ios - Storing functions in an array and applying them to an array of numbers -


I have prototyped an algorithm in Python of my iOS game, and I would have to rewrite the ObjC actually, my There is a board of 16 numbers, and I should loop three numbers through each number and the four functions I am using (add, subtract, multiply, exponentiate). 1 + 2 + 3, 2 * 3-4, 3 ^ 4-5, 9-4 ^ 3, etc., but without the operation (first operation is always done first).

Would I like this to be an overview of how this can be implemented in objective C, in particular, what is the equivalent of an array of work in Objective-C? Is it an easy way to implement it with selectors? What is the best structure to use for loops with numbers? Array of NSInteger s, int s, NSArray / NSMutableArray of NSNumbers ? Random import as random = 0 maximum = 9 max_target = 20 max_to_calculate = 100 drt multiplication (x, y): return x * y def exponent (x, y): return x * Y def plus (x, y): return x + y def subtract (x, y): return x - y function_array = [multiply, exponate, add, subtract] board = [rand.randint (min, max) i For the board on the xchange (0, 16)] for dict_of_frequencies = {}: B in the board: for the first_fun in the function_arre: first_first = first_fone (A, B) in the board: function_array another function For: Last_reference = second_fone, C) if the last_start is not in digit_of_frequency: dict_of_frequencies [final_digital] = 0 dict_of_frequencies [last_right]] = =

The purpose of creating an array of functions- The most convenient way to use blocks is to use: 

  typedef NSIn teaser (^ Arithmetic Blak ) (NSiEtiger, NSINtega); ArithmeticBlock add = ^ NSInteger (NSInteger x, NSInteger y) {return x + y; }; Arithmetic Block All = ^ NSINtegaer (NSITGER X, NSINTG Y) {Return X - Y; }; NSArray * operation = @ [addition, sub]; Since :   
 Since it is to arithmetic on  NSNumber  s, it would be best to consider the value of the board such as  NSInteger  In a simple array, the  @ (board value)  gives you  NSNumber .

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

java - JPA TypedQuery: Parameter value element did not match expected type -

I am using JPA 2.0 and getting the following code in the DAO layer: Public Zero Test () {string key = "status"; String [] Conditions = {"A", "B"}; & Lt; TestTable & gt; Results = Search (Keys, Conditions); } Public listing & lt; TestTable & gt; Search (string key, object value error) {string sql = "test ndf to testlet and jade nand." + Key + "in:" + key; TypedQuery & LT; TestTable & gt; Query = entityManager.createQuery (SQL, TestTable.class); Query.setParameter (key, Arrays.asList (valueArr)) / *** Error Line *** Return query.getResultList (); } In the above error line, it throws the following exception: java.lang.IllegalArgumentException: parameter value element [[Ljava.lang.String; @ cbe5bc] did not match the expected type [java.lang.String] Why is this expected type string while actually this string []? Please help! Note: This is derived from the normal routine and is a simplified code. I can no...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
