Si les performances et la libert233 que le langage C++ offrent aux d233veloppeurs expliquent en grande partie son succ232s actuel, peu de programmeurs savent bien tirer parti des capacit233s de ce langage. Les Design Patterns sont des techniques de programmation efficaces et 233l233gantes, communes 224 plusieurs langages objet (Java, C++, Smalltalk...). L\'originalit233 et l\'attrait de l\'ouvrage est de permettre 224 un lecteur connaissant d233j224 les bases du langage d\'acqu233rir rapidement des connaissances pratiques pour ma238triser ces outils nouveaux et puissants. L\'objectif est de donner des cl233s pour produire plus simplement du code efficace, robuste et 233volutif. Les trois parties (les m233canismes virtuels, la STL et les Design Patterns) jalonnent une progression par 233tapes. The Desired Brand Effect Stand Out in a Saturated Market with a Timeless Brand
