基本信息原书名：EffectiveC++:55SpecificWaystoImproveYourProgramsandDesigns(3rdEdition)原出版社：Addison-WesleyProfessional作者：(美)ScottMeyers译者：侯捷丛书名：传世经典书丛出版社：电子工业出版社ISBN：9787121123320出版日期：2011年1月开本：16开页码：336版次：3-1编辑本段编辑推荐传承大师智慧领悟技术本真经典名著翻译良品典藏不二之选编辑本段内容简介有人说c++程序员可以分为两类，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，波及整个计算机技术的出版领域，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崇。
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以伦比的表达能力，这使得它具有类似宗教般的魅力。
希望这本书能够帮您跨越c++的重重险阻，领略高处才有的壮美风光，做一个成功而快乐的c++程序员。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
