拋棄你對于C語言的那些陳舊觀念吧。你應該重 新學習這門編程語言，它早已改變了過去的面貌。在 《21世紀C語言(影印版)》中，你將了解到在其他C語 言書籍中所缺失的那些技術。C語言不僅僅是現 代編程語言的基石，它本身也是一門現代語言，尤其 適合于編寫高效的、尖端的應用程序。你需要放棄那 些只有在大型機時代才有意義的舊習，轉而選擇相應 的工具來使用這門改進的極其簡單的語言。無論目前 你是哪門編程語言的擁護者，你都不得不承認C語言 也很出色。

是否你的C語言編程環境被限制在VI和CC上？是否C語言的內存管理機制依然像20世紀90年代那樣困擾你？BEN KLEMENS提出了這些常見的問題，并且展示了的工具如何使得C語言編程變得簡單——能夠幫助你調試、跟蹤內存泄露、組織編譯過程和管理源代碼版本。 《21世紀C語言(影印版)》的作者是克萊門斯。
