Red Black Trees. [URL] .....
My app keeps crashing after about the 49th insert.
I tried debugging and it keeps pointing to this area in the Fixup:
if (z->parent == z->parent->parent->left) {
y = z->parent->parent->right;
How to make a red and black tree using SFML ....because i really need...I really don't know how to use SFML i only know how to use win32 console.

View 7 Replies View RelatedI'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'm trying to create a PPM image for a class assignment. A black rectangle with a circle at the point 225, 175 with a radius of 75. I have to use certain specific methods, so I can't use like Bresenham's really famous method for creating a circle.
The problem is that it compiles fine, and transfers to an image fine, but always says that I have a negative or zero image size.
Code:
#include "shapes.h"
int main () {
int i, j, x, y;
fprintf(stdout,"P6 width height 255
");
[Code] ....
And my header is:
Code:
#include <stdio.h>#include <math.h>
#define height 480
#define width 640
#define cy 175
#define cx 225
#define radius 75
The circle has to be filled in. I made it white. Also, i and j are unsused so far, so just ignore them.

I dont even know where to start. I spend the last 7h infront of my computer and i'm so frustrated cause my professor gave us no information what so ever. At the moment its more of a trial and error process than anything else.
How would i set the color of an individual pixel for examplel or how would i save the file ?
I tried to write a code to calculate black body spectra over an user-entered range of wavelength and temperatures. The equation I'm trying to code is the second one this image (stolen from Wikipedia)The syntax to run it is bbgrid lambda_inic lambda_final temp_inic temp_final inc_T inc_lambda
where bbgrid is the name of the program, lambda_inic and lambda_final are the limits of the wavelenght range (in units of angstroms, 1A=10⁻⁰m), temp_inic and temp_final are the limits of the temperature range (in Kelvins) and inc_T and inc_lambda are the increments. What I want to do is, given the ranges of temperatures and wavelengths, to run the code over the lambdas and the temperatures.
The problem is that the behaviour of the intensities (what I'm calculating) is erratic. Sometimes it is highly positive, sometimes immensely negative and turning between those two. As an example of an output file, I'm getting things like this:
3100 1915076038
3110 -1233496775
3120 1741010116
3130 1229780625
3140 421722788
3150 -1874760945
3160 1654746252
3170 1062468321
3180 -795217626
3190 -1141129750
3200 -1570716956
3210 539385985
While I was trying to debug the code, I found the problem may reside in the exponential factor in the denominator. I wrote some lines to calculate and print on the screen only the exponential, and it was oscillating like crazy. The output file should produce curves like this:
Code:
#include<stdlib.h>
#include<stdio.h>
#include<math.h>
#include<string.h>

I actually think I see it now that I posted this. In operator= I'm changing the size, but I'm not changing the size of the array that it's pointing to correct? I'm keeping it as 'p = new T[size]' rather than changing it to 'p = new T[x.size]' correct?

B) how I have the method coded.

i am trying to break a string and store it to a stiva (tail) i need my program to take one function like this
(a+10)* ((b+c)/(d-5)) + (9*2)
and return if it is editorial correct for example for the apper function has to return true but for this function
((a+10)*((b+c)/(d-5)) + (9*2)
has to return false.it crashes in the last part of my list i will put a comment

I am able to add records and show records, no problem. But when I go to delete a record, it crashes immediately after inputting the record number I want to delete. I don't see why. I've set it up exactly like the example in my book, having of course changed the variable names for my program. Does it have something to do with the pointer?
When I go to run the Fibonacci function ( fib ), it begins to return incorrect calculations towards the higher numbers, but then seems to correct itself for a little bit, but then does it again and ultimately crashes. And the program seems to be crashing at random numbers. Sometimes the it will make it up to F(55), other times it will only get to F(20).
Also, when I go to run the program on a Linux server, it segfaults, but it doesn't when I just run it on my IDE. the function adds two arrays with individual digits together. It does this to allow the program to add numbers that would exceed the boundaries of INT_MAX.
Here is the header file "Fibonacci.h":
Code:
#ifndef __FIBONACCI_H
#define __FIBONACCI_H
typedef struct HugeInteger
{
// a dynamically allocated array to hold the digits of a huge integer
int *digits;
// the number of digits in the huge integer (approx. equal to array length)
int length;
} HugeInteger;
}

I started with the program I was writing and just stripped out as much as I could, while making sure the crash persisted. If I remove any of the remaining code the crash disappears, even the seemly unrelated or scoped code.

So this program I have to make keeps spitting out an error report when I try and run it. I am using eclipse C kepler.
The file it is supposed to read has the following text;

R3 N001 0 10
R4 N002 N003 10
R5 N003 N000 5
I1 0 N002 10
This program I'm working on accepts an array size from the user, prompts the user to store that many integers, sorts them from smallest to largest, and then searches for duplicates with a simple for loop. The ultimate goal of the assignment was to display duplicates in an array, and the rest of the functions are just how I decided to reach that goal.
Anyway, my program crashes if I choose an array size larger than 7. It sorts and displays duplicates perfectly with 7 or fewer arguments.
The exact moment it crashes is after I enter the final value it prompts me for, so it appears my inputsize() function and my inputarray() function are working, and the error may be in the arrsort() function. Code is below:
Code:
#include <stdio.h>
int funcinputsize(int);
void funcinputarray(int [], int size);
void funcarrsort(int [], int size);
void funcdupe(int [], int size);

The first problem i'm having is in the following code.
Code: #include<stdio.h>

#include<time.h>
// program ask for max value and always returns random numbers < max

The ultimate goal of these two programs is to merge them and make one program that takes a max value from the user and fills up an array of (10^6) elements with values ranging from (0 to maxValue).
I've been making a multilayer game for a while and have a config that the game loads for the IP and stuff. I just recently put all the loading stuff into a function just so its easier to go through the code, but now the game isn't really working. It works fine on my computer connecting to the server myself, but when someone else tries to do it it seems like the game is working like it says the IP and everything from the config. When it tries to connect it either doesn't work or crashes just saying the program stopped working. Here is the code... I don't know if this is what is causing it to not work or something else.
string LoadConfig(int &loadPort, bool &fullscreen) {
string file;
string loadIP;
vector<string> fileLines;

I'm writing a code obfuscator in C. Debugger shows no errors in the code, but the program crashes after compiling -- I'm guessing it has something to do with while loops or reading data from files.
