C++ :: BST Node And Count Function Don't Work?
Dec 2, 2013
I have to do a BST project for school and I am almost there. Here is the code:
BINARY_SEARCH_TREE.cpp
#include "stdafx.h"
#include "genBST.h"
#include <iostream>
using namespace std;
[Code].....
When I run the program, it compiles correctly but does not give any output. I'm not sure what else to do. I've tried changing up the code in nodeCount(), leafCount(), NodeCount(), and LeafCount(). I've tried adding a count variable to both nodeCount() and leafCount() but that didn't work. If I fiddle with the functions, I get a whole mess of errors. Currently, the code is stable but just won't output what I want it to.

4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

i need a function that will work for both dynamic and static implementations of a function to get the transverse of a matrix. so far, i have this
Code:
matrix transpose(matrix m)
{
int row, col;
row = m.com_dim;
col= m.row_dim;
}
[code]....
this works well with my static implementation, but when i try it in dynamic it gives me errors. the function has to be the same for both dynamic and static implementation

I have this:
string input;
unsigned short choice;
...
istringstream valid(input);
...
if(!(valid >> choice))
{
//some error
}
Ok. My code is almost 1000 lines, and I have splited some functions in headers. But the same function doesn't work:
template <typename T> bool valid_input(const string& input, T var)
{
istringstream valid(input);
return (valid >> var);
}
You can check it here: [URL] The output is correct, but in my machine with C++11, MinGW 4.8 (64 bit in a 64bit-Windows8), the output is incorrect. Why?
If you want more specific info, the problem is that I use input, I think. I use std::getline(std::cin, some_string).

I am working on C# Project [Windows Form Application], to update treeview nodes from excelsheet [xls] Cell [row i, Column 3] Values, while on selecting treenode, it should update corresponding Column 4 Value [row i, Column 4]. For me, Treenode are populated successfully, but on selecting the treenode, it always display first Element of treenode [Not selected one].
Populated Treenode from Excel as: [ Update Child Nodes from Column 3 elements [Column 2 Contain Parent node name and Column 3 have Child Node name], if Column 2 Value is same as Parent node name [My Module], update the child nodeunder same Parent node.]
for (int i = 0; i < worksheet.UsedRange.Rows.Count; i++) {
string mynode = ((Excel.Range)worksheet.Cells[i + 1, 3]).Value2.ToString();
string mynode2 = ((Excel.Range)worksheet.Cells[i + 1, 2]).Value2.ToString();
[Code] ....
On selecting the Child Node, it always give 1st Parent node. Instead of Selected Node.
for (int i = 0; i < worksheet.UsedRange.Rows.Count - 2; i++) {
string mynodetext = ((Excel.Range)worksheet.Cells[i + 2, 3]).Value2.ToString();
string mynodetext1 = ((Excel.Range)worksheet.Cells[i + 2, 4]).Value2.ToString();
if (treeView1.SelectedNode.FirstNode.Text == mynodetext) {
this.richTextBox1.SelectedText += Environment.NewLine + mynodetext1 + Environment.NewLine;
}
}
How to get correct selected Node.

I'm having a hard time figuring how to get my imagelist index 3 icon to display in the nodes "N1" and "V Speeds" below? So, as you can see in the attachment, the closed folder icon is currently shown which is index 0 in the imagelist. But I want index icon 2 to show in these two nodes.
treeView.BeginUpdate();
treeView.Nodes.Clear();
treeView.Nodes.Add(new TreeNode("Checklist"));

i am facing some problem with qsort() function it work well if the last element of array is larger then the 2nd last element. But in case if last element of array is smaller then the 2nd last it will sort the whole array and remains the last as it is. For example
Code:
int group_id_local[max_j]={2,1,4,5};// it work fine, output should be {1,2,4,5} but if i have this one
int group_id_local[max_j]={2,1,4,3};
// output should be {1,2,4,3}
/* COMPARE FUNCTION FOR USING QSORT()*/
int cmpfunc (const void* a, const void* b)
{
if (*(int *)a < *(int *)b) return -1;
if (*(int *)a > *(int *)b) return 1;
return 0;
[Code]....
why it will not sort the last element?

I'm having trouble with getting a sine function to work. All variables are defined earlier in the same section. I have the code in a button (where I figured it would go) but I get the following error:
WindowsFormsApplication2.Math does not contain a definition for 'Sin'
For reference, I am using Microsoft Visual Studio Express 2013, and am coding a Windows Forms Application.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
[Code] ....
I've tried other functions as well (abs, sqrt, etc.) to no avail, as Math only seems to pop up with two options: Equals and ReferenceEquals.

I have written a delete node function to delete a node in a linked list by the index number. Here is the code:
Code:
void delete_node(struct node **start,int index_no)
{ int counter=0;
struct node *current=*start, *prev=NULL;//Current holds start and prev holds previous node of current
while(current->next!=NULL)
[Code]....
note that I know if the head node turns out to be the indexed position, there is no way to delete that node in the current coding. But please after correcting the present node add that part of the code separately.

We have to make a function integrate to work with the other functions given. I had it working before but I would only get all -4 as my answers but only the first one should be -4. what should more or less be put in my integrate function?
#include <iostream>
using namespace std;
typedef double (*FUNC)(double, double, double) = (line, square, cube);
double integrate(double FUNC, double a, double b){
for(int i=0; i<a && i<b; i++){
FUNC = a-b;

void Quicksort(int info[],int left,int right){
int pivot = left + (right - left)/2;//it is the middle (will change sometimes but will end up in the middle
int temp;
while(left<=right){
while(info[left] < pivot){
[Code] ....
This is my quicksort function. I have tried a lot of things but I am trying to get it to work to sort all the details I have stored in an array by there age. This is how I have entered the data.
void DataEntry(Details info[],int size){
int x;
int i;
i=0;
cout << "How Many Entries Would You Like to add";
[Code] ....
I am stuck on what to do with it

Code:
struct lista* del(struct lista* p, char* path1) {
char model[MAX2];
int len;
char ch;
printf("Type model.
[Code] ..... t
This function should delete each element in the list which is the same as this one typed by user. There are no errors, but function doesn't work. It deletes something, but not this element which should.

I have the following function I would like to convert to work with std:string. I don't understand QT strings at all.
Code:
void FromHexString(const QString &hexText, void* pData, int dataSize) {
for (int i = 0; i < hexText.length(); ++i) {
bool ok = false;
((uint8_t*)pData)[ i ] = hexText.mid( 2*i, 2 ).toInt( &ok, 16 );
}
}

I wrote a function to count the number of characters in a string. Curious as to why I have to return x-1 and why x isn't the number of characters.

57 p = string;

while (innerCount <= count) {
cout << "@";
innerCount++;
} cout << endl;
count++;

I have a very big xml file. I read it using by xmlReader. I have problem when i reach to next line:
<title>Abasia<nemod>(-astasia) (hysterical)</nemod></title>
How I can read all that content. I have to have next string at the end: "Abasia (-astasia) (hysterical)".
I tried to use ReadElementContentAsString() for all elements, but elements like this has exception, because it has child element.

I tested my count funtion. So my count function is not working properly, it should return 5 because 5 words have prefix "tal," but it is giving me 10. It's counting blank nodes.
This is my main.cpp file
int main() {
string word;
cout<<"Enter a word"<<endl;
cin >> word;
string filename;

We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.

struct node{
//data
node* root, *left, *right;
}
why not
struct node{
//data
node* *left, *right;
}
node * root;
whats the difference?
