内容简介
有人说C++程序员可以分成两类,读过EffectiveC++的和没读过的。世界顶级C++大师ScottMeyers成名之作的第三版的确当得起这样的评价。当您读过这本书之后,就获得了迅速提升自己C++功力的一个契机。.在国际上,本书所引起的反响,波及整个计算技术出版领域,余音至今未绝。几乎在所有C++书籍的推荐名单上,本书都会位于前三名。作者高超的技术把握力、独特的视角。诙谐轻松的写作风格、独具匠心的内容组织,都受到极大的推崇和仿效。这种奇特的现象,只能解释为人们对这本书衷心的赞美和推祟。《EffectiveC++》前两个版本的确抓住了全世界无数程序员的目光。原因十分显明:ScottMeyers极富实践意义的C++研讨方式,描述出专家用以产出干净、正确、高效代码的经验法则和行事法则——也就是他们几乎总是做或不做的某些事。这本书不是读完一遍就可以束之高阁的快餐读物,也不是用以解决手边问题的参考手册,而是需要您去反复阅读体会的,C++是真正程序员的语言,背后有着精深的思想与无与伦比的表达能力,这使得它具有类似宗教般的魅力。希望这本书自瞄帮助您跨越C抖的重重险阻,领略高处才有的壮美风光,做—个成功而快乐的C++程序员。...本书一共组织55个准则,每一条准则描述一个编写出更好的C++的方式。每一个条款的背后都有具体范例支撑。第三版有一半以上的篇幅是崭新内容,包括讨论资源管理和模板(templates)运用的两个新章。为反映出现代设计考虑,对第二版论题做了广泛的修订,包括异常(exceptions)、设计模式(designpatterns)和多线程(multithreading)。《EffectiveC++》的重要特征包括:*高效的classes、functions、templates和inheritancehierarchies(继承体系)方面的专家级指导。*崭新的"TR1"标准程序库功能应用,以及与既有标准程序库组件的比较。*洞察C++和其他语言(例如Java、C#、C)之间的不同。此举有助于那些来自其他语言阵营的开发人员消化吸收C++式的各种解法。
作者简介
译者:侯捷台湾资深技术作家、译者。闲静少言。不慕荣利。好读书。求甚解。侯捷先生以为“任何书籍如果缺少读者,再怎么优秀都将丧失价值。因此,做为一位书评人,我非常乐见评选风气兴盛。虽然所谓“喜爱”带有很大的主观成份,但这类评选仍然具有十分正面的价值,可以带给读者、作者、译者、出版者很大的参与感,对于读书风气、好书浮现率都有帮助。”深入浅出MFC(第二版)>>更多作品ScottMeyersScottMeyers:世界顶级的C++软件开发技术权威之一。他是两本畅销书EffectiveC++和MoreEffectiveC++的作者,以前曾经是C++Report的专栏作家。他经常为C/C++UsersJournal和Dr.Dobb'sJournal撰稿,也为全球范围内的客户做咨询活动。他也是AdvisoryBoardsforNumeriXLLC和InfoCruiser公司的成员。他拥有BrownUniversity的计算机科学博士学位。>>更多作品
