C++ :: Algorithm For Letters Used In Hangman Game?
Jun 2, 2013designing an algorithm forHangman game.
I've got everything I need that is expected of my program except this.
When the user starts the game they will have these letters available to them:
"abcdefghijklmnopqrstuvwxyz"
Now if they were to guess 'a' it should look like this:
"-bcdefghijklmnopqrstuvwxyz"
then if they were to guess 'k':
"-bcdefghij-lmnopqrstuvwxyz"
and so forth.
C++ :: How To See STL Elements Realization
Jun 23, 2012As far as I'm understand we have only access to .h files of elements of STL. So other words in MS VC 2010 we haven't opportunity to see exact implementation of elements of STL. Where I can find implementation of STL elements or substitute algorithm that do the same thinks like stack from stl

Mar 29, 2014I am creating a reaction game using a series of lasers and LRDs and need to make a function which waits for a specific pin in portb to be triggered high before it can move onto waiting for the next pin to be triggered. The time lasped before the "game loses" needs to get exponentially faster as the game goes on.

C++ :: Strategy Pattern Paradox - Algorithm To Decide Winner Of The Game
Feb 6, 2015I've reached some sort of paradox while writing my small game. I need an algorithm to decide the winner of the game, but it's a fairly complicated task so i decided to delegate the responsibility to a strategy object, and code a naive(inefficient) algorithm to begin with, then i can easily swap the algorithm for a more efficient one later.
The problem is, that the strategy object needs to know the game, and the game needs to know the strategy object, but as you can see there is no way of doing that since i need to create one object before i create another.
//Wrong code illustrating the concept
Winner_strategy * winner_strategy;
Game * game;
winner_strategy = new Winner_strategy(game);
game = new Game_impl{winner_strategy};
BTW i know that it's best pratice to use unique_ptr, but i don't think it will make a difference here?
C++ :: Game Design Practice For Accessing Container Of Game Objects
Dec 21, 2014I'm working on my first video game. So far I have a few classes in the game starting with the Game class which includes a list of GameObjects (another class). There are several classes that inherit from GameObjects used to implement things like bullets, explosions, various enemy types, etc.
The game essentially iterates through the list of GameObjects to update/render them. I would like to provide access to the Game's list of GameObjects inside another class (like the Bullet class) so I can put new objects on the list. For example, when a bullet hits, I want to add an explosion to the Game's GameObject list it can be updated/rendered.
How this should be setup? I was considering adding a pointer to the Game or GameObject list to the GameObject class (and methods to access it), but I was wondering if there is a better way to set this up?

C++ :: Algorithm For All Possible Combinations?
Mar 7, 2013A few days ago I got a "bright idea" to see if I could match a string, with an arbitrary length from 1 to 12, to its formulated sequence by using an algorithm to find all possible combinations of the integer combinations from 0 to 9 at each length (1 to 12).
Example: Desired numerical combinations from integers 1 to 3:
At Length 1:
1, 2, 3
At Length 2:
11, 12, 13, 21, 22, 23, 31, 32, 33
At Length 3:
111, 112, 113, 121, 122, 123, 131, 132, 133, 211, 212, 213, 221, 222, 223, 231, 232, 233, 311, 312, 313, 321, 322, 323, 331, 332, 333
And so on until the nth length (in my case a length of 12).
First off, I would like to say that this is not as easy as I thought. I clearly underestimated the problem seeing as I've spent hours attempting to write a working algorithm, but feel like I've made no progress.
Here are a few of my attempts:
Attempt 1:
#include <iostream>
#include <algorithm>
#include <math.h>
#include <string>
[Code]....
I can't exactly explain this one. It works if the length is 2 or less; however, the order of the output is horrendous.
Attempt 3: I tried using recursion, but only found myself getting more and more lost the further I tried developing my function. Cannot find my work for this attempt.
I would really like to figure this out on my own, but I am very stuck as you can see. I also lack time that I can spend working on this since im a full time student.

C++ :: Simulated Annealing Algorithm
Mar 10, 2014I'm still a beginner at C++ programming, I have tried to implement some optimization algorithms (related to database) in C++, I cannot say it is going as far as I thought it will be, some errors does not even make sense, I will cut to the chase, I need to implement SA (Simulated Annealing) in C++, SA, which is an example of the Randomized Algorithms, functions on the concept of randomness and probability. In addition, I searched the internet with no (let say "accurate") code that might give me insight on how to begin, I only found one code for SA that I could understand, and edited it (which will be shown below), still looking to enhance and correct it more.
The code for SA is as follows:
Code:
#include "stdafx.h"
#include <iostream>
#include <time.h>
#include <stdlib.h>
#include <cmath>
[Code] .....
If the concept of Simulated Annealing is not clear, you may refer to the following papers which can be found in a simple Google search: Simulated Annealing Algorithms: an overview.An Introduction to Interacting Simulated Annealing. Query Optimization (there is a sub-section for Simulated Annealing in this paper that explains SA briefly) ....

Mar 25, 2013I'm trying to implement the flocking algorithm in C++. I've tried to implement it myself by making all the particles 'home-in' on the player. When 2 particles then collide within their larger bounding boxes they home-in to each other. And when the 2 particles are actually touching they repel each other until they are outside of their bounding boxes and find another particle to home-into.when I run my application the particles all home into the player and come to a stand still along the Y-axis above the player.
All the particles in question are stored in a Vector, with a pos and velocity.

Feb 6, 2013I've been stuck on a divide a conquer algorithm problem for about an hour now, and I'm not sure how to solve it. I need to use divide-and-conquer to implement an algorithm that finds the dominant element of an array of positive integers and returns -1 if the array does not have a dominant element (a dominant element is one that occurs in more than half the elements of a given array).
No sorting may be used, and the only comparison that may be used is a test for equality.
I understand the general process I need to follow to solve this problem, but I'm not sure exactly how to convert my thoughts to code. I know that if a number x is the dominant element of an array A, the x must be the dominant element in either the first half of A, the second half of A, or both.
Here is what I have so far.
#include <iostream>
#include <string>
#include <vector>
using namespace std;
int find_dominant(int *A, int p, int r) {
[Code] ....
The program must run in O(n log n) time.
