　调试对于软件的成败至关重要，正确使用恰当的调试工具可以提高发现和改正错误的效率。本书详细介绍了 3种调试器，gdb用于逐行跟踪程序、设置断点、检查变量以及查看特定时间程序的执行情况， ddd是流行的 gdb的 gui前端，而 eclipse提供完整的集成开发环境。书中不但配合实例讨论了如何管理内存、理解转储内存、跟踪程序找出错误等内容，更涵盖了其他同类书忽略的主题，例如线程、客户 /服务器、gui和并行程序，以及如何躲开常见的调试陷阱。(Debugging for is vital to the success of the software, the proper use of appropriate debugging tool can improve the efficiency of discovery and correct mistakes. Book introduces in detail three kinds of debugger, GDB for tracking procedures, set breakpoints, line by line check variables and checking their specific time execution of DDD is popular the GDB GUI front-end, and eclipse provides a complete integrated development environment. The book not only cooperate with examples to discuss how to manage the memory, understanding, memory dump and trace program error, more covers other similar books ignore themes, such as threads, client/server, GUI, and the parallel program, debugging and how to avoid common pitfalls.)
