C/C++ Source Code Obfuscation Show

SourceFormatX is not only the multi-language code formatter but also a code obfuscator that can obfuscate your C and C++ source code for the purposes of source code security and intellectual property protection.

  C/C++ Source Code Obfuscation Examples:     Example 1   |   Example 2   |   Example 3

The purpose of this C code obfuscating sample is to show the power of SourceFormatX C/C++ Code Formatter's syntax parse engine.
