C++ is the most commonly used language in introductory and intermediate programming courses in Bulgarian universities. In recent years this language has developed greatly. Its abstractions are more flexible and affordable than ever before. Such great number of changes are related to the launch of the new standard (known as C++11) that we have grounds to consider it even a new language. It is in...

Let Ω ⊂ R, n ≥ 2, be a bounded domain with smooth boundary. Consider utt −4xu+ q(x, t)u = 0 in Ω× [0, T ] u(x, 0) = 0, ut(x, 0) = 0 if x ∈ Ω u(x, t) = f(x, t) on ∂Ω× [0, T ] We show that if u and f are known on ∂Ω× [0, T ], for all f ∈ C∞ 0 (∂Ω× [0, T ]), then q(x, t) may be reconstructed on C = { (x, t) : x∈Ω, 0 < t < T, x− tω & x+ (T − t)ω 6∈ Ω ∀ ω ∈ R, |ω| = 1 } provided q is known at all po...

This paper proposes to augment C++11’s TransformationTraits with a number of template aliases whose use dramatically simplifies the traits’ most common applications.

We describe how legacy C++ programs can be rejuvenated using C++11 features such as generalized constant expressions, perfect forwarding, and lambda expressions. In general, this work develops a correspondence between different kinds of macros and the C++ declarations to which they should be transformed. We have created a set of demacrofication tools to assist a developer in the rejuvenation of...

A number of years ago, [Bro05] explored a prospective language feature then known as Object Templates. That feature died on the vine due to healthy skepticism voiced by EWG, as well as the usual lack of cycles to develop the idea much further. However, the original underlying issue is still present in C++11, after even many additional years of experimental effort to achieve the desired effect v...

C++ is the most commonly used language in introductory and intermediate programming courses in many universities. This language had its rapid development in recent years. Its abstractions are more flexible and affordable than ever before. There are so many new features in the new standard, known as C++11, that it may be considered a new language. All these changes should find their place in tea...
