C/C++ :: Time Difference Returned In Seconds
Mar 6, 2015I need to get the current time, have the system sleep for a period of time, then return the difference in seconds.
#include <iostream>
#include <string>
#include <ctime>
#include <time.h>
#define _CRT_SECURE_NO_WARNINGS
using namespace::std;
// in the <ctime> library is a function time(0)
[Code] ....
I'm not receiving an errors but the return value is not correct. It's returning 1.4259 no matter how long it sleeps for.
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.

Jan 31, 2012I am running a unit test on a library and this line keeps failing on Fedora 16, G++ 4.6.2
Code:

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++ :: Error With Value Being Returned
Nov 18, 2013I am working on my final project for my class and after finally getting it to compile with no errors to finding examples/tutorials and following skeleton code I cam encountering a problem.
The program runs, asks all the correct questions but when it displays the base pay and total pay for all 3 employees it comes back as ( -1.0743 blah blah )
When they work over 40 hours it works correctly but when they work under 40 hours it displays those weird numbers in those sections.

C++ :: Why Can't Void Be Returned
Apr 22, 2012Why is it not okay to return void? Most compilers will probably let you (gcc does) but it gives you a warning that you aren't supposed to. Most languages allow you to return void.
Something like
Code:
void log(const std::string & txt){ std::cout << txt << std::endl; }
//C++ way to do it
void bar(int i){

C :: Same Error Returned For All Code

C/C++ :: Indices Returned In Bsearch
Jul 14, 2014I have some struct which contains: void *elems (basically a pointer to an array of contiguous memory).
I want to use bsearch to return a pointer, and then somehow figure out where in the array that value is. Having a pointer in this case isn't enough, I need to know what the index is. I've tried a number of things:
int index;
void *value = bsearch(key, start_ptr, cv->count, cv->elemsz, cmp);
index = &value - &start_ptr;
return index; [
Replacing the second line with:
// in the first instance
index = (char*) value - (char*) start_ptr;
// in other instances...
index = ((char*) value - start_ptr))/cv->elemsz)
But nothing works.
C :: How To Save Returned Of Unknown Length
Sep 15, 2014I call a function that returns a string, and I can print it out fine, but I want to test the result of the function to see if it returns 0. But I can't just call the function again (GetNextToken(b)) because it will generate a different token. I can't allocate space for the string because I'm not sure what the size of the returned string is going to be.
Basically I want to see if the GetNextToken(b) returns 0, and if it doesn't then print the string. And running GetNextToken(b) again will give a different result.
Code:
int main(int argc, char **argv) {
SomeStruct* b = CreateStruct(argv[1],argv[2]);
printf("HERE %s", GetNextToken(b));
C :: How To Get Address Returned By Malloc Function
Dec 6, 2013So, I'm in the midst of implementing my own malloc() and free() functions, but I'm having a hard time with the syntax of getting the address that malloc returns. Whenever I check the address, it's 0 Here's the code:
Code:
char *word = malloc(10);
int address = *word;
printf("%d",address);
The reason I want the address is so that I could store it in a data structure for further usage when I'm dealing with different cases for the free() function. Or is there another way to do this?
C++ :: Returned Temporal Objects Lifetime
May 4, 2014What does the C++ standard say about returned temporal objetcts's lifetime ?For example, in this code:
#include <iostream>// Object cout, manipulator endl
using std::cout;
using std::endl;
class C {
private:
[code]....
Here, the temporal object C returned by function f() still lives when function h() is called and is destroyed inmediately after function h() returns to his caller (the function main()). So, it seems that a returned temporal object lives while it is used and it is destroyed when not used (in the next sentence of the sentence that call the function that returns the temporal object). Does the C++ standard specify that this must be the behaviour of C++ compilers?

C/C++ :: Store Returned Array From A Function
Feb 12, 2014I am just trying to make a simple two player game. First player enters the movie and second player guesses it by using some basics of C++.
movie[] = entered by player 1.
movie_temp[]= a temp array with '_' in it. It updates after every guess by player 2.
MY PROBLEM: Please refer the main function where I called the function movie_check().
This updates the life after every guess. I want the same to happen for my movie_temp array.
When i run this program, only the lives are updated properly, on correct guess the lives are not reduced, but in next turn the array_temp is not updated and the same array is displayed again and again after each gas.
How to create a function which return array and save it in movie_temp (just as I did for life).
IDE: Code::Blocks
Compiler: GCC Compiler
#include<iostream.h>
#include<stdlib.h>
#include<ctype.h>
#include<string.h>
#include<conio.h>
void display_movie(char movie_temp[], int);
void display_life(int);
