C# :: Clear White Space On Random Tile Map
Mar 14, 2015I've got myself a 2d array
int[,] map = new int[100,100];
I've populate that will a bunch of 1's and 0's. The 1 represents a wall, and a 0 is dirt.
I'm looking for a way to clean up my blank spaces outside of my walls. Any algorithm I can use to identify these big areas and replace them with a '1'
for (int y = 1; y < map.GetLength(1) - 1; y++) {
for (int x = 1; x < map.GetLength(0) - 1; x++) {
// Inside here is where I was hoping to archive my work
bool draw = true;
foreach (Room room in rooms)
[Code] ....
Attached is an example of my output.As you will be able to see, there is a lot of brown. I want to fill the brown with walls, but leave space for a path between the rooms.The 'draw' bool is true when I'm outside of a room, just so I don't start throwing walls inside my room.
Example of what the array would look like (for those who don't know)
int[,] map = new int[100,100]
{
{0,1,1,1,1,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,0,0,0,1,0},
{0,1,1,1,1,1,0},
};
C++ :: Sort Ascending Random Numbers - Vectors
Oct 21, 2013I'm trying to sort random numbers in ascending order and I was wondering how I should go about that.
Here's what I currently have.
#include <iostream>
#include <vector>
#include <cstdlib>
using namespace std;
[Code].....
I'm trying to put our algorithm between the ////'s. We're only allowed to use for loops also. What I currently have is the minimum number finder and the use of temp to find the values. However, it doesn't seem to be working.
C++ :: Create Two Vectors With 10 Elements And Input Random Numbers
Feb 9, 2014I can't compile this code as I am at work and the computers are security protected, So i''l have to wait until i get home to test this, but I am pretty sure I am wrong. The problem is I have to create two vectors with 10 elements and input random numbers into it, then pick one of the elements of the second vector at random and append it to an element from the first vector at random. This has to be done 10 times and the I am assuming i have to print the 10 results. This is what I have:
#include <cstdlib>
#include <ctime>
#include <iostream>
using namespace std;
int main() {
vector<int> random (10);

C++ :: List Of Vectors (vector Of N Vectors Of M Elements)
Mar 19, 2014I create a list of vectors (a vector of n vectors of m elements).
std::vector <std::vector <int> > vsFA (n, std::vector<int>(n));
How I assign values? I try below, but not worked
void armazenaFA( std::vector <int> &vFA) // this function only knows about vFA
{ vsFA[n] [m]= simTime().dbl();
OR
vsFA[n].push_back(simTime().dbl());
}
C++ :: Create Two Vectors And Then Loop Through The Vectors
Sep 19, 2014This is probably a very basic question, but I need to create two vectors and then loop through the vectors and output each pair that is found.
The user will input min1 and max1 with step1 for the first vector and min2 and max2 and step2 for the second vector. Then the loops will go through and return the combinations will return each pair of the two vectors.
So if I input min1=1 and max1=10 and step1=1 and same for vector two the return would be:
[1,1]
[1,2]
.
.
.
[10,10]
This is for part of a homework assignment, but I can't continue on the assignment without first getting this simple part to work.
C++ :: Concatenate Two 2-dimensional Int Arrays Into One Larger 3-dimensional Array
Jul 31, 2013How can I concatenate two 2-dimensional int arrays into one larger 3-dimensional array. This question is also valid for the 3-dimensional vectors. I know the command for the one dimensional vector as:
std::vector<int> results;
results.reserve(arr1.size() + arr2.size());
results.insert(results.end(), arr1.begin(), arr1.end());
results.insert(results.end(), arr2.begin(), arr2.end());
and for the one dimensional array as:
int * result = new int[size1 + size2];
copy(arr1, arr1 + size1, result);
copy(arr2, arr2 + size2, result + size1);
But I do not know how to make a 3-dimensional array or vector.
C :: Assigning A Structure As A Unit
Feb 21, 2014I am reading the book C Programming Language. On Structures, it says:
"The only legal operations on a structure are copying it or assigning to it as a unit, taking its address with &, and accessing its members."
What does it mean assigning a structure as a unit?

Mar 13, 2015I am currently trying to send a x264 nal unit using WINSOCK with a reliable multicast socket. It isn't decoding properly, and my initial thought is I am not receiving all the bytes correctly. I was hoping some fresh eyes can provide insight on errors or any improvements. I have seen some topics about this subject, and they showed sending entire structs with the socket. However, I am concerned about endianess so I am trying to stay away from that approach. I have commented out the decoding part, until I am confident that I am receiving the nal unit properly.
Server:
#include <WinSock2.h>
#include <WS2tcpip.h>
#include "wsrm.h"

C# :: Unit Of Work And Repository Pattern
Oct 18, 2014I have implemented the IRepository and UnitOfWork Patterns in my project and I have made a little tweak in the UnitOfWork pattern .
public class UnitOfWork : IDisposable {
private DataContext m_Context = new DataContext();
private bool m_disposed = false;
#region Repositories
private GenericRepository<Product> m_ProductRepository = null;
private List<object> m_RepositoryList = new List<object>();
#endregion
[Code] ....
In my UOW class I have the public property ProductRepository. Now my idea was instead of creating a public property for every repository that I have, I created the generic method GetRepository<T> to dynamically create repositories.
Do you think that this change will have bad side effects. I think that it will improve the maintainability of the code.
C++ :: Running Unit Test On Library - Checking For NAN?
Jan 31, 2012I am running a unit test on a library and this line keeps failing on Fedora 16, G++ 4.6.2
Code:
assertNAN(double, std::numeric_limits<double>::signaling_NaN()); //sanity check
The assert looks like this
Code:
//needs to copy it so that if its a function call it only does it once
#define assertNAN(type, one) {
type val = (type)one;
std::string lag(#one);
lag += " not a number";
[Code] ...
I am compiling with -DNDEBUG -O3 -ffast-math -fexpensive-optimizations to simulate a production environment. Is there a way to test for NAN consistently?
C++ :: Converting One-dimensional To Two-dimensional Array
Jan 17, 2014I had a hard question in my C++ final exam and I'm trying to solve it for the last 3 days. I haven't succeded yet! Here is the question: You have a one-dimensional array A[20]={1,2,3,4,...,20} and B[5][4] you have to assign the A array's elements to the B array but there is an order which is: B[5][4] = { { 12, 9, 11, 10 }, { 14, 7, 13, 8 }, { 16, 5, 15, 6 }, { 18, 3, 17, 4 }, { 20, 1, 19, 2 } } and there is a restriction: you can only use ONE for statement, nothing else!
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
int A[20] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,
16, 17, 18, 19, 20 }; // define A array's elements.
int B[5][4] = { 0 }, k = 1; // define B array and k counter.
[code]....
I can't narrow the statements to one,This program works perfectly but it shouldn't be that long, we need ONLY ONE FOR statement, not two!
C# :: Breaking Dependency In Static Method For Unit Test?
Feb 6, 2014I have function that returns historical data. I can access it, using file name. If I use file name, it reads that file and saves it to dictionary, so that in the future, if historical data is required for the same file, it does not read it again (it's lazy loading). If no file is supplied to the function, it tries to read file which is given in app settings.
However, for unit testing, I do not want to read any file. Instead, I want it to use small sample of hardcoded historical data. In order to do that, I think, I need to introduce interface to it. Then I can use some IoC to choose between different implementation for unit testing purpose and ordinary launch of application.
Function to get history is given as follows:
public static class Auxiliary
{
private static Dictionary<string, MyData> _myData;
public static MyData GetData(string fileName = null)
{
// ...
}
}
I have created default Unit Test project with Visual Studio so, as far as I know, by default it uses MSTest as test runner and MSUnit as unit testing framework but it does not have any IoC container so I should manage NuGet packages for solution and install Unity.
As far as I know, MSUnit (aka Moles) can unit test static methods (it's unconstrained isolation framework, like Typemock Isolator, unlike NUnit) but still many people suggest not to use any static methods for unit testing.
Should I use shim or stub [URL] Stubs should be used for faking external dependencies and here it is not external library, but my own code.
C++ :: How To Write Boost Unit Test In Visual Studio 2010
Apr 16, 2014I'm new to c++ and boost library also. I need to test a function of my library. For example
// Functions.hpp

//Functions.cpp
int add(const int x, const int y)
{
return (x + y);
}
Now i need to test add function using boost. I need the result or output in below style. What all settings do i need to do in VS 2010 and how i should include boost test in the project.

C++ :: Write Unit Convertor For Converting Temperatures Celsius / Kelvin And Fahrenheit
Feb 8, 2014I am trying to write a unit convertor for converting temperatures Celsius, Kelvin and Fahrenheit.
Code:
if (select_one == 't' || select_one == 'T'){// this one works perfectly...
//This section does not tell you the use of variables.
//The use of variables can be seen as comments in the main program
[Code].....
This part of code will be part of a larger Unit Converter program. Do you think this method of conversion is wise? The error codes are for debugging use only.
I convert all temperatures of all units, whether Celsius, Kelvin or Farhenheit into Celsius and then convert it into the units the user wants.
For example:
Kelvin -----> Celsius ------------------> Farhenheit
(Input) (base of conversion) (desired output unit)
Do you think this type of conversion is okay?

C :: How To Copy 3 Dimensional Array Into 2 Dimensional Array
Sep 2, 2013I have a 3D array that contains 200 strings. I'm trying to copy all these strings into a 2D array. How can this be done? This is what I have so far but it isn't working correctly.
Code:
for(int i = 0; i < row; i++) {
for (int j = 0; j < col; j++)
{
dest[i][j] = source[0][i][j];
} }
The finished product would be with 100 rows, 2 columns.
