How to use enum within a struct in ANSI C? -

-

The following code is to be used in the main code, but I do not know how it is used. 

  START A few ITEM {enum {MOVIE, MUSIC} item type; Association (structure film * movie; composition music * music;};};

This structure is used in a dynamic link list with previous / item / next indicator, but not me Find out how you can set an enum or how to get started.

I have to know how this is seen in the main function.

biglist.someitem = ';; / * Declaration I * / struct Library * Use a large list;

To understand more code that I do Is trying to.

Struct library {struct SomeItem * someitem; straight Some Itam * Previous Itam; Straight Some Itam * Next Entom;}; C2037: Contiller Ideals: C2037: Regardless of 'something', the undefined structure / union specifies 'Library' C2065: Film: Undeclared identifier

Still a rookie on ANSI C, do not hit me properly;)

< / Div>

You are using points everywhere, so you can use Mitigation requires -> refer to the item.

Meaning biglist-> Someitem-> ItemType = MOVIE;

The code below is compiled exactly with gcc -Wall-strict:

{ENG} type {MOVIE, MUSIC} item type; Structure (structure film * movie; composition music * music;} item;}; structure library {strait someItem * someitem; straight some itam * previous itam; straight some etam * next int;}; int main (zero) {struct library * Big list-> Biglist-> itemty = MOVIE; return 0;}

(Although this code will not run definitely because I have a large list and someitem No memory for me!)

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).
