c++ - STL iterators and 'const' -

-

When I use the etherneters, I have a problem that appears to be some type of inserted molding. I'm not really sure which code is relevant (if I did then I probably would not ask this question.) Then I would do my best to describe my problem. 

  typedef set & lt; SmallObject & gt; Container; // Unconfigured zero videObject :: someFunction () {// const Container :: Not the Eaterator; // not for const (this = c. Beta (); it! = C.ed (); ++ this) {// value of "container" (* it is) .smallObjectFunction (); // one const function}}

However, I always get the following error: 

  Error: 'const smallobject' as 'this' argument Passing 'Intel Short Object: Small Object Function ()' Disclaims Qualifier

However, if I put it in the form of ((SmallObject) (* it) I'm getting rid of the error message.

The only thing I can understand is 

  The Bull Operator & Lt; (const smallobject & amp; a) cones

In some way causes the iterator to return the components. Any help or explanation is here?

Set and map order elements according to the order of the order. To break the inventory for user code, map key and the entire set The element should be stable. Your problem is that the archived element is not SmallObject , but const SmallObject .

If it was not limited you might have: 

  int init [] = {1, 2, 3, 4, 5}; Std :: set & lt; Integer & gt; Value (init, init + 5); Std :: copy (values.begin (), values.end (), std :: ostream_iterator & lt; int & gt; (std :: cout, "")); // 1 2 3 4 5 * (values.find (3)) = 5; // Luckily this does not work! Std :: copy (values.begin (), values.end (), std :: ostream_iterator & lt; int & gt; (std :: cout, "")); // 1 2 5 4 5 - not in order !!!

The problem is not that the set element will now be in order, but that how the tree was made, there may be elements present, but can not exist in the set.

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).
