文件有两种，一种是文本文件，一种是程序二进制文件，不管哪种文件都可以用十六进制编码来显示，称为hex文件。

1、文本Hex文件一般不需要转成C语言，更多的是程序二进制文件，用十六进制显示，可以转换成C语言，一般使用相应的反汇编程序来实现，这方面的工具很多，不同的平台略有不同。Windows平台一般常用的OllyDbg、Windbg、IDA，Linux平台使用最多的是GDB和Linux版的IDA(There are two kinds of files, one is a text file, the other is a program binary, which can be displayed in hexadecimal code, known as hex files.
1, text Hex file generally do not need to switch to the C language, is more of a binary program, using hexadecimal display, can be converted to the C language, generally use the corresponding disassembler to implement, this tool is very much, different platforms is slightly different.The most commonly used Windows platforms are OllyDbg, Windbg, IDA, and the most widely used Linux platforms are the GDB and the Linux version of IDA.)
