C++ can't create vector -

-

It is weird that I made a vector right in a square but it has not been made in any other category. She has a representation to me:

main.h 

  #include & lt; Windows.h & gt; # Include & lt; Shellpi h & gt; # Include & lt; Vector & gt; #include & lt; String & gt; # Include & lt; Iostream & gt; # Included "Taco H" class MyClass {public: int nothingint; Of vector & lt; Int & gt; My order; };

Taco H 

  #include & lt; Vector & gt; Class other class {public: vector & lt; Int & gt; OtherOrder; };

And I compile errors regarding vector announcement in Taco: 

  error C2143: syntax error: missing ';' '& Lt;' Error before C4430: Missing type specifier - int assumed note: C ++ does not support the default-int error C2238: unexpected token predecessor ';'

What am I missing here? I can end the second vector declaration and compile it properly.

Try: 

  std :: vector & lt; Integer & gt; OtherOrder;

vector std is part of the namespace. This means that whenever you use a vector in a header file, you should include the std :: prefix.

The reason for this is that you can sometimes get it forgotten by forgetting that some of the included files can use the namespace std; In these, you allow the prefix to be omitted. However, you should avoid by using the keyword in the header file, as it will corrupt the namespace of any files that are included in .

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).
