C语言对黑客来说有用吗
有用啊！至少是一门汇编语言，不过这离黑客还远的很，黑客要专攻网络知识，攻防都要学

c语言黑客编程
首先要熟悉编程语言。其次操作系统内核的东西及其网络要充分了解
c语言做出的程序都能干什么？一般黑客编写的入侵和攻击程序用的是什么语言？
C语言最大的应用就是写操作系统和驱动程序还有其他嵌入式系统的程序,学习程序设计选选择C是很好的,掌握的一定程度再学C++,java等就容易一些.
黑客工具的开发语言很多了,用java好像没听说,很多小工具是直接用的汇编,小榕暴强的扫描工具"流光"是C++ Builder开发的,现在很多菜鸟黑客甚至用中文编程语言(易语言)来开发一些工具软件.
