Hi,
My question is how to resolve in C# ambiguous overloaded operators?
Let say, I have two unrelated classes A and B, each one implements
overloaded operator + with the first parameter of type A, and the
second one of type B. Let say, these are not my classes and I know
nothing about the implementation. As system doesn't know what code
must be used for resolving the language construction a+b (where A a;
and B b;), it returns "The call...

Hi,
Maybe somebody has been fighting with the problem that I do, currently.
I have a class that has method f(). The two versions of the f() method
accept different objects: Int and Short. These objects have
constructors that allow implicit conversions from simple types. All
this has been defined as follows:
<code>

Hi,
I'm trying to extend an STL class with additional iterator
functionality. In the simplified example below I added an extra
iterator class with a dereferencing operator. This operator
internally relies on the at function of the superclass.

hiya, i'm having this weird error on my project. As far as I know "ambiguous call to overloaded function" should only occur when the compiler must choose from several methods, but here i don't think it's the case. I've got the following class:
class item
{
public:
item(string id_,string datatype_);
//item(string id_,string datatype_,int periodo_);
//item(string id_,string datatype_,string headerfile_);
//item(string id_, string...

I have a templated class with the following methods:
Vocab(const T& t);
Vocab(unsigned uid);
However, when T = unsigned, and I call Vocab(unsigned(0)) then the
compiler rightly complains about an ambiguous call to the overloaded
function.
How can I specify which method I want called in this case?
Thanks,

I want to overload function to swap two others types, for example,
type<T>, T* and so on,
but I can't compile the following code at VC 6.0.
The compiler says :

I'm writing a String class for C++ and I'm getting the following error

Could someone please tell me what is wrong with the following -ugly-
piece of c++ code. Why when I explicititely set the template parameter
my gcc compiler start getting confused:
bla.cxx: In function 'int main()':
bla.cxx:25: error: call of overloaded 'foo(short unsigned int*&)' is
ambiguous
bla.cxx:2: note: candidates are: void foo(OutputType*)

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
