I'm writing a simulation for class, and part of it involves the reproduction of organisms. My organisms are kept in an array, and I need to increase the size of the array when they reproduce. Because I have multiple classes for multiple organisms, I used a template: template <class orgType> void expandarray(orgType* oldarray, int& numit...

Given two integers X and Y, I want to overwrite bits at position P to P+N. Example: int x = 0xAAAA; // 0b1010101010101010 int y = 0x0C30; // 0b0000110000110000 int result = 0xAC3A; // 0b1010110000111010 Does this procedure have a name? If I have masks, the operation is easy enough: int mask_x = 0xF00F; // 0b1111000000001...

Is it possible to create a template function that takes a variable number of arguments, for example, in this Vector< T, C > class constructor: template < typename T, uint C > Vector< T, C >::Vector( T, ... ) { va_list arg_list; va_start( arg_list, C ); for( uint i = 0; i < C; i++ ) { m_data[ i ] = va_arg( arg_list, T...
Hello this is similar to http://stackoverflow.com/questions/2620165/how-to-access-a-named-element-of-a-derived-user-control-in-silverlight with the difference is inheriting from a templated control, not a user control. I have a templated control called MyBaseControl Xaml:- <Style TargetType="Problemo:MyBaseControl"> <Setter Pr...

I am writing a functor F which takes function of type void (*func)(T) and func's argument arg. template<typename T> void F(void (*func)(T), WhatTypeHere? arg) { func(arg); } Then functor F calls func with arg. I would like F not to copy arg, just to pass it as reference. But then I cannot simply write "void F(void (*func)(T), T&)"...
Hi, I tried to create a custom project template for setting up unit testing. The problem is that when i create a new project based on this template it creates references to the template files : When i edit a file, it changes my template files instead of my actual project files ! When i delete my template, files from my actual project ...
I have a problem with a template and pointers ( I think ). Below is the part of my code: /* ItemCollection.h */ #ifndef ITEMCOLLECTION_H #define ITEMCOLLECTION_H #include <cstddef> using namespace std; template <class T> class ItemCollection { public: // constructor //destructor void insertItem( const ...
I have property in my model which is a collection type (List). I'd like to call for each item in this collection Html.DisplayFor or Html.EditorFor. How can I do this ? EDIT It's not a strong-typed view. It's a templated view. There is only ViewData.ModelMetadata. ...
In a comparison operator: template<class R1, class R2> bool operator==(Manager<R1> m1, Manager<R2> m2) { return m1.internal_field == m2.internal_field; } Is there any way I could enforce that R1 and R2 must have a supertype or subtype relation? That is, I'd like to allow either R1 to be derived from R2, or R2 to be derived from R...
std::map find/end both provides const_iterator and iterator, e.g. iterator end (); const_iterator end () const Out of curiosity,if I have a std::map , which will be called/compared here, an iterator or a const_iterator ? : if(m.find(key) != m.end()) { ... } And should I care ? ...
Hi All, I have a few classes in a project that I inherited that are really old, last I knew they compiled with CodeWarrior 8. I am now in XCode 3.2 Here is an example of what I struggle with: template <class registeredObject> typename std::vector<registeredObject>::iterator FxRegistry<registeredObject>::begin(void) { return mRegi...
A coworker recently showed me some code that he found online. It appears to allow compile time determination of whether a type has an "is a" relationship with another type. I think this is totally awesome, but I have to admit that I'm clueless as to how this actually works. Can anyone explain this to me? template<typename BaseT, typenam...
I was just trying to learn the syntax of the beginner things, and how it worked when I was making this short bit of code in VS2008. The code below works in adding numbers 1 to 499, but if I add 1 to 500, the compiler bugs out giving me: fatal error C1001: An internal error has occurred in the compiler. And I was just wondering why that...
Here, is my code. Just trying to wrap my head around some of the basic things you can do with TMP. I'm trying to supply two numbers with which the compiler will add up that range of numbers. I'm just not sure how to write the syntax for the "constraint" template. template < int b, int e > struct add { enum { sum = add< b + 1, e >::s...
