So lernen Sie Programmiermethoden wie auch algorithmische und mathematische Konzepte in Zusammenhang mit C++-spezifischen Elementen verstehen und beispielhaft anwenden. Doina Logofatu präsentiert sorgfältig ausgewählte Problemstellungen, die dem Leser den Übergang vom konkreten Praxisbeispiel zur allgemeinen Theorie erleichtern. Den Schwerpunkt bilden praktische Anwendungsbeispiele, die von der examine bis zum C++-Programm komplett behandelt werden.

Jedes challenge ist eine Fallstudie mit Beispielen, Analogien und detaillierten Erklärungen, ergänzt um entsprechend geeignete Übungen. Zu jedem gelösten challenge wird ein komplettes directory des Programms zusammen mit einem repräsentativen enter- und Output-Datenset geliefert. "Algorithmen und Problemlösungen mit C++" empfiehlt sich sowohl als Lern- und Arbeitsbuch für das Selbststudium wie auch für die direkte Verwendung in der Lehre.

Die zweite Auflage des erfolgreichen Buches wurde unter Berücksichtigung zahlreicher Leserstimmen überarbeitet und erweitert. Ergänzt wurden u. a. klassische Themen und Probleme wie Huffman-Kodierung, Kruskal- und LCS-Algorithmus sowie Sudoku aus der Spieltheorie.

"Studenten geraten nicht gerade ins Schwärmen angesichts staubtrockener akademischer Produkte [...]. Dass es auch ganz anders geht, beweist Logofatus Buch, das bereits 2001 in Rumänien erschienen ist und das die Verfasserin nun selbst übersetzt und erweitert hat. Statt abgeschmackter Such- und Sortieralgorithmen enthält es interessante und anspruchsvolle Algorithmen aus der diskreten Mathematik [...]. Das unterhaltsame Buch regt auch zum Knobeln und Experimentieren an."
