    Ein Konzept ist ein Begriff, der eine benannte Menge von Anforderungen für einen Typ beschreibt. Konzepte sind ein bequemer Weg, um sowohl anzugeben, welche Eigenschaften von einem Typ zu erwarten sind, als auch welche Eigenschaften ein Typ hat.
    Original:
    A concept is a term that describes a named set of requirements for a type. Concepts are a more convenient way to specify both what properties are expected from a type, and what properties a type has.

    Es gab a proposal eine formale Spezifikation von Konzepten in C++11, mit der Zielsetzung, dass der Compiler die Art der Anforderungen vor der Instanziierung prüfen kann und somit sinnvollere Fehlermeldungen produzieren kann, falls ein Typ die Anforderungen des Templates nicht erfüllt. Dieser Vorschlag wurde später aus verschiedenen Gründen wieder fallen gelassen. Allerdings gibt es inoffizielle Pläne, in einer zukünftigen Version von C++ Konzepte wieder hinzuzufügen.
    Original:
    There was a proposal to include a formal specification of concepts into C++11 so that the compiler could check the type requirements before template instantiation and in turn could produce much more sensible error messages in case a type did not fulfill the template requirements. This proposal was later dropped for various reasons. However, there are unofficial plans to add concepts to a future revision of the C++ language.

    Die hier aufgeführten Konzepte haben wenig gemein mit dem oben genannten Vorschlag. Sie beziehen sich eher auf informelle Anforderungen, die in C++03 und C++11 verwendet werden, um das Verhalten und die erwarteten Eigenschaften verschiedener Typen zu definieren.
    Original:
    Here concepts have little in common with the abovementioned proposal. They refer to informal named requirements, used in C++03 and C++11 to define behavior and expected properties for various types.
