C++: Primitive types

A primitive type is a data type where the values that it can represent have a very simple nature (a number, a character or a truth-value); the primitive types are the most basic building blocks for any programming language and are the base for more complex data types. These are the primitive types available in… Continue reading C++: Primitive types

C++11: Variadic templates (functions)

A very interesting C++0x feature are the "variadic templates" that, in short, are template classes and functions with a variable number of parameterized types. They can be useful to do several things, for example: Provide type-safe replacements for functions with variable number of arguments (stdarg.h) Let the user to create instances of n-tuples. Create type-safe… Continue reading C++11: Variadic templates (functions)

Java: Writing a Windows Forms application using Java

I was playing around with IKVM.NET ( and I found it very very interesting. IKVM.NET is a Java Virtual Machine implemented on top of .NET; and though this is already kind of weird, the most interesting thing is that inside IKVM, the Java objects of your Java application are first class objects of the CLR.… Continue reading Java: Writing a Windows Forms application using Java

C++: The curiously recurring template pattern

Let's consider the following class: This class will be useful as the base class for implementing several specialized writers (a file writer and a console writer come to my mind right now), for instance: Nice, isn't it? We can use the Writer::write() method to write on any kind of media depending on the subclass we… Continue reading C++: The curiously recurring template pattern

C++: Inheritance on template specialization

When you implement something like: You are saying the C++ compiler: "Please, use the first template for all the MyClass<T> instances with any T except for the MyClass<T> instances where T = char". The problem I see with this approach is that you must provide full implementations for the template and for the <char> specialization… Continue reading C++: Inheritance on template specialization
