Following is the code for inserting elements in a tree and then retrieving them back using inorder traversal technique elements are getting inserted just fine,but the code doesn't displays the elements of the tree while performing inorder traversal..
Code:
#include<stdio.h>
#include<stdlib.h>
struct node{
int data;
struct node *right;
struct node *left;
}*z,*t,*root=NULL,*x=NULL,*y=NULL;

I am trying to develop a function which prints a binary tree using post-order traversal (left, right, root) but I am experiencing some troubles. The code is compiled but when I run the program it crashes right before printing the post-order traversal.
Below you can find my code and the output from debugging.
Code:
/**
Program which represents a Binary Search Tree and is modified with the following functions:
- smallest() - member function which searches for the smallest element in the tree.
- preorder() - member function which prints the tree nodes using pre-order traversal
- postorder() - member function which prints the tree nodes using post-order traversal (to be completed)

I used a BFS to simulate graph-join structure in a C++ code, and had a binary tree that asks the user e.g. to insert a node in the tree among other options, anyhow, I reached a point where I should pass a set of vertices from the graph to the tree, but how to do so. So I wanted to ask is such a thing possible? i.e. passing vertices from a graph to a tree automatically (no user involvement is needed)?
View 4 Replies View RelatedTraversal of binary search tree. In my header file there is a function setTraversal (public) and private print file. As I understood from teacher's explanation, my setTraversal function should call the recursive print function and print the list depending on selected order (pre,in or post-order). I still cannot get my head around what should be in setTraversal function definition. All resources I read last two days explain each order separately (preorder, inorder, postorder). How can I combine them? Here is my code:
#include "NodeTypeBST.h"

enum TravType {PRE, IN, POST};

I am trying to read/write binary trees to a file for a little project I'm working on for fun. I got frustrated and gave up; now, I am trying again! So I am writing the tree to file (or, rather, to string for now) like so:
string wBinTree(node *p)
{
string str = "";
[Code]....
But now I'm completely lost as to recreating the tree from a string. I thought of perhaps using an array/vector/string of 1's and 0's or trues and falses to keep track of where I was in the tree, but it's really beyond me.
I am having trouble figuring out inorder traversal in this assignment. I was given this function definition in the homework i have to declare it. The problem i am having is how to use function pointer to traverse the list.
void CBSTree<NodeType>::InOrderTraversal(void (*fPtr)(const NodeType&)) const;
void CBSTree<NodeType>::InOrder(const CTreeNode<NodeType> *const nodePtr
,void (*fPtr)(const NodeType&)) const;
//nodePtr is a pointer to a NodeType object (this is a recursive function, initially this points to the root).
//fPtr is a pointer to a non-member function that takes a const reference to a NodeType object as input, and
//returns nothing
I know without the function pointer parameter it will be like this
void InOrder(CTreeNode *nodePtr) {
if(nodePtr != NULL) {
InOrder(nodePtr->left);
cout<<nodePtr->value;
InOrder(nodePtr->right);
}
}
void InOrderTraversal() {
InOrder(root);
}
I just don't know how to traverse inorder with the function definition i am given
I get stuck while I write codes about checking the order of binary tree. Here is what i got so far,
bool BinaryTree<int>::isOrdered(const BinaryTree& root) {
bool order= false;
if(root->left != NULL) {
isOrdered(root->left);
order = root > root-> left;

There can be several errors but what I think the most problematic one is that it only compares the values of parent and child.
Actually I though about creating couple other helper functions to hold values. But I wonder that there can be more efficient way.
I'm new to program breadth first search and for my assignment we have to implement a breadth first search graph and output the order of the traversal. The problem is when I run my program I do not get any output from my traversal. All I get is "Breadth First Search Traversal starts at Vertex 2 and the order is: "

I'm trying to use a priority queue sorting in reverse order to take a vector or 2d array. The problem is that I want to sort by the vector/array cell value but keep the reference to the vector/array index of the value. I don't know quite howto keep them both related so when I pop. I can find the corresponding cell.

For my data-structures class, I am attempting to create a binary search tree template to be used to create an AVL tree. I've written a Generic_Tree template for the BST to inherit from, and before I jump into implementing the AVL tree I'm testing the BST member functions. Everything was compiling fine until I added the BST insert() function. Now, I'm getting the following error message from my linker:
undefined reference to 'BST<void>::insert(int, void*)'
Stemming from the call in main line 16.
my makefile compiles with:
g++ -Wall -g Generic_Tree.cpp BST.cpp barfing.cpp main.cpp

struct NODE {

I'm use to c and havn't used classes or templates before (except for declaring instances of them). The whole syntax is mystifying to me,.
I'm trying to send some binary data, such as an animated gif, via an HTTP response for a simple web server.
I am having issues having the browser close the connection after receipt of the data.
I create the header such as:
"HTTP/1.1 200 OK
Content-Length: <file size>
Content-Type: <file type>
<binary data>"
This is stored in a malloc'ed char *. To add the binary data I'm using fread: fread(request + strlen(request), 1, size, fp)
I then write 'total' bits via connfd:
write(connfd, request, total)
where total = strlen(headerRequest) + size + 3 (for ending
).
The writing seems to be okay however the image doesn't load and the browser still seems to be waiting for data.
If I added "Connection: close" to the header and closed connfd myself the page loads fine. Obviously, for efficiency purposes, I'd rather only close connfd once read() returns 0.
The header creation code is below:
======= Code:
/* Try to get file */
strcat(cwd, file);
if(endsWith (cwd, ".html") || endsWith(cwd, ".htm")) {
strcpy(fileType, "text/html");
binary = 0;
} else if (endsWith(cwd, ".txt")) {
strcpy(fileType, "text/plain");
binary = 0;

It only prints out the root in an infinite loop.
Code: void Btree::printTree(Node* tree)
{
tree=root;
if (tree != NULL)
{
std::cout<<" "<< tree->key;
printTree(tree->left);
printTree(tree->right);
}
}
It has been a while since I built a binary tree from scratch so I decided to do it. Everything works fine but this one function. When I enter a number to search it just keeps running and allowing me to keep enter numbers.
Code:
void tree::search(int key,Node* leaf) {
if (leaf == NULL) {
std::cout<<"The tree is empty

I have a problem with the C code . I created two functions, one that runs through the tree inorder, the other that returns the maximum value in the tree. The problem is when I use in the main the method "max", which goes in a loop and not print anything on the screen . If I remove the call to method "max" it works fine. Here's the code:
Code:
#include<stdio.h>
#include<stdlib.h>
#define bool int
/* A binary tree tNode has data, pointer to left child
and a pointer to right child */

I need to write a program to find the sum of depths of a binary tree, where a depth is by definition the shortest distance between a node and the root. I am required to code this using recursion.
I was thinking of first coding a helper recursion to find the depth for each node. What would be the best way to do that? If I could move from the node to the root, I believe programming this helper recursion would not be very difficult. Is there a way to progress from the node to the root?

I am having trouble with my deleteNode function, using recursion I am trying to delete a node from a binary tree. My tree is displayed as the following...

(c)->[ ,e]

The result did show that it is erased but when I try to add the erase node "t" back into the tree it still exist. I am stumped on what to do when using recursion way of deleting node.
