c++ - array of arrays of different size -

-

I have some code that sets one of different sizes of tr1 :: array, but the same type, like < / P> 

  Array & lt; Int, 2 & gt; Array & lt; Int, 4 & gt; Array & lt; Int, 6 & gt;

The numbers of these arrays, and their size, time are given in the compilation, so I know how many of them will be and how big they are (but they May be different).

The problem: I want to put them in a collection (using the array & gt; would be great), but for all the members the type should be identical and this is not the case.

I thought about using the Promotion: version, but how can I specify a type with compiled time determined list (I'm thinking of heavy use of preprocessor. ..)? About using promotion: Anyone? Other methods? (Wild pointer?)

TIA ~ AKI

Correction: Preprocessor is not usable in this case.

I will use Boost's MPL and Fusion Library to have two ways to end with the I type list. : Generate them, or explicitly define them. The former is slightly more flexible, but it's hard to say what's right for you because we do not know which values ​​you have.

In any case, to create: 

  #include & lt; Boost / mpl / for_each.hpp & gt; # Include & lt; Boost / mpl / range_c.hpp & gt; #include & lt; Boost / mpl / transform.hpp & gt; # Include & lt; Boost / mpl / vector.hpp & gt; # Include & lt; Array & gt; # Include & lt; Iostream & gt; Name Location bmpl = boost :: mpl; // turns an index into an array template & lt; Typename T & gt; Struct make_array {// or whatever plan gives you constant const. Std :: size_t size = t :: value * 2; // defined type type typedef std :: array & lt; Int, size & gt; type; }; Type a list of values ​​to type: bmpl :: range_c & lt; Size_t, 1, 10 & gt; Array_range; // change that list into arrays, a vector typepeed BMPL :: Transform & Lieutenant; Array_range, makere and lieutenant; BMPL :: _1 & gt; BMPL :: Back_Incenter & lt; BMPL :: Vector & lt; & Gt; & Gt; & Gt; :: type arrow_collection;

Or explicitly stating: 

  #include & lt; Boost / mpl / vector.hpp & gt; # Include & lt; Array & gt; # Include & lt; Iostream & gt; Name Location bmpl = boost :: mpl; // Type all array types bpmpl :: vector & lt; Std :: array & lt; Int, 2>, std :: arrays & lt; Int, 4>, std :: arrays and lt; Int, 6 & gt; std :: arrays & lt; Int, 8 & gt;, std :: array & lt; Int, 10 & gt; Std :: array & lt; Int, 12>, std :: arrays & lt; Int, 14 & gt; std :: arrays & lt; Int, 16 & gt; std :: array & lt; Int, 18 & gt; & Gt; Array_collection; By any means, you can use it like this:  
  #include & lt; Boost / fusion / algorithm.hpp & gt; #include & lt; Boost / fusion / container / vector.hpp & gt; #include & lt; Boost / fusion / mpl.hpp & gt; #include & lt; Boost / fusion / sequence.hpp & gt; #include & lt; Boost / mpl / for_each.hpp & gt; #include & lt; Typeinfo & gt; // Fusion "Fuses" MPL and Runtime Namespot BF = Boost :: Bridge between Fusion; Struct print_type {template & lt; Typename T & gt; Zero operator () (CONST T & amp;) const {std :: cout & lt; & Lt; Typid (t) .name () & lt; & Lt; "\ N"; }}; Struct print_values ​​{template & lt; Typename T & gt; Zero operator () (CONST T & PRRAR) const {std :: cout & lt; & Lt; "Printing array with size" & lt; & Lt; PArray.size () & lt; & Lt; ": \ N"; Std :: for_each (pArray.begin (), pArray.end (), [] (int pX) {std :: cout & lt; & lt; px & lt; & lt; "";}); Std :: cout & lt; & Lt; Std :: endl; }}; Int main (zeros) {// All types of bmpl :: for_each & lt; Array_collection & gt; (Print_type ()); Std :: cout.flush (); // Type Type Beef :: Results_of :: as_vector & lt; Array_collection & gt; :: type array_fusion; Use a useful type out of; Array_fusion arrays; // is now an array of different arrays, // compile-time generated, but run-time usable // like this: bf :: at_c & lt; 0 & gt; Arrays [1] = 5; Bf :: at_c & lt; 1 & gt; (Array) [2] = 7; Bf :: at_c & lt; 2 & gt; (Array) [0] = 135; // for_each: bf :: for_each (arrays, print_values ​​()); }

I'm new to this I'm writing a clr. stored procedure that can be used to get values ​​used in a calculation Call for another stored procedure for Gives an archived methodology int (I think SqlInt32?

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).
