C++ :: Create Binary Search Tree Template To Be Used To Create AVL Tree
Feb 10, 2013For 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*)'
Stemming from the call in main line 16.
my makefile compiles with:
g++ -Wall -g Generic_Tree.cpp BST.cpp barfing.cpp main.cpp
Generic_Tree:
template < typename NODE_DATA, unsigned MAX_KIDS >
class Tree {
protected:
struct NODE {
NODE_DATA* contents;
Tree* child[MAX_KIDS];
Tree* parent;
[Code] ....
I'm use to c and havn't used classes or templates before (except for declaring instances of them). The whole syntax is mystifying to me,.

C :: How To Create An Object
Oct 31, 2013I have an assignment that asks me to implement a variant of the classic bouncing balls program.
'Each ball should start off at the top of the screen with a random speed in the x direction. Whenever a ball hits a screen boundary it should bounce off at an angle equal to the impact angle and lose some speed. Eventually each ball should come to a rest at the bottom of the screen. Five seconds after coming to a rest a ball should be removed from the screen.'
'Your code must keep track of objects (balls) by placing the object data structures in a linked list. You need to create your own linked list implementation. Below is a brief description of the object programming interface: CreateObject - Create a new object. The function accepts as input parameters a pointer to the SDL screen, a pointer to a model triangle array, and a variable telling the size of the model triangle array. The function returns a pointer to a new object data structure. The model triangle array specified as input parameter should not be shared across objects. (Not sharing the model triangle array allows e.g. objects to have different colors.)
Perform the necessary memory allocation and copying.DestroyObject - Free object. The function accepts as input parameters a pointer to an object data structure. The function should free all memory allocated to represent the object (memory allocated for the model triangle array and the object data structure itself).
Drawobject - Draw object on screen. The function accepts as input parameters a pointer to an object data structure. The function must draw the object on the screen by calling DrawTriangle on each of the model triangles. Remember to update scale, translation, etc., in each triangle data structure before invoking DrawTriangle.
Hint: Do not make the bouncing algorithm too complex. Bouncing a ball off a vertical or horizontal surface can be accomplished without resorting to calculating impact angles.'
The function I'm stuck at, is the first one - createobject.
My first aim is to get one ball on the screen.
Code:
// Create new object
object_t *CreateObject(SDL_Surface *screen, triangle_t *model, int numtriangles)
{
object_t *object = malloc(sizeof(object_t));
object->model = malloc(sizeof(sphere_model));
object->screen = SDL_Surface;
memcpy(*model, object->model, sizeof(object_t));
return object;
// Implement me
}
This is what I've done so far.

C++ :: How To Create A Database
Feb 28, 2013I'm trying to make a database that stores the information without overwrite it. I want this program to store the client’s selection in somewhere that doesn't change and also that creates a new storage for the new value any time the client enters a new selection instead of overwriting it. I did something like that in my code but any time the program runs again and the client enters a new selection, the client’s selection is overwritten with the new value. I don’t know if it’s possible to do that (store the client’s selection in somewhere where doesn't change) with C++. I've been reading and I think I can create a database for my program.
THIS IS MY CODE:
#include <iostream>
#include <string>

C++ :: How To Create A Singleton Class
Oct 6, 2013I've tried to program a Singleton class. But the problem is that I don't know how to access the g_pInstance() function. Because this is not working because the constructor and deconstructor is private:

I'm not sure of how to access any object, function, variables in the class when you are using a Singleton. How do you access that?
I'm just asking because I want to know how to do that if I have to use a Singleton sometime when I'm programming.
C++ :: How To Create Array Of Nodes

/*This is a template of a person....sorta*/
class person{

int data[32];
bool selected = false;
person(){

C :: How To Create A Program That Take AVI File
Jan 26, 2015I want to create a program that would take an AVI file, alter each frame (ex: change contrast, invert colors, etc.) and dump a new AVI. I've wrote a simple program for this experiment that loads up the header information from the video and dumps it. It also dumps a list of the frame data chunks within the 'movi' chunk.
The info I've gathered from coding this:
1. The recommended buffer size for each type of stream (vids, auds, etc.) is the size of the largest frame of corresponding type, plus 1 or two extra bytes.
2. numFrames in main header is the total number of frames for all types of data (video,audio,etc.) The 'length' value within stream header of type 'vids' is the number of video frames. The sizeImage value within BITMAPINFOHEADER is 921600 (==640*480*3) and the specification states that, quoth, "This can be set to 0 for uncompressed RGB bitmaps."
3. This video uses DIVX encoding.
Now my problem is this: How do I get the data within each video frame in a simple BMP like format? Even the uncompressed frames (with chunk id 'nndb') have variable sizes...let alone the compressed ones.
Information about a software that converts AVIs to a format with fixed sized uncompressed frames. Or at least some information about the frame decompression techniques.
Here's a dump made by the program for a 9 sec, 640x480 video I recorded from Pokemon. (Without the frame dump that is, it'd have made the post too long.)
Code:
AviMainHeader
-------------
size = 56
usecPerFrame = 66666
maxBytesPerSec = 7680000
padSize = 0
flags = 0x00000810
numFrames = 162
initialFrames = 0
numStreams = 2

C :: How To Create Array Of Arrays
Nov 3, 2014I wanted to do this: Accept a line of input from user and save it to an array1 and copy its contents to other array in a set of arrays and then input another line to array1 and then copy it to next array in the same set and so on.... I know it is confusing but I can put it like that I want to create an array of arrays (Set of arrays). How can I do so?
I wrote a code to input the line in an array and tried to copy it another array of pointers, but pointers are just addresses so the same adress is copied again and again so, all the pointers of the array point to one address only. The code doesn't print anything when I try to print all the lines that were saved.
Code:
#include <stdio.h>
#include <stdlib.h>
#define MAXLEN 1000
#define MAXSIZE 100
int getline(char [], int );
void storage(char line[]);

C :: Program To Create 2D Array For Each Row
Feb 14, 2013What I am trying to do is to have the program create 2D array that for each row, no two numbers are the same and only consists numbers between 1-9. The array lists out every possible combinations. Supposely I do not know the number of possible combinations, I had it keep adding new rows until there are no more possiblities left.
The problem with my code is when I print out the completed array, it gives out really, really large numbers. But when I print the array from inside the first loop, it gives correct values. I do not know exactly what happened.
Code:
#include <stdio.h>
int main(void) {
