override and final

By using the context sensitive keyword override and final you can explicit manage the overriding of virtual functions. In particular, the keyword override solves a lot of issues with difficult to finding bugs in object hierarchies: Methods that should override methods of base classes. The result is a syntactically but not semantically correct program. The program performs the wrong stuff in the right way.

Raw and Cooked

C++11 has user-defined literals for characters, C strings, integers and floating point numbers. For integers and floating point numbers they are available in raw and cooked form. Thanks to C++14 we have built-in literals for binary numbers, C++ strings, complex numbers, and time units.

Check Types

Template Metaprogramming is programming at compile time. But what has template metaprogramming in common with the type-traits library? A lot! The type-traits library is pure template metaprogramming, tamed in a library. With this post my presentation of the type-traits library becomes more structured.

More and More Save

In the post Statically checked I wrote that the functions of the type-traits library are an ideal fit for static_assert. The reason is that static_assert requires a constant expression. The functions of the type-traits library provides a lot of checks which can be performed at compile time. With this posts I will prove my statement.

The initialization of variables was uniformed in C++11. The rule is quite simple. {}-Initialization is always applicable.

auto-matically inititialized

Probably the most frequently used feature of C++11 is auto. Thanks to auto the compiler determines the type of a variable from its initializer. But what is the point with safety critical software?
