After

i

is something like a 
  zero doSomething (int x) {.. .}} Zero fun () {#ifdef XXXX_1_YYYY doSomeThing (XXXX_1_YYYY); #endif // XXXX_1_YYYY #ifdef XXXX_2_YYYY doSomeThing (XXXX_2_YYYY); #endif // XXXX_2_YYYY #ifdef XXXX_3_YYYY doSomeThing (XXXX_3_YYYY); #endif // XXXX_3_YYYY #ifdef XXXX_4_YYYY doSomeThing (XXXX_4_YYYY); #endif // XXXX_4_YYYY .... until XXXX_20_YYYY}

Is there any way I can reduce this typing up to 20 using some macro extension technology or any other solution?

The macro definition can be something like this 

  #define XXXX_1_YYYY 10 #define XXXX_2_YYYY 20 #define XXXX_3_YYYY 30 #define XXXX_4_YYYY 40 ... #define XXXX_20_YYYY 200 < / Code>

Each #ifdef is not mutually exclusive Code is in C ++

A trivial answer is probably, but if they are all mutually exclusive, using #elif will save you a lot of #endifs.

It is difficult to know how to avoid this without knowing about a good way that you are actually trying to do. Are all those functions in the same file, each of which is # around it?

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
