  • C++ Basic Class Layout

    - by Spencer
    Learning C++ and see the class laid out like this: class CRectangle { int x, y; public: void set_values (int,int); int area () {return (x*y);} }; void CRectangle::set_values (int a, int b) { x = a; y = b; } I know Java and methods(functions) in Java are written within the class. The class looks like a Java interface. I know I can write the class like this: class CRectangle { int x, y; public: void set_values (int a, int b) { x = a; y = b; }; int area () {return (x*y);} }; But is there a difference or standard?

  • Long numbers. Division.

    - by user577395
    Hello, world! I have a problem. Today I tried to create a code, which finds Catalan number. But in my program can be long numbers. I found numerator and denominator. But i can't div long numbers! Also, only standard libraries was must use in this program. Help me please. This is my code #include <vector> #include <iostream> using namespace std; int main(int argc, char *argv[]) { const int base = 1000*1000*1000; vector <int> a, b; int n, carry = 0; cin>>n; a.push_back(n); for (int ii=n+2; ii!=(2*n)+1;++ii) { carry = 0; for (size_t i=0; i<a.size() || carry; ++i) { if (i == a.size()) a.push_back (0); long long cur = carry + a[i] * 1ll * ii; a[i] = int (cur % base); carry = int (cur / base); } } while (a.size() > 1 && a.back() == 0) a.pop_back(); b.push_back(n); for (int ii=1; ii!=n+1;++ii) { carry = 0; for (size_t i=0; i<b.size() || carry; ++i) { if (i == b.size()) b.push_back (0); long long cur = carry + b[i] * 1ll * ii; b[i] = int (cur % base); carry = int (cur / base); } } while (b.size() > 1 && b.back() == 0) b.pop_back(); cout<<(a.empty() ? 0 : a.back()); for (int i=(int)a.size()-2; i>=0; --i) cout<<(a[i]); cout<<" "; cout<<(b.empty() ? 0 : b.back()); for (int i=(int)b.size()-2; i>=0; --i) cout<<(b[i]); //system("PAUSE"); cout<<endl; return 0; } P.S.

  • Can a variable like 'int' be considered a primitive/fundamental data structure?

    - by Ravi Gupta
    A rough definition of a data structure is that it allows you to store data and apply a set of operations on that data while preserving consistency of data before and after the operation. However some people insist that a primitive variable like 'int' can also be considered as a data structure. I get that part where it allows you to store data but I guess the operation part is missing. Primitive variables don't have operations attached to them. So I feel that unless you have a set of operations defined and attached to it you cannot call it a data structure. 'int' doesn't have any operation attached to it, it can be operated upon with a set of generic operators. Please advise if I got something wrong here.

  • Why can't I register a custom model binder for a List<int>?

    - by quarksoup
    I have an action that looks like public ActionResult GetUsers(List<int> userIds) {//do stuff} The list of userIds can become quite long, so I want to use Json.Net to deserialize it. To do so I created an IModelBinder implementation, which works fine for other objects, but never gets called for a List. The IModelBind looks like this public class JsonBinder : System.Web.Mvc.IModelBinder { public object BindModel(System.Web.Mvc.ControllerContext controllerContext, System.Web.Mvc.ModelBindingContext bindingContext) { //Do model binding stuff using Json.Net } } And I register this model binder with this line ModelBinders.Binders.Add(typeof(List<int>), new JsonBinder()); However the JsonBinder is never called. Why is this? Should I be using a ValueProvider?

  • how to create multiple tcp connections between server and client

    - by lowcosthighperformance
    I am new in Unix/Linux networking programming, so I have written server-client program in below.In this code there is one socket between client and server, client requests to server, then server responses from 1 to 100 numbers to client. So my question is how can we do this process with 3 socket( tcp connection) without using thread? ( e.g. First socket runs then second runs then third runs then first again .. ) Do you have any suggestion? Thank you client.c int main() { int sock; struct sockaddr_in sa; int ret; char buf[1024]; int x; sock = socket (AF_INET, SOCK_STREAM, 0); bzero (&sa, sizeof(sa)); sa.sin_family = AF_INET; sa.sin_port = htons(SERVER_PORT); inet_pton (AF_INET, SERVER_IP, &sa.sin_addr); ret = connect (sock, (const struct sockaddr *) &sa,sizeof (sa)); if (ret != 0) { printf ("connect failed\n"); exit (0); } x = 0; while (x != -1) { read (sock, buf , sizeof(int)); x = ntohl(*((int *)buf)); if (x != -1) printf ("int rcvd = %d\n", x); } close (sock); exit (0); } server.c int main() { int list_sock; int conn_sock; struct sockaddr_in sa, ca; socklen_t ca_len; char buf[1024]; int i; char ipaddrstr[IPSTRLEN]; list_sock = socket (AF_INET, SOCK_STREAM, 0); bzero (&sa, sizeof(sa)); sa.sin_family = AF_INET; sa.sin_addr.s_addr = htonl(INADDR_ANY); sa.sin_port = htons(SERVER_PORT); bind (list_sock,(struct sockaddr *) &sa,sizeof(sa)); listen (list_sock, 5); while (1){ bzero (&ca, sizeof(ca)); ca_len = sizeof(ca); // important to initialize conn_sock = accept (list_sock,(struct sockaddr *) &ca,&ca_len); printf ("connection from: ip=%s port=%d \n",inet_ntop(AF_INET, &(ca.sin_addr), ipaddrstr, IPSTRLEN),ntohs(ca.sin_port)); for (i=0; i<100; ++i){ *((int *)buf) = htonl(i+20); // we using converting to network byte order write (conn_sock, buf, sizeof(int)); } * ((int *)buf) = htonl(-1); write (conn_sock, buf, sizeof(int)); close (conn_sock); printf ("server closed connection to client\n"); } }

  • Misunderstanding function pointer - passing it as an argument

    I want to pass a member function of class A to class B via a function pointer as argument. Please advise whether this road is leading somewhere and help me fill the pothole. #include <iostream> using namespace std; class A{ public: int dosomeA(int x){ cout<< "doing some A to "<<x <<endl; return(0); } }; class B{ public: B(int (*ptr)(int)){ptr(0);}; }; int main() { A a; int (*APtr)(int)=&A::dosomeA; B b(APtr); return 0; } This brilliant piece of code leaves me with the compiler error: cannot convert int (A::*)(int)' toint (*)(int)' in initialization Firstly I want it to compile. Secondly I don't want dosomeA to be STATIC.

  • typedef to store pointers in C

    - by seriouslion
    The Size of pointer depends on the arch of the machine. So sizeof(int*)=sizeof(int) or sizeof(int*)=sizeof(long int) I want to have a custom data type which is either int or long int depending on the size of pointer. I tried to use macro #if, but the condition for macros does not allow sizeof operator. Also when using if-else, typedef is limited to the scope of if. if((sizeof(int)==sizeof(int *)){ typedef int ptrtype; } else{ typedef long int ptrtype; } //ptrtype not avialble here Is there any way to define ptrtype globally?

  • Struct like objects in Java

    - by cdv
    Is it completely against the Java way to create struct like objects? class SomeData1 { public int x; public int y; } I can see a class with accessors and mutators being more Java like. class SomeData2 { int getX(); void setX(int x); int getY(); void setY(int y); private int x; private int y; } The class from the first example is notationally convenient. // a function in a class public int f(SomeData1 d) { return (3 * d.x) / d.y; } This is not as convenient. // a function in a class public int f(SomeData2 d) { return (3 * d.getX()) / d.getY(); }

    I'm trying to describe a Sudoku Board in C++ with a union statement: union Board { int board[9][9]; int sec1[3][3]; int sec2[3][3]; int sec3[3][3]; int sec4[3][3]; int sec5[3][3]; int sec6[3][3]; int sec7[3][3]; int sec8[3][3]; int sec9[3][3]; } Would each section of the board correspond with the correct part of the array? IE, Would sec4 correspond with board[4-6][0-3]? Is there a better way to do this sort of thing (specifically describing a sudoku board)?

  • Why in C++ do we use DWORD rather than unsigned int?

    - by byte
    I'm not afraid to admit that I'm somewhat of a C++ newbie, so this might seem like a silly question but.... I see DWORD used all over the place in code examples. When I look up what a DWORD truly means, its apparently just an unsigned int (0 to 4,294,967,295). So my question then is, why do we have DWORD? What does it give us that the integral type 'unsigned int' does not? Does it have something to do with portability and machine differences?

  • Sort vector<int>(n) in O(n) time using O(m) space?

    - by Adam
    I have a vector<unsigned int> vec of size n. Each element in vec is in the range [0, m], no duplicates, and I want to sort vec. Is it possible to do better than O(n log n) time if you're allowed to use O(m) space? In the average case m is much larger than n, in the worst case m == n. Ideally I want something O(n). I get the feeling that there's a bucket sort-ish way to do this: unsigned int aux[m]; aux[vec[i]] = i; Somehow extract the permutation and permute vec. I'm stuck on how to do 3. In my application m is on the order of 16k. However this sort is in the inner loops and accounts for a significant portion of my runtime.

  • Looking for some help working with premultiplied alpha

    - by user315142
    I am trying to update a source image with the contents of multiple destination images. From what I can tell using premultiplied alpha is the way to go with this, but I think I am doing something wrong (function below). the image I am starting with is initialized with all ARGB values set to 0. When I run the function once the resulting image looks great, but when I start compositing on any others all the pixels that have alpha information get really messed up. Does anyone know if I am doing something glaringly wrong or if there is something extra I need to do to modify the color values? void CompositeImage(unsigned char *src, unsigned char *dest, int srcW, int srcH){ int w = srcW; int h = srcH; int px0; int px1; int px2; int px3; int inverseAlpha; int r; int g; int b; int a; int y; int x; for (y = 0; y < h; y++) { for (x= 0; x< w*4; x+=4) { // pixel number px0 = (y*w*4) + x; px1 = (y*w*4) + (x+1); px2 = (y*w*4) + (x+2); px3 = (y*w*4) + (x+3); inverseAlpha = 1 - src[px3]; // create new values r = src[px0] + inverseAlpha * dest[px0]; g = src[px1] + inverseAlpha * dest[px1]; b = src[px2] + inverseAlpha * dest[px2]; a = src[px3] + inverseAlpha * dest[px3]; // update destination image dest[px0] = r; dest[px1] = g; dest[px2] = b; dest[px3] = a; } } }

  • SQL SERVER – Server Side Paging in SQL Server 2011 Performance Comparison

    - by pinaldave
    Earlier, I have written about SQL SERVER – Server Side Paging in SQL Server 2011 – A Better Alternative. I got many emails asking for performance analysis of paging. Here is the quick analysis of it. The real challenge of paging is all the unnecessary IO reads from the database. Network traffic was one of the reasons why paging has become a very expensive operation. I have seen many legacy applications where a complete resultset is brought back to the application and paging has been done. As what you have read earlier, SQL Server 2011 offers a better alternative to an age-old solution. This article has been divided into two parts: Test 1: Performance Comparison of the Two Different Pages on SQL Server 2011 Method In this test, we will analyze the performance of the two different pages where one is at the beginning of the table and the other one is at its end. Test 2: Performance Comparison of the Two Different Pages Using CTE (Earlier Solution from SQL Server 2005/2008) and the New Method of SQL Server 2011 We will explore this in the next article. This article will tackle test 1 first. Test 1: Retrieving Page from two different locations of the table. Run the following T-SQL Script and compare the performance. SET STATISTICS IO ON; USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 5 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 12100 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO You will notice that when we are reading the page from the beginning of the table, the database pages read are much lower than when the page is read from the end of the table. This is very interesting as when the the OFFSET changes, PAGE IO is increased or decreased. In the normal case of the search engine, people usually read it from the first few pages, which means that IO will be increased as we go further in the higher parts of navigation. I am really impressed because using the new method of SQL Server 2011,  PAGE IO will be much lower when the first few pages are searched in the navigation. Test 2: Retrieving Page from two different locations of the table and comparing to earlier versions. In this test, we will compare the queries of the Test 1 with the earlier solution via Common Table Expression (CTE) which we utilized in SQL Server 2005 and SQL Server 2008. Test 2 A : Page early in the table -- Test with pages early in table USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 5 ;WITH CTE_SalesOrderDetail AS ( SELECT *, ROW_NUMBER() OVER( ORDER BY SalesOrderDetailID) AS RowNumber FROM Sales.SalesOrderDetail PC) SELECT * FROM CTE_SalesOrderDetail WHERE RowNumber >= @PageNumber*@RowsPerPage+1 AND RowNumber <= (@PageNumber+1)*@RowsPerPage ORDER BY SalesOrderDetailID GO SET STATISTICS IO ON; USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 5 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO Test 2 B : Page later in the table -- Test with pages later in table USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 12100 ;WITH CTE_SalesOrderDetail AS ( SELECT *, ROW_NUMBER() OVER( ORDER BY SalesOrderDetailID) AS RowNumber FROM Sales.SalesOrderDetail PC) SELECT * FROM CTE_SalesOrderDetail WHERE RowNumber >= @PageNumber*@RowsPerPage+1 AND RowNumber <= (@PageNumber+1)*@RowsPerPage ORDER BY SalesOrderDetailID GO SET STATISTICS IO ON; USE AdventureWorks2008R2 GO DECLARE @RowsPerPage INT = 10, @PageNumber INT = 12100 SELECT * FROM Sales.SalesOrderDetail ORDER BY SalesOrderDetailID OFFSET @PageNumber*@RowsPerPage ROWS FETCH NEXT 10 ROWS ONLY GO From the resultset, it is very clear that in the earlier case, the pages read in the solution are always much higher than the new technique introduced in SQL Server 2011 even if we don’t retrieve all the data to the screen. If you carefully look at both the comparisons, the PAGE IO is much lesser in the case of the new technique introduced in SQL Server 2011 when we read the page from the beginning of the table and when we read it from the end. I consider this as a big improvement as paging is one of the most used features for the most part of the application. The solution introduced in SQL Server 2011 is very elegant because it also improves the performance of the query and, at large, the database.

  • Need help revolving a 2D array

    Pretty much all I'm trying to do is revolve my 2D Array by its container. I'm using this array for a background and I seem to be having problems with it revolving. public class TileTransformer : GridConstants { public Tile[,] Tiles; ContentManager Content; public TileTransformer(ContentManager content) { Content = content; } public Tile[,] Wraping(Tile[,] tiles,Point shift) { Tiles = tiles; for (int x = shift.X; x < 0; x++)//Left shift { for (int X = 0; X < GridWidth; X++) { for (int Y = 0; Y < GridHeight; Y++) { if (X + 1 >GridWidth-1) { Tiles[0, Y].Container =tiles[X, Y].Container; } else { Tiles[X+1, Y].Container =tiles[X, Y].Container; } } } } for (int x = shift.X; x > 0; x--)//right shift { for (int X = 0; X < GridWidth; X++) { for (int Y = 0; Y< GridHeight; Y++) { if (X-1==-1) { Tiles[GridWidth-1, Y].Container =tiles[0, Y].Container; } else { Tiles[X - 1, Y].Container =tiles[X, Y].Container; } } } } for (int y = shift.Y; y > 0; y--)//shift up { for (int X = 0; X < GridWidth; X++) { for (int Y = 0; Y < GridHeight; Y++) { if (Y - 1 == -1) { Tiles[X, GridHeight-1].Container = tiles[X, Y].Container; } else { Tiles[X, Y - 1].Container = tiles[X, Y].Container; } } } } for (int y = shift.Y; y < 0; y++)//shift down { for (int X = 0; X < GridWidth; X++) { for (int Y = 0; Y < GridHeight; Y++) { if (Y + 1 == GridHeight) { Tiles[X, 0].Container = tiles[X, Y].Container; } else { Tiles[X, Y + 1].Container = tiles[X, Y].Container; } } } } return Tiles; } Now the Problems that I'm having is either when I shift up or left it seems the whole array is cleared back to the default state. Also when I'm revolving the array it appears to stretch it upon the sides of the screen that it is shifting towards.

    Here is the UnityScript implementation of the method i use to generate a randomly tiled background, the problem i'm having relates to how to translate the call to the newTile method in c#, so far i've had no luck fiddling... can anyone point me in the correct direction? Thanks #pragma strict import System.Collections.Generic; var mapSizeX : int; var mapSizeY : int; var xOffset : float; var yOffset : float; var tilePrefab : GameObject; var tilePrefab2 : GameObject; var tiles : List.<Transform> = new List.<Transform>(); function Start () { var i : int = 0; var xIndex : int = 0; var yIndex : int = 0; xOffset = 2.69; yOffset = -1.97; while(yIndex < mapSizeY){ xIndex = 0; while(xIndex < mapSizeX){ var z = Random.Range(0, 5); if (z > 2) { var newTile : GameObject = Instantiate (tilePrefab, Vector3(xIndex*0.64 - (xOffset * (mapSizeX/10)), yIndex*-0.64 - (yOffset * (mapSizeY/10)), 0), Quaternion.identity); tiles.Add(newTile.transform); newTile.transform.parent = transform; newTile.transform.name = "tile_"+i; i++; xIndex++; } if (z < 2) { var newTile2 : GameObject = Instantiate (tilePrefab2, Vector3(xIndex*0.64 - (xOffset * (mapSizeX/10)), yIndex*-0.64 - (yOffset * (mapSizeY/10)), 0), Quaternion.identity); tiles.Add(newTile2.transform); newTile2.transform.parent = transform; newTile2.transform.name = "Ztile_"+i; i++; xIndex++; } } yIndex++; } } C# Version [Fixed] using UnityEngine; using System.Collections; public class LevelGen : MonoBehaviour { public int mapSizeX; public int mapSizeY; public float xOffset; public float yOffset; public GameObject tilePrefab; public GameObject tilePrefab2; int i; public System.Collections.Generic.List<Transform> tiles = new System.Collections.Generic.List<Transform>(); // Use this for initialization void Start () { int i = 0; int xIndex = 0; int yIndex = 0; xOffset = 1.58f; yOffset = -1.156f; while (yIndex < mapSizeY) { xIndex = 0; while(xIndex < mapSizeX) { int z = Random.Range(0, 5); if (z > 5) { GameObject newTile = (GameObject)Instantiate(tilePrefab, new Vector3(xIndex*0.64f - (xOffset * (mapSizeX/10.0f)), yIndex*-0.64f - (yOffset * (mapSizeY/10.0f)), 0), Quaternion.identity); tiles.Add(newTile.transform); newTile.transform.parent = transform; newTile.transform.name = "tile_"+i; i++; xIndex++; } if (z < 5) { GameObject newTile2 = (GameObject)Instantiate(tilePrefab, new Vector3(xIndex*0.64f - (xOffset * (mapSizeX/10.0f)), yIndex*-0.64f - (yOffset * (mapSizeY/10.0f)), 0), Quaternion.identity); tiles.Add(newTile2.transform); newTile2.transform.parent = transform; newTile2.transform.name = "tile2_"+i; i++; xIndex++; } } yIndex++; } } // Update is called once per frame void Update () { } }
