I looking for method which can give me the height difference of an AVL_tree.
The method i come up with up now is this.
int avl_tree::balance(node* pointer)
{
while (pointer->left != NULL) {
int left = balance(pointer ->left);
}
while (pointer->right != NULL) {
int right = balance(pointer->right);
}
return left - right;
}
Which recursively calls itself, but the problem is that i get stuck on the first line..
I understand that I have to find the height by using _left->height() and _right->height() as long as it is not a null-pointer , each time I do this the values of _left and _right change. That way you can check if it is possible to go further down in the tree. I also have to use a counter to keep track of the number of layers at each side of the root. I don't understand how to implement it.
I am having trouble with calculating the volume of a cone
Assignment: Using the knowledge you already have, create, build, run, and correct if necessary a program that will calculate the volume of a cone. Insert into your code values for diameter of the base and the height. Use variables, constants, literals, and mathematics as necessary.
The formula for the volume is:
1/3 π x Radius2 x Height
Hint: you will need to add to your program two lines where appropriate:
#include <cmath> const double PI = 2*acos(0.0);
Here is my current code:
#include <iostream> using namespace std; int main () { //diameter of the base float diameter = 3;
I'm challenged to write a program which calculates the time difference between two daytime.
compiler doesn't give an error, yet the warning: "format '%d' expects argument of type 'int *', but argument 3 has type 'int' [- Wformat]" for lines 24 and 26
However, by entering the first time the program crashes anyway. so I assume I do really need some pointer to make it read from the console can you see where my problem is?
Code:
#include <stdio.h> #include <stdlib.h> typedef struct { int Second; int Minute; int Hour; }Time;
Basically when I type in different widths and heights for the col and rows, the buttons that make up the width get cut off. Something is messed up but I'm not sure what!
InitializeComponent(); int _col = int.Parse(cols); int _row = int.Parse(rows); int width = groupBox1.Width; int height = groupBox1.Height; int bW = width / _col; int bH = height / _row;
Is there a way to set the height of a listBox to show all of the items without having to kick in the vert scrollbars? I've searched on this question but can't find how to do this.
I want to kind of auto-size my listBox height to accommodate my items (within reason and perhaps set a max height which would kick in the vert scroll bars.
Define functions n(), s(), e(), w(), center(), ne(), se(), sw() and nw(). Each takes a Rectangle argument and returns a Point. These functions define connection points on and in the rectangle. For example, nw® is the northwest (top-left corner) of a rectangle called r.
I wrote below code for that:
#include <Simple_window.h> Point n(const Graph_lib::Rectangle& r); Point s(const Graph_lib::Rectangle& r); Point e(const Graph_lib::Rectangle& r); Point w(const Graph_lib::Rectangle& r); Point ne(const Graph_lib::Rectangle& r); Point se(const Graph_lib::Rectangle& r);
[Code]...
As you see, this just mark the top-left corner of the rectangle r. In other functions I need the specifications of that rectangle, for example its height and width. How to use these specs in those functions?
In a MDI-app with some toolbars and statusbar I created also a controlbar which can be docked to the left side. My problem now: how do I get the exact height of the controlbar?
In CalcDynamicLayout I set the height for the docked state to the height of the mainframe. This value is too big, but it will work basically.
But how can I get the exact height of the controlbar?
I am attempting to write a simple C program, in which the user is asked to input their name and height in inches and the output is the user's height in centimeters.
I have attached my program and what happens when I try to run it.
I need a ownerdraw CListBox where I can change the item height during working with the list. The msdn says that I can specify the height in OnMeasureItem when the listbox will be created (ownerdrawfixed) or when an item will be inserted (ownerdrawvariable).
How to change the height e.g. when I click a button?
I made also some tests with CListCtrl. There I can change the height. But there is only one height for all items. How to set individual heights for the items?
How would I make it so that I can have someone input the length, width and height for all 3 boxes and then have it output the sum and average volume? Here's an example of what I would like:
INPUT - Enter Box 1 (Length, Width, Height): 10.1 11.2 3.3 INPUT – Enter Box 2 (Length, Width, Height): 5.5 6.6 7.7 INPUT – Enter Box 3 (Length, Width, Height): 4.0 5.0 8.0 OUTPUT – The sum of the volume is 812.806 OUTPUT – The average volume is 270.935
Here's my original code:
#include <iostream> using namespace std; double box(double length, double width, double height); // use double data int main() { double sum; sum = box(10.1, 11.2, 3.3) + box(5.5, 6.6, 7.7) + box(4.0, 5.0, 8.0);
Provide the definitions for the following class declaration and then write a program that demonstrates usage of each member function using the test data of 10 for width and 8 for height. Remember to put your main program, class header and class source into separate files. This is an easier version of the exercise than the one you have been asked to practice. Only provide code for the methods specified in the class declaration. Note that the displayRectangle() method should output an appropriate ‘box’, its dimensions, area and perimeter to the screen.
class Rectangle { public: Rectangle(int height, int width); ~Rectangle(void);
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*)'
Creating a C# program to prompt the user to choose the correct answer from a list of answer choices of a question and if the answer is wrong then try to prompt the same question again with do while loop but it is not working as it suppose to be.
class Program { static void Main(string[] args { char UserChoice = ' '; do { Console.WriteLine("What is the command keyword to exit a loop in C#?"); Console.WriteLine("a.quit"); Console.WriteLine("b.continue");

But if i use int instead of char in this program and replace a, b, c and d with 1, 2, 3 and 4 then this program work fine. What is wrong in this code when using char
