C++ :: Linked List - Recursion For Search Function
Mar 19, 2013
I have a linkedList search function given and I am having a little trouble getting it to work. I've made a few attempts with no success. Given normal search code:
template <class Type>
bool orderedLinkedList<Type>::search(const Type& searchItem) const {
bool found = false;
nodeType<Type> *current; //pointer to traverse the list
current = first; //start the search at the first node
[Code] .....
My attempt to make it a recursive search:
template <class Type>
bool orderedLinkedList<Type>::search(const Type& searchItem) const {
//bool found = false;
nodeType<Type> *current; //pointer to traverse the list
current = first; //start the search at the first node
I'm have troubles with this program that requires me to make a search through a Linked List and find a specified value. It also needs to be a template function. I've completed the rest of the program fine and everything runs ok except for the search function. Code below:
The program I have below. If you copy and paste it it should work. However, When I uncomment my search function I get lots of errors and I think it has to do with incorrect syntax of it being a template. Need to do this search function:
Linked.h header file
Code: #ifndef LINKED_H #define LINKED_H #include<iostream> template <class T> class Linked { private: // Declare a structure for the list
It fills the singly-linked list with 0 through 9 and calls a function to prompt the user to search for a number. I don't see any glaring errors, I was just wondering what could be done to simplify it or if there's anything I missed.
I have a linked list I made and am practicing a simple recursion function sum() which returns the sum of all numbers in each node of the list. Here is my sum() function:
int sum(ListNode *ptr){ if (ptr->next) return (ptr->num + sum(ptr->next)); else return(0); }
where the initial arg passed through the ListNode * parameter is my head node (with null value). The output is fine until that point, then the program locks up and I get the "...has stopped working" error.
I have been asked to write three functions for a Liked List that can add remove and reverse the elements of the Linked List. Now, I have done the add function and It is displaying the elements properly using recursion function. But My removal function is not working and I tried all the possible logic I can think of, I dont know, where did I make mistakes.
This is My class for the Linked List
#ifndef __Linked_Lists_Recursive_function_Implementation___NumberList__ #define __Linked_Lists_Recursive_function_Implementation___NumberList__ #include <iostream> using namespace std;
I was trying to reverse a linklist in reverse direction using the recursion. I was able to reverse n - 1 element but it is not printing the first one. Below is my code.
Code:
typedef struct linklist { int data; linklist *next; };
void add(int data,linklist **node) {
[code]....
This is happening since recursion is starting from second node, which is due to reason not printing the first one when recursion print values from stack once
node != NULL
Condition is met.
Currently I am using below statement for printing the first element;
reverse_recur(node); printf(" Print In Reverse Order %d ",node->data);
What is "if(prev)"? Wouldn't "prev" always have the same value? Secondly, if tmp is NULL (which will be the case when the loop if(ptr->val == val) finds a match the first time it is run), is *prev assigned a NULL?
I have a linklist program I've written that seems to work just fine at least, it outputs the right information. However when it comes to the end and says press any key to continue, it crashes when I press a key says debug assertion error rather than just exiting. I haven't gone back and put in comments yet, I know I need to get used to commenting as I go />/>
#ifndef LIST_H #define LIST_H #include <iostream> #include <cstdlib> using namespace std; template <class T> class LinkList {
[Code] ....
Another bit of information. It was working without crashing when I only had the intlist functions called. When I added the doublelist is when I began getting the error however now if I remove the doubelist and go back to just having the intlist calls it still gives the error.
I've got this program that I'm working on. Most of the code is from a video tutorial, but I was editing it to be able to search for an element by name. That's working fine, but suddenly the part of the program that prints out all the elements starts in an infinite loop after I input two elements, and search for one.
The code above is supposed to be a binary search tree. The main outcome for this program is to display the tree in C each time the user inserts or deletes a value.
Since I am a newbie in C programming, I first tried creating a code that would simply display the values in the tree after a user inserts and deletes, before I proceed to displaying the exact tree.
But when I run it the following output shows:
And when I try to insert another value, It won't display anything and won't respond to any keys pressed.
I am getting an Unhandled exception at 0x00CB569E in AusitnHorton_Chapter17_7.exe: 0xC0000005: Access violation reading location 0xCCCCCCCC.
And, It puts a little yellow arrow at this line:
cout << nodepointer->value << " ";//print current node
when I try to run this program.
//Program:Make a ListNode and simple linked list class. Test the linked list class by adding varous numbers to the list and then test for membership. Then include a search function that returns the position of x on the list, if not found return -1.
Any example of a graph search algorithm that uses a recursion and linked list based stacks to determine a route from a single point on a graph to another single point on a graph?
I am having to write a program that takes 2 sorted linked lists (x and y) and merge those to sorted into a third one (z). This has to be done via recursion. I think I am close but there is a logic error.
Here are the errors: no matches converting function `concat' to type `class Dlist (*)(class List<int>, class List<int>)' error candidates are: template<class T> Dlist concat(Dlist, Dlist)
no matching function for call to `concat(Dlist&, Dlist&)'
I can't understand what the compiler is trying to tell me.
I'm trying to create a function that allows insertion anywhere in a linked list...here is what I have so far but am a bit confused on where to go from here
I'm writing a linked list program for class that has a simple text based menu and I believe I am nearly done, it just wont recognize my "count" function as a function and I don't know why. The error comes up at line 70.
It is suppose to insert items in Linked List in sorted ascending order and no duplicates are allowed.The code complies but it creates duplicates out of order.
I am trying to write a function to return the first element of a link list queue. I am not real sure how to implement this. I have include a copy of the struct for my Node & queue.
