Nov 26, 2013I'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) {

return false;

C :: Creating PPM Image - Black Rectangle With A Circle
Mar 12, 2013I'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.
C :: Creating Black Bitmap - How To Set Color Of Individual Pixel
Nov 2, 2014creating a bitmap. Our professor wants us to creat a black 100*100 bitmap.
Code:
#include <stdio.h>
#include <stdlib.h>
#pragma pack(push,2)
typedef struct{
[Code].....
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 ?
C :: Calculate Black Body Spectra Over User-entered Range Of Wavelength And Temperatures
Jul 29, 2013I 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>

Dec 10, 2013So this is my first try animating on my own, without a reference right in front of me. It's not working, I did check some of the projects I've made in the past, but for one those were done with Allegro, and really it should be able to move over to SFML quite easily, but it's not. It does display on the window in the correct place, but there are 3 pictures in the file and I want it to cycle through them, but it shows all three at the same time, and it only works once. if I press space a second time, only one of the pictures shows up, and it doesn't cycle at all. Here is my .cpp file :

C++ :: OpenGL Preserve States (SFML)
Feb 12, 2013So I did read, however it said also that it was memory intensive and I had a question... I also came across this:
Window.pushGLStates();
Window.draw("Sfml Text");
Window.popGLStates();
The problem here is that none of these commands exist!
Window.draw should exist and even though I have all the proper includes I still get it telling me that 'Draw' is not a member of sf::Window
I have encountered that error many times everywhere across my sfml related code, it's not like they removed all those features in the update (Which they did not) but, why then would it not be a member?
