C++ :: Empty Elements Of A Stack Into A Queue
Apr 3, 2014So I was wondering if I were to empty the elements of a stack into a queue, but i only wanted to empty the even numbers or the odd ones. What would the if statement be to accomplish this. Im guessing for even it would be something like if(number % 2!=0)? What about for odd?

Sep 13, 2012Use your language’s native queue class to write the following program: create a class, Patient. The class has 2 members: name of type string; wait_time, a non-negative integer. Read definitions of patients from a file and add the patients to a queue. Write a loop that dequeues a patient from the queue and then decrement the patient’s wait_time. If the patient’s wait time is greater than 0, then the program enqueues the patient again. Otherwise it discards the patient. The loop continues until the queue is empty.
Header File
Code:
#include <string>
class Patient {
public:
Patient();
std::string name;
int wait_time;
bool empty() const;

C++ :: Increase Sizes Of Queue In A Vector Of Queues And Find Shortest Queue
Feb 20, 2013I have a paradigm in a loop of queues of a vector,if a condition is true,increase sizes of the queue of that particular queue in the loop of queues, if condition is false, the queuesize is left as such in loop of queues. After this operation i need to search the queue sizes of all queues and enqueue in the shortest queue.
I want to do something like the code given below
#include <vector>
#include <queue>
int min_index = 0;
std::vector<std::queue<int> > q
std::size_t size = q.size();
[Code] ....
How to implement this logic?
will q[i].size=q[i].size+5 increase the queuesize by 5 for the ith queue?
C/C++ :: Linux Console Get Key State

Mar 27, 2014I thought that an operator performs a permanent change in a local variable. For example, if x is 00000000 00000000 00000000 00000011 (a 32 bit unsigned integer that resolves to value of 3) and p is 2, in the expression "return (x >> p) | (x << (s - p))", the right shift would permanently change x to 0 and the time we evaluate x again in "(x << (s - p))", x will already be 0. If that's the case, then this function doesn't make sense. This function makes it seem like that the >> and << operators do not change the value of x. It makes it seem like first we right shift x to 0 and then left shift by 20 bits to make x 11000000 00000000 00000000 00000000. If that's the case, then the function does exactly what it is supposed to do (rotate the bits). So which is it?
unsigned int rightrot(unsigned int x, unsigned int n) {
size_t s = sizeof(x) * CHAR_BIT;
size_t p;
if(n < s)
p = n;

C++ :: Changing State Names To Abbreviations?
Feb 13, 2014The purpose of the code is to read in state names, say california and print CA. However, if it was a state with two words, it would read in only the first letter of each. I.E New Hampshire would be NH.
here's my code:
#include <iostream>
#include <iomanip>
#include <cctype>
[Code].....
I am able to get the one word states and tried getting the two word states but it doesnt work.

C/C++ :: Reverse A String And State If It Is A Palindrome
Mar 28, 2015I am supposed to take the three string lines from a text file and then individually reverse them and state whether or not they are a palindrome. I have the three lines from the text file into string variables already but I am not sure on how to reverse them and then see if they are the same reversed(palindrome)
Here is my code so far -->
#include <iostream>
#include <string>
#include <cctype>

EDIT: Ignore line 123 and down in the code. That was merely test code and will not be used.
C++ :: State The Values Of Each Int Variables After Calculation Is Performed
May 2, 2013Question: State the values of each of these int variables after the calculation is performed. Assumed that, when each statement begins executing, all variables have the integer value 5.
a) product *= x++;
b) quotient /= ++x;
What is the answer for a and b?
Visual C++ :: Debugging - Revisiting Same Memory State?
Oct 31, 2013When running my code in Visual Studio, there is a particular point in the code where my program is crashing. To debug this, I am adding a break point in Debug mode just before that point, and observing what happens as I step through the code. However, to get to this break point in the code takes about a minute of running the program. So I'm wondering if there is a tool in Visual Studio to reload the state of a program's memory from a previous run, so that I can immediately get to the break point without having to wait for a minute each time?

May 5, 2014I am trying to initialize this chunk of code without it starting at the main menu in my state program:
boost::asio::io_service io_service;
tcp::resolver resolver(io_service);
tcp::resolver::query query(argv[1], argv[2]);
tcp::resolver::iterator iterator = resolver.resolve(query);
chat_client c(io_service, iterator);
boost::thread t(boost::bind(&boost::asio::io_service::run, &io_service));
char line[chat_message::max_body_length + 1];
This code came from a example at the boost example list: URL.....I want the networking to start when the multiplayer state initializes. This is how my program basically looks like:
//Main.cpp
main() {
if (!quit) {
while( handleing_events ) {
CurrentState->handleEvents();

I tried to put the stuff in extern at states.h, and initialize it at Multiplayer(), but in handleEvents & ~Multiplayer, it says "c" is not defined...
C++ :: State Design Pattern - Calling A Class Member
Oct 17, 2013In the following code example of the State Design Pattern, in the main code at the bottom it defines an instance of class Machine, and then calls Machine::off;. Why doesn't it instead call fsm.off;?
Machine fsm;
Machine::off;
Then I tried imitating that by adding a class Abba, and then doing:
Abba a;
Abba::DoStuff();
but that didn't work. Why?
Full code example:
// StatePattern.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include <iostream>
using namespace std;
class Machine {
class State *current;

C/C++ :: Circular Buffer In The Form Of Finite State Machine
Dec 11, 2014I'm supposed to create a circular buffer that reads an input file and outputs data after running though basically an integral equation. Everything my be referenced by pointers. When I build I am being told segmentation fault: 11. From what I have gathered that means there is a problem with my memory allocation correct? I'm including the custom header file and the main.c as well.

class Foo {
};
int main() {
Foo foo;
std::cout << sizeof ( foo ) << std::endl;

produces this result: 1
Why is the size of an instance of Foo 1, although it doesn't have any member variables?
C++ :: How To Declare Empty Method
Oct 11, 2013It has been a few years since I have had to do this, but I need to declare a method in my base class, but produce no code for it. Then when this library is used by my second project I will derive a class from this base class and put the code into it there. How is this possible? I used to know how but do not remember how now.
The library is a static library designed for linking with both 32bit and 64bit Windows applications to handle a lot of the tedious stuff with Windows programming. The method in question handles specific command inputs. However, since each program that uses this library will have different uses for these commands, I want to leave it up to the user to code their own handling, but require it to be coded in the derived class.

Mar 16, 2013I've been trying to figure out how to implement a way to save this board state throughout a user's inputted path. At the end, I need the output to print out the board states (user's path) of how he or she got the puzzle solved. This puzzle is the 15 Puzzle; but we have it to change by the user's input on what size they want to play (3x3 to 5x5). How to save the board state of each user input, then print those out in order from beginning to solved puzzle state. Subsequently, I would also need transferring the board state to change with using a vector to store the size based on user input. How to proceed, using a first search to solve the puzzle from the current board's state.

Code:
/*Calculations set as a header to keep compiling simple and faster*/
#ifndef calculations
#define calculations
int solved[5][5];
void initialize(int board[][5], int);
void slide(int board[][5],int move,int);
