Default attribute in base class precludes delegation

by: Gabriel Genellina | last post by:

Hi In the following code sample, I have: - a Worker class, which could have a lot of methods and attributes. In particular, it has a 'bar' attribute. This class can be modified as needed. - a Base class (old-style) which defines a default class attribute 'bar' too. I can't modify the source code of this class. Note that Workes does not inherit from Base. - a Derived class which must inherit from Base and is a wrapper around Worker: it...

Hi, I'm learning C++ as a hobby using The C++ Programming Language : Special Edition by Bjarne Stroustrup. I'm working on chpater 13 exercises that deal with templates. Exercise 13.9 asks for me to turn a previously made String class that deals with char's into a templated String class that uses the template parameter C instead of char.

access public function of derived class through base class pointer

by: Banaticus Bart | last post by:

I wrote an abstract base class from which I've derived a few other classes. I'd like to create a base class array where each element is an instance of a derived object. I can create a base class pointer which points to an instance of a derived class, but when I pass that base class pointer into a function, it can't access the derived object's public functions. Although, the base class pointer does call the appropriate virtual function...

Old template class works in VC++ Not in C++ Builder 5

by: Hamilton Woods | last post by:

Diehards, I developed a template matrix class back around 1992 using Borland C++ 4.5 (ancestor of C++ Builder) and haven't touched it until a few days ago. I pulled it from the freezer and thawed it out. I built a console app using Microsoft Visual C++ 6 (VC++) and it worked great. Only one line in the header file had to be commented out. I built a console app using Borland C++ Builder 5. The linker complained of references to...

module to implement Abstract Base Class

by: emin.shopper | last post by:

I had a need recently to check if my subclasses properly implemented the desired interface and wished that I could use something like an abstract base class in python. After reading up on metaclass magic, I wrote the following module. It is mainly useful as a light weight tool to help programmers catch mistakes at definition time (e.g., forgetting to implement a method required by the given interface). This is handy when unit tests or...

Problem With Comparison Operator <=> in G++

by: Oralloy | last post by:

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...
