Hello,
I have been trying to get the following code to work, but unfortunately
without any succes so far. I have searched in newsgroups and google but
found nothing there that could solve my problem.
Given the following classes :
template <class T>
class AAA{
int tabel[5];
public:
T &getItem(int i){
return tabel[i];
}
};
template <class T>
class A{
public:
AAA<T t;
T &operator[](int index) {
return t.getItem(index );
}
};
class B : public A<int{
public:
void Bfun(){
t[0]=4;
}
};
My gcc compiler comes with the following error:
main.cc27 : error: no match for 'operator[]' in
'((B*)this)->B::<anonymous> .A<int>::t[0]'
Is there anybody who could give me a hint in the right direction? I
tried nonmember functions (for the operator) but the compiler says that
operator[] should be a nonstatic member function.
Thanks in advance,
Joachim 2 1524

That's because AAA lacks an operator[]. try something like:
template <class T>
class AAA{
int tabel[5];
public:
T &getItem(int i){
return tabel[i];
}
int& operator[]( unsigned n ) { return tabel[5]; }
};

Hello all,
I'm trying to get a grasp of the difference between specializing a function
template and overloading it. The example below has a primary template, a
specialization and an overload. Note that the overload is identical to the
specialization except, of course, for the missing "template <>".
I don't know if my questions will be a bit too broad or not, but I thought
I'd give it shot... When is overloading preferable to...

Hello,
recently I wrote a little class which has to wrap two different type of
data, showing the same external interface.
I used operator overloading, but the same result I could eventually
obtain with two classes derived from an abstract base class containing
only the interface functions. So, when it's worth to use overloading
mechanism instead of abstract/inherited?

I am getting a compiler error that I can't well explain or even
understand the origin of (though I boiled it down close...). Below is
a bare-bones example.
What I am doing is defining the increment operator in a class and then
defining a derived class and using the derived class. When I try to
use the increment operator on an instance of the derived class (as an
instance of the derived class, not when used as an instance of the base...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
