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?
I 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.
I'm new to c++ and boost library also. I need to test a function of my library. For example
// Functions.hpp int add(const int x, const int y); //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.

I have created a shared object in Ubuntu (libMYLIB.so). I am now trying to compile a simple test program (testmylib.c) to see if the shared object is properly built. I am getting an error that the build cannot find the shared object. My build command is:
I 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.
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.
I 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.
I've been reading about libraries; How to make them, how to use them, the different types of libraries, etc..
When using a shared library, does the program require that library to be installed on the computer after the program has been compiled into an .exe?
Ie.. if somebody downloaded a "Helloworld.exe" that I had compiled on my computer using a shared library (that wasn't part of a standard operating system), would they also need that shared library on their computer for the program to run without errors?
and for Static Libraries, when I compile a program using a static library, does it include in the final binary only the functions of the library that are actually used, or does the compiler add in the entire library?
I need to sort this and I know how to do it. But I need to sort it again with the highest value in the first row and keep all information in that row paired with the name . So
Lincoln 120 300 400 Parks 100 500 250
Parks 100 500 250 Lincoln 120 300 400
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?
Q. In context of C language syntax checking, which of the following can be modeled using Finite Automata?
(A) Detecting proper termination of an instruction. (B) Detecting balance of parentheses. (C) Detecting initialization of a variable. (D) None of the above.
I think I may have found a new way of checking for 3d polygon collisions, but I'm not sure. The method involves...
1. finding the planes that the primitives lie on 2. finding the line where the planes intersect 3. if both polys have points on both sides of the line AND have points that overlap on the 1d space of the line, then they intersect.
I have some half done code testing this, and so far it seems to be sound and fairly fast. These are some average time-tests done on my machine for each part:
The above code would proceed to create a new array, store it in a pointer and retrieve the memory address of the array before finally deleting the array.
So let's assume we re-build the pointer and try to access the now deallocated array:
Pointer = ( uint32* ) MemAddr; Pointer[ 0 ] = 0;
Based on the above snippets of code, how would I check "Pointer" after rebuilding the memory to check if the rebuilt memory has actually been deallocated. Without a check we'd get an exception error.
A bit of detail on why I am trying this:
Before thinking up how to do this, I was storing the addresses in a list and check the list for the addresses to see if they existed or not. However this requires an O(n) search, which isn't exactly what I am wanting. So instead if I used a check for deallocation method, I can go for an O(1) time check and reduce the total time it would take to check for memory allocation/deallocation.
I have created a prompt which prompts the user for an integer and I have set up a loop to check for if it is an integer or not. My "bug" is that a user can enter an "integer" and "space" and "enter" and it does not give any error and assumes that "All is FINE!". I have gotten the value from the ascii table of 'SPACE' and put it as a check in my parameter of while, but it does not work.
Here is my code:
int x, y, boolean, i; char buff[256]; printf("Enter the first integer value: "); scanf("%s", buff); i = 0; boolean = 0; //initializing our boolean var that will eventually decide if we have an error or not
template <typename T> class Matrix { // some stuff and some methods };
and let's say that you have some methods that need to do some type-dependent stuff, like, for example,
template <typename T> Matrix<T> Matrix<T>::transpose() const { // get this->rowCount, this->columnCount // create a Matrix that has rowCount amount of columns and columnCount amount of rows // copy (*this)[j][k] to theMatrix[k][j] (for all of the entries in *this) // if the entries are complex, take the complex conjugate of them all }
Would it be good practice to check explicitly for the typename parameter (or is this, somehow, defeating the purpose of templates)? std::cout << "I know that this is a design question, but it needs to be asked... ";
I'm playing around with parts of code and am coming across some errors. Most of my concern is related to strtok(). I've used it before but with a char* named token. I used a while loop to continuously check whether token was equal to NULL. In the following code, however, there aren't any checks. I was wondering if that is why this code prints (null) while running. Also, I would like to know if it is possible to read input like this code attempts to do - assigning tokens to each variable one after the other.
Assuming I have a list of pointers to a generic type T:
#include <vector> //... list<T*> myList;
Now assuming I want to go on the list, and if T's type is matched to the type I'm looking for, then cast it to this type and do something. List shown here:
