C :: Guessing Game Program - Binary Search

Apr 5, 2014

I'm playing with a guessing game program as a personal exercise, but I'm missing a vital piece - the binary search-style code.

"Have the program initially guess 50, and have it ask the user whether the guess is high, low, or correct. If, say, the guess is low, have the next guess be halfway between 50 and 100, that is, 75. If that guess is high, let the next guess be halfway between 75 and 50, and so on."

(We're assuming that the user won't cheat.) I need the average, essentially. As in, (50 + 75) / 2 = 63.. but when I use this method of "guess = (high+low)/2, it just keeps giving me 50. I can't remember what operators I should use to increment the program's response based on the user's input. It's literally a binary search, that needs to go where those TODOs are. If low was chosen, it would have to start by being at least 51, to 100, so I'd have to set that, then find the average.

Code:
#include <stdio.h> Code: #include <ctype.h>
int main(int argc, const char * argv[]) {
int low;
int high;
int guess;
int response;
int toupper ( int );

C/C++ :: Binary Search Tree Program - Segmentation Fault Error

Mar 21, 2014

I'm writing a binary search tree program and I got it to compile but as soon as I input something it returns a "segmentation fault error" . I suspect the issue with the code is withing my `add` function.

template<typename T>
void BinarySearchTree<T>::add(T value) {
if (m_root == nullptr) {
Node<T>* node = new Node<T>;
node->setValue(value);
m_root = node;

C++ :: Binary Search Or Linear Search For 3D Array

Oct 7, 2014

inputting a search array. I tried putting a binary search but I can't get it to work. everything else works up until I put the value I am searching for in the array, then it just crashes.

How it suppose to work: input 2 coordinates with a value each then it calculates the distance between them then it suppose to let user search the coordinates for a value and state if found which coordinate it is at.

#include "stdafx.h"
#include <iostream>
#include <iomanip> //for setprecision

C++ :: Search Binary Tree

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

C++ :: Binary Search Tree Printing

Apr 19, 2014

I am not sure how to use the parameters ostream and enum type in a print function.

enum TraversalOrderType {preorder, inorder, postorder};

C++ :: Binary Search Tree Remove?

C++ :: Binary Search Delete Function

Nov 26, 2013

I am having an issue when i try to delete a node with 2 children it either doesn't delete anything, or wigs out in various manners deleting the wrong node or replacing a node with a various memory location. As follows, here is the delete function:

void BST::dele(){
bool found = false;//initialize a bool type to "find" the element to be deleted
if(root == NULL) return;//well if the tree's empty, nothing to be found right?
current = root;//set the current to the root to traverse the tree in search of the element
node* parent;//create a parent node for use once the node has been deleted
while(current != NULL){//traverse the tree

C++ ::  Traversal In Binary Search Tree

Apr 29, 2013

Traversal 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"
#include <iostream>
enum TravType {PRE, IN, POST};
template<class T>
class BST

C/C++ :: Implementing A Binary Search Tree?

Mar 20, 2014

I'm working on a programming homework that asks us to implement all the functions of a Binary Search Tree using templated classes. I'm almost done with it but I'm sort of stuck with the last part which is the `search` function. For this part the homework asks for the following requirements

Quote

Node<T>* search(T value, Node<T>* subtree)

if the current node's value is the one we're search for, return a pointer to itif the current node's left and right subtree's are empty (both m_left and m_right are looking at nullptr) then return the nullptr to indicate we didn't find the valueif the value is less than the current node's value, return the search of the left subtreeif the value is greater than or equal to the current node's value, return the search of the right subtreeMake sure to only traverse a subtree if it's not null

C/C++ :: Creating A Binary Search Loop?

Oct 13, 2014

I am creating a binary search program that lets the user input up to 10 integers and then the program displays the array and sorts it. When the user is prompted to select an integer, if the integer is in the array, the program responds with the array subscript part. I can get the loop to work once and maximum twice, but then it wont search for the array or say value not found even though the number in in the array. I tried making the values NULL but that only lets me go through it one more time.

Here is my code:

#include <iostream>
using namespace std;
//Functions
void printArray(int);
void selection(int);
int binarySearch(int,int,int);

C++ :: Lexing File Into Binary Search Tree

May 22, 2013

Standard example. I have a large text file and I wish to lex it into words. I tell the program that all words are delimited by ' ' ';' ':' and ''.

When I run the program it seems to be outputting the occurances of the letters and not the words. Im gobsmacked, I dont know what the hell is going on. Heres the function that lexes letters and not words. I want words dammit words!!

First youll see I define root node and point it to null; This forms the base of the BST. Then keep munching one character at a time until EOF reached. If the character is not a delimiter, assign it to "word" string, character by character. If it is a delimiter, take the so-far-constructed "word" and chuck it in the BST, then clear the word string through .clear().

Repeat until done. But its not working.

Code:

struct masternode* lexical_scanner(ifstream* inputfile) {
string word;
char c;
struct masternode* root = NULL;
while (c!=EOF){

[Code] .....

All the other functions in the source file are just fine, I've tested them in other apps and they are purpose built.

C :: Search And Delete Function For Binary Trees

Apr 1, 2014

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;

C :: Binary Search Tree In Linked List

Feb 25, 2014

Code:

#include <stdio.h>
#include <conio.h>
#include <stdlib.h>
struct bst {
int val, level;
struct bst *left, *right, *parent;

[Code]....

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.

C++ :: Binary Search Tree - Undeclared Identifier

Mar 8, 2013

I'm trying to create a template binary search tree and I'm getting all these vague errors that I have no clue how to solve. I've narrowed it down to my findMax and findMin functions but i can't figure it out any further than that.

class BinarySearchTree{

struct BinaryNode{
T data;
BinaryNode *left;
BinaryNode *right;

C++ :: BST Iterative Insert For Binary Search Tree

May 13, 2014

I'm writing the function as described in the title but it isn't quite working. It works as long as the value passed is less than the parent (going left) but when the value should be placed to the right, it doesn't actually insert the node.

template <typename T>
void BST<T>::insertHelper(BST<T>::BinNodePtr &subRoot, const T& item) {
BinNode *newNode;
BinNode *parent;
BinNode *child;

[Code] ....

FYI, I've commented out setting the children of the new leaf to NULL because the constructor already does that.

C++ ::  Binary Search Trees - Counting How Many Levels Are There

Jan 29, 2013

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 {

C++ :: Number Guessing Game Binary Search

Sep 3, 2013

Basically i need to make a number guessing game where user thinks of a numbver from 1 - 100 and the machine will try to guess it in the least number of times. Once it guesses the number it will also say how many tries it took to guess.

My code so far is

#include<iostream>
using namespace std;
const int MAX = 100;
int main() {
char ch;

cout << "Think of an integer number between 0 and " << MAX<<endl;
cout << "Write it down on a piece of paper then hit a key to continue"<<endl<<endl;
cin.get(ch);
