I have made cancer prediction based on symptoms using decision trees but i am not able to run my code ...

I am working on a program that needs to take any infix expression as an input. And the display the expression tree of it on the console as an output. For example the input goes (a+-(c*d) should output:
-
+ *
a b c d
I'm intrested in creating programs of games and such which learns while playing and saving the information for further use. For example a tic tac toe game where the program saves evry game it won or lost and creates a tree of some kind that store the information of the game and save it in a file when the program is being quit. The problem i'm having is how to save a tree in a file efficently.
View 2 Replies View RelatedI have Problems with deleting node in trees!my first problem is I don't understand the algorithm of deleting a node with two child! I write some kind of code that delete a node with two child but I think (maybe I should say I am sure ) that it has runtime or logical errors or something like that!
My second problem is my code doesn't work if my node is root of tree!because I don't know if it is root what should be the parentPtr in my code! I set parentPtr to NULL in this situation but I know it is wrong!
Here is my Code :
#include <iostream>
#include "TreeNode.h"
using namespace std;
template<typename NODETYPE> class Tree {
public:
Tree();
void insertNode(const NODETYPE &);

I've been working on my deletion function for Red and Black trees but can't seem to get it to work. From what I can tell, the remove function, instead of deleting the single value that will my prompt by the user, will delete all the values that are in the red and black tree.
Code:
bool RedBlackTree::remove(int x) {
if(!search(x)){
return false;
} else {
Node* z = new Node(x);
rbremove(z);

I had an assignment that I completed and it was just inserting values into a binary tree and then displaying it. I was wondering what the code would be if I wanted to delete a number in the binary tree, or if I wanted to search for a number. Here is my code for my assignment.
Code:
#include <stdio.h>
#include<stdlib.h>
typedef struct bt_{
int value;
struct bt_ *right;
struct bt_ *left;
[Code] ....
So I have this code that I wrote that pretty much makes a binary search tree with one node per element that holds the data int, one pointer for left, and one pointer for right. My tree is set that if you give it a number it starts as root, then afterwards any number you give it will either be placed left or right if it smaller than the current node or bigger respectively until it hits a pointer that points to NULL.
I was able to get my code to display the numbers in order no matter how bad you inserted the numbers to throw me off. My question now is this, how can I make it count how many levels there are? I'm not sure if this is clear or unclear but I want it to take all the paths and return to me the longest path and that should be how many levels there are.
#include <iostream>
using namespace std;
class binarySearchTree {
private:
class node {

I'm having some trouble with my binary tree for school. It is a data structures class so we are working on learning how to make our own binary trees and encrypt messages. Everything so far is working, except for my delete node function. I'm trying to do it recursively. Parts of my code.
/******** Node *********/
struct node {
char data;
node* right;
node* left;
};
/******** Binary Tree Class *********/

My colleague and I have been given a task to create a list with the employes of a company using binary trees. Each employee/node has to contain the following information:
- Employe name
- Rank
- ID Number
- monthly Salary
We have to write a C program (using Codeblocks) which builds the company tree with the information above and afterwards lists all the employes who have a salary bigger then a number specified by the user.
So far so good. We've had a look on the examples on the internet and after finding one which looked friendly enough we started working on that one to suit our needs. Credits for the original source code to: C Program to Implement Binary Search Tree Traversal - Basic C Programs | C Programming Examples
We've reached the point where we're able to insert the required information but being able to list all the employes who's salary is bigger then the number given by the user seems to be rather difficult to achieve. I'll include the code next. We have left almost the entire pieces of the original code and we are aware that the are still things which are not required for our assignment, which only requires to enter the 4 information above and afterwards display the employes with the before mentioned condition concerning their salary.
Code:
# include <stdio.h>
# include <conio.h>
# include <stdlib.h>
typedef struct BST
