Basically, my function receives an array. For example:
u8 array = {1, 2, 3, 4, 5}
I don't need the first 2 elements, how can I access the array's 3rd element as head? I plan to throw the received array to another function.
array = array[2];
somefunc(array);
Will somefunc get index 2 as start of the array?
i want to make moving button or moving box clickable as i am making a game in which i move picture boxes and user clicks on it and his scores increases. but i was unable to do so , so i tried the same concept with buttons but no results.

I need so swap this whole rows. I'm using dynamic array. So my question is Do I have to do a bunch of temps to move them? Or is there a way to move the whole int array row as a single unit?
I want to make an object in array[][] move
Ex:
array[2][5]
array[0][0] = 'O'
O| | | | |
| | | | |
| | | | |
then
|O| | | |
| | | | |
| | | | |
then
| |O| | |

how can i print my array in console then change&print it again, then change&print it again,... So it look like O is moving

im trying to get my array to display 5,1,2,3,4 from the original 1,2,3,4,5.
void values::movevalues()
{
cout << "postcondition
";
[Code]....
something in this part is making it go wrong, it displayes the original array fine but when it tries to shift it it goes haywire. EDIT: also how would i add elements onto the array?
This is for a class project. I am having trouble "pulling out" the last element in my array, shifting all the elements back then inserting that last value in the front. Then also displaying the array after the shift. here's my code.
#include "stdafx.h"
#include<iostream>
using namespace std;

URL.....Now, I am trying to model "light" inside the world[20][20] char array by using a char light[4][4] which only opens up the map in enclosed in the light area of effect. In this case 4x4. I have tried quite a few things, including 4Darrays, but nothing comes close. Essentially, I want to be able to move the light[][] array freely inside the world[][] array centered at some arbitrary point.

Starting on p. 110 the book instructs how to develop a JSON file that will be read by the map application on the website: Geo-locater. Starting from a file containing the values of the latitude and longtitude in CSV format a C program is developed to convert it into a JSON file. Up to this point everything worked perfectly although I doubt whether the generated output file conform with the standard of JSON files due to my lack of knowledge. The problems begin after the previous step. First of all, when I try to save the webpage as a whole (from Chrome, Firefox on Ubuntu 12.04.3 32-bit and Windows 7 64-bit) the local copy of the map.html file is useless. When the file is double clicked a white blank page is displayed with no map to be seen. However, when it is saved with the only html file option the map is displayed but the JSON file in the same directory is not read by the program to display the corresponding red markers. What may be the reason behind this and how can I remedy the situation? It has been bugging me a lot these days.
The corresponding files are as follows:
"output.json" Code: data=[
{latitude: 42.363400, longitude: -71.098465, info: 'Speed = 21'},
{latitude: 42.363327, longitude: -71.097588, info: 'Speed = 23'},
{latitude: 42.363255, longitude: -71.096710, info: 'Speed = 17'},
{latitude: 42.363182, longitude: -71.095833, info: 'Speed = 22'},

{latitude: 42.363037, longitude: -71.094078, info: 'Speed = 16'},

Code:
42.363400,-71.098465,Speed = 21
42.363327,-71.097588,Speed = 23

P.S. I have done exactly as told in the book and I am very unfamiliar with JS. Note that I have also asked the same question previously on Stackoverflow.
i am trying to develop a doubly linked list class. I became stuck at a few of the functions as well as the main.cpp file. i have to insert a character sentence "TRICK OR TREAT" spaces included. I am stuck on the display and the listsize functions and im unsure if my insert has the head node in it. The function parameters were given to us and most of this code was given from a single linked list.
//node.h
#pragma once
class Node
{
publi
[Code].....
I would like my function to return the data that was deleted. I have this code at the moment, where value_type is just an alias for int at the moment:
node::value_type linkedlist::removeFromHead(){
node* temp_head;
node::value_type data;
data = head_ptr->getData();
[Code] .....
When I try to use this function though, I get a segfault.
I am attempting to change the value of the head node in my list. I thought due to having pointer defined in parameter list I could change the address value of head node. The argument passed is a struct I did not have to use & in argument list to denote address of struct to compiler. This may have something to do with my problem. I did not include all routines called by main program just the deleteNode routine im having problems with.
bool deleteNode(struct node *head, struct node *delptr) {
node *cur = head;
node *tempNextptr= cur;
using namespace std;
while(cur) {
if (cur == delptr)

I have a main.h file where I include all the needed things to make my program compile properly, string, vector etc.
And I also have another header file which comntains a class that is used later in the code (globally), I decided to keep it in another file to make it more clear and easier.
I need to include that file in main.h, but I also include main.h from that class header file because it contains some other includes that are required to compile.
Is this a good thing? Or should I keep main.h out of that class header file and include just things required for the class?
I may have complicated it too much, so I'll show an example, what I do now:
// ---- main.h ----
#include <string>
#include <vector>
#include <ctime>
// other includes, these are just examples
#include "MyClass.h" // the separated class header file
[Code] ......
So, from what you can see MyClass.h requires just including the vector, but to avoid repeating myself I include main.h which does that already, but also includes MyClass.h
So, I have two questions:
1. Is it ok to include in that way (including a file that includes the including file)
2. Is it good to include a main header file with all the includes even if I just need one of them, or should I skip including main.h and include just the things my class requires (vector is just an example)
From HP / Microsoft (Visual Studio C++) <list>:
Code:
struct _Node
{ // list node
_Genptr _Next; // successor node, or first element if head
_Genptr _Prev; // predecessor node, or last element if head
_Ty _Myval; // the stored value, unused if head
};
The stored value is wasted space for the list head. Is there any advantage to implementing list using the same structure for a list head and node?

I am not so experianced with c++ myself, but I need to evaluate if a certain idea might work.
I am working with a system for automation purposes that is running on a realtime OS in parallel to windows. Windows and the RTOS exchange data via shared memory. The application in the RTOS is compiled in C++. Now I would like to be able to influence the some data manipulation tasks in the RTOS application without changing the code of the RTOS application. So a concept like calling a dll.
My idea was to create a class with virtual methods in the RTOS application. The objects that are used should then be created on the Windows side with the same class prototype, but specific implementation of the virtual methods. The objects should then be moved to the shared memory, where they are used by the RTOS application.
Is something like this possible or am I completly on the wrong path?

I'm working on designing a game in C++ that is similar to the "find the ball under the cup" game. I have a Sonic the Hedgehog icon (weird I know, but it was the first thing that came to mind) that will be hidden underneath one of three rectangular blocks.
Here is how I envision this working:
On the main menu I have 3 buttons which represent 3 different difficulty levels
Easy- blocks move 3 times at a slow speed
Medium- blocks move 5 times at a slightly faster speed
Hard- blocks move 10 times at a fast speed
When the user clicks one of these buttons they will be taken to the game screen.
Sonic will be displayed for 3 seconds and the user will then see him be covered with one of the three blocks.
The three blocks will then move in a random pattern along the middle of the screen at the speed and number of times associated with the button that was pressed.
Once the blocks stop moving, the user is to click on the one they think Sonic is underneath.
If they choose correctly, they'll be taken to a "Winning Screen" that displays a congratulatory message and 2 buttons. Play Again- returns the user to the main menu and the game starts over with a new random pattern. Quit- the window closes.
If they choose incorrectly, they'll be taken to a "Losing Screen" that displays a "Try Again" message and 2 buttons that have the same function as the buttons on the winning screen.
I have never worked with any kind of graphics before other than in HTML and Javascript. I have managed to create the main menu, but how to do the actual game portion of the project. I've been trying to take it a step at a time, (for example, I first figured out how to set the background color for the console window, after I got that right I figured out how to add buttons) but the rest of this seems to depend on each other.
Here is what I have so far:
Main menu:
#include "stdafx.h"
#include <iostream>
#include <Windows.h>
using namespace std;
class MainMenu
[Code]....
So I've got the screens pretty much designed now (with the exception of the game screen itself) but how to tie everything together.
In case my description wasn't too clear, here is a game that I found on Google that is pretty much exactly what I'm looking for. [URL]
I need the number of moves to reset to zero every time because right now when when i enter the next number of disks the moves from before are added to the new set of moves. Here is my output
how many disk are you going to start with? 2
It will take 3 moves
how many disk are you going to start with? 2
It will take 6 moves
how many disk are you going to start with? 2
It will take 9 moves
how many disk are you going to start with? 2
It will take 12 moves
how many disk are you going to start with?
the number of moves for 2 disks should be 3 but as u can see every time i enter 2 disks it just adds to the last number of moves how can i fix this ?
