机工 码农修行:编写优雅代码的32条法则 林文 著

-----
如何打造精品软件一直是软件行业讨论的热点话题。初入职场的软件开发人员，多数都只是在学会了某种编程语言后就直接进行编程工作。但由于他们并未掌握编程中的一些有效方法，导致其开发的软件问题累累且工作效率不高。码农修行 编写优雅代码的32条法则针对这类人群提出了一些改善编程方法的建议，涉及具体编程工作的诸多方面，偏重于实践。书中大部分示例都是笔者实际编程工作中碰到过的真实案例，具有较高的参考价值。码农修行 编写优雅代码的32条法则从代码的可读性、可靠性、效率、可维护性、可扩展性5个方面，提出了编写代码的32 条法则。此外还公开了笔者自主编写的一款Android 小游戏源代码，希望能对读者有所帮助。 码农修行 编写优雅代码的32条法则适用于有一定编程基础、且想进一步提升个人编程能力的读者阅读，也可作为大中专院校计算机专业师生的教学参考用书。
