21世纪C语言（影印版）

   
是否你的C语言编程环境被限制在VI和CC上？是否C语言的内存管理机制依然像20世纪90年代那样困扰你？BEN
KLEMENS提出了这些常见的问题，并且展示了**的工具如何使得C语言编程变得简单——能够帮助你调试、跟踪内存泄露、组织编译过程和管理源代码版本。

     抛弃你对于C语言的那些陈旧观念吧。你应该重
新学习这门编程语言，它早已改变了过去的面貌。在 《21世纪C语言(影印版)》中，你将了解到在其他C语
言书籍中所缺失的那些*技术。C语言不仅仅是现 代编程语言的基石，它本身也是一门现代语言，尤其
适合于编写高效的、尖端的应用程序。你需要放弃那 些只有在大型机时代才有意义的旧习，转而选择相应
的工具来使用这门改进的极其简单的语言。无论目前 你是哪门编程语言的拥护者，你都不得不承认C语言 也很出色。
