EINE TOUR DURCH C++ // - Dieser Leitfaden will Ihnen weder das Programmieren beibringen noch versteht er sich als einzige Quelle, die Sie für die Beherrschung von C++ brauchen – aber diese Tour ist wahrscheinlich die kürzeste oder einfachste Einführung in C++11. - Für C- oder C++-Programmierer, die mit der aktuellen C++-Sprache vertrauter werden wollen - Programmierer, die in einer anderen Sprache versiert sind, erhalten ein genaues Bild vom Wesen und von den Vorzügen des modernen C++ . Mit dem C++11-Standard können Programmierer Ideen klarer, einfacher und direkter auszudrücken sowie schnelleren und effizienteren Code zu schreiben. Bjarne Stroustrup, der Designer und ursprüngliche Implementierer von C++, erläutert die Details dieser Sprache und ihre Verwendung in seiner umfassenden Referenz „Die C++-Programmiersprache“. In „Eine Tour durch C++“ führt Stroustrup jetzt die Übersichtskapitel aus der Referenz zusammen und erweitert sie so, dass auch erfahrene Programmierer in nur wenigen Stunden eine Vorstellung davon erhalten, was modernes C++ ausmacht. In diesem kompakten und eigenständigen Leitfaden behandelt Stroustrup – neben Grundlagen – die wichtigsten Sprachelemente und die wesentlichen Komponenten der Standardbibliothek. Er präsentiert die C++-Features im Kontext der Programmierstile, die sie unterstützen, wie die objektorientierte und generische Programmierung. Die Tour beginnt bei den Grundlagen und befasst sich dann mit komplexeren Themen, einschließlich vieler, die neu in C++11 sind wie z.B. Verschiebesemantik, einheitliche Initialisierung, Lambda-Ausdrücke, verbesserte Container, Zufallszahlen und Nebenläufigkeit. Am Ende werden Design und Entwicklung von C++ sowie die in C++11 hinzugekommenen Erweiterungen diskutiert. Programmierer erhalten hier – auch anhand von Schlüsselbeispielen – einen sinnvollen Überblick und praktische Hilfe für den Einstieg. AUS DEM INHALT // Die Grundlagen // Benutzerdefinierte Typen // Modularität // Klassen // Templates // Überblick über die Bibliothek // Strings und reguläre Ausdrücke // E/A-Streams // Container // Algorithmen // Utilities // Numerik // Nebenläufigkeit // Geschichte und Kompatibilität
