Obfuscating C-based binaries to avoid decompilation

Question

Is there some way to obfuscate C-based executables or libraries to prevent decompilation?

Answer 1

"obfuscated executables" makes no sense. The hardware has to be able to "understand" the code in able to to execute it, and it the hardware can understand it, a reverse engineering human can understand it. The most you can do will be make it more tedious to understand, but probably not by much, and at a cost.
