc(sizeof(struct node));
    	tmp->info=data;
    	tmp->link=NULL;
    	
    	if(start==NULL)
    		start=tmp;
    	else
    	{	
    		q=start;
    		while(q->link!=NULL)
    		{
    			q=q->link;
    		}
    		
    			[B]q->link=tmp;[/B] // why this is required
    	}
    }

    It will assign the last node ( the one which is being created ) at the end of the q

    in temp you are taking the data to be inserted in the linked list .

    so you are attaching that node as the next node of q here
